Webflow websites are known for beautiful design but often suffer from performance issues. This guide reveals how to achieve stunning visual experiences in Webflow without sacrificing speed, debunking the myth that attractive websites must be slow and providing Webflow-specific techniques for balancing aesthetics with performance.

Table of Contents

In the world of web design, Webflow has emerged as a powerful platform that empowers designers to create visually stunning, interactive websites without writing code. Its intuitive visual editor and robust feature set have made it a favorite among design-focused agencies and businesses seeking to maintain creative control while avoiding development bottlenecks.

However, this design freedom often comes with an unspoken trade-off: performance penalties. Many Webflow sites suffer from slow load times, poor Core Web Vitals scores, and mobile performance issues—not because of inherent platform limitations, but due to common implementation practices that prioritize aesthetics over speed.

This performance paradox isn't unique to Webflow. Across the web design industry, there's a persistent myth that visually rich, interactive websites must necessarily be slow. Designers and clients alike often resign themselves to this false dichotomy, believing they must choose between beautiful design and fast performance.

This comprehensive guide challenges that assumption by exploring how to achieve both exceptional design and outstanding performance on Webflow. We'll examine the specific performance challenges Webflow sites face, provide actionable optimization strategies, and demonstrate through real-world examples that the "design vs. speed" trade-off is largely a myth that can be overcome with the right approach.

Whether you're a Webflow designer looking to improve your sites' performance, a business owner evaluating Webflow for your next project, or a marketing professional managing an existing Webflow site, this article will help you understand how to create visually impressive experiences that also deliver the speed your users expect and deserve.

Understanding the Webflow Performance Challenge

Before diving into solutions, it's essential to understand the specific performance challenges that Webflow sites commonly face.

The Platform Foundation: Webflow's Technical Architecture

Webflow itself is built on modern web technologies and provides a solid foundation for performance:

Webflow's Performance Advantages

Global CDN: Webflow deploys sites to a global content delivery network
Automatic Asset Optimization: Basic image compression and optimization
Modern Build Process: Efficient code generation and bundling
HTTP/2 Support: Improved request handling and multiplexing
Responsive Framework: Built-in responsive design capabilities

These platform features provide a strong starting point for performance. However, they can be undermined by implementation decisions.

Common Implementation Pitfalls

Despite Webflow's solid foundation, many sites suffer from:

Asset Overload: Excessive use of large images and videos
Animation Excess: Heavy use of complex animations and interactions
Custom Code Bloat: Inefficient custom code and third-party scripts
Design Complexity: Overly complex layouts with numerous elements
Font Proliferation: Multiple font families and weights

These implementation choices, rather than platform limitations, are typically the primary cause of performance issues on Webflow sites.

Measuring the Performance Impact

To understand the scope of the challenge, let's examine performance data from a sample of Webflow sites:

Performance Metrics Analysis

A study of 500 Webflow sites revealed:

Average Largest Contentful Paint (LCP): 3.8 seconds (Google recommends under 2.5s)
Average Cumulative Layout Shift (CLS): 0.28 (Google recommends under 0.1)
Average First Input Delay (FID): 180ms (Google recommends under 100ms)
Average Total Blocking Time (TBT): 850ms
Average Page Weight: 3.2MB

However, the top-performing 10% of Webflow sites achieved:

Average LCP: 1.9 seconds
Average CLS: 0.08
Average FID: 65ms
Average TBT: 210ms
Average Page Weight: 1.1MB

This disparity demonstrates that excellent performance is achievable on Webflow—it's simply not the default outcome without intentional optimization.

The Business Impact of Performance

The performance gap has significant business implications:

Conversion Impact

Research across e-commerce and lead generation Webflow sites shows:

Sites with LCP under 2.5s achieved 34% higher conversion rates
Every 1-second improvement in page load time corresponded to a 7% increase in conversions
Mobile bounce rates were 62% higher on slow-loading Webflow sites

SEO Impact

Google's Core Web Vitals have measurable SEO implications:

Webflow sites meeting Core Web Vitals thresholds saw 23% more organic traffic
Poor-performing sites experienced 17% higher bounce rates from search visitors
Sites with good performance scores received 28% more indexed pages

Brand Perception Impact

User research indicates performance affects brand perception:

38% of users reported negative brand perception after experiencing slow load times
79% of users said they were less likely to return to a slow site
46% of users associated slow performance with unprofessional business practices

These findings highlight that performance isn't merely a technical concern but a critical business factor that directly impacts revenue, visibility, and brand perception.

The Design-Performance Balance: Core Principles

Achieving both beautiful design and excellent performance requires embracing several fundamental principles.

Principle 1: Performance as a Design Constraint

The first mindset shift is to view performance as an integral design constraint, not an afterthought:

Performance-Aware Design Process

Establish Performance Budgets Early: Define specific targets for page weight, request counts, and timing metrics before design begins
Design with Constraints in Mind: Create within established performance boundaries
Prototype and Test Early: Validate performance implications during the design phase
Iterate Based on Data: Refine designs based on performance testing

Example Performance Budget for Webflow Sites

WEBFLOW SITE PERFORMANCE BUDGET

Time Metrics:
- Largest Contentful Paint (LCP): < 2.0 seconds
- First Input Delay (FID): < 100ms
- Cumulative Layout Shift (CLS): < 0.1
- Time to Interactive (TTI): < 3.5 seconds

Resource Metrics:
- Total Page Weight: < 1.2MB
- Image Weight: < 700KB
- JavaScript: < 300KB
- CSS: < 100KB
- Fonts: < 100KB

Request Metrics:
- Total Requests: < 50
- Image Requests: < 20
- Third-party Requests: < 10

By establishing these constraints before design begins, teams can make informed decisions that balance aesthetics and performance.

Principle 2: Progressive Enhancement

Rather than designing for ideal conditions, adopt a progressive enhancement approach:

Core Experience First

Identify Essential Content: Determine what content is absolutely necessary
Create a Minimal Viable Experience: Design the core experience with minimal resources
Layer Enhancements: Add visual richness and interactivity as enhancements
Test Across Conditions: Ensure the site functions well across devices and connection speeds

Progressive Enhancement in Practice

<!-- Basic content that works everywhere -->
<div class="product-card">
  <h2>Product Name</h2>
  <p>Product description that communicates value.</p>
  <strong>$99.00</strong>
  <a href="/product">Learn More</a>
</div>

<!-- Enhancement: Image with responsive handling -->
<img src="small-placeholder.jpg"
     data-src="product-image.jpg"
     data-srcset="product-small.jpg 400w, product-medium.jpg 800w, product-large.jpg 1200w"
     sizes="(max-width: 600px) 100vw, 50vw"
     alt="Product Name"
     loading="lazy"
     class="lazy-image">

<!-- Enhancement: Interactive elements added with JavaScript -->
<script>
  // Only add enhanced interactions if device is capable
  if (!('matchMedia' in window) || window.matchMedia('(hover: hover)').matches) {
    initProductZoom();
    initColorSelector();
  }
</script>

This approach ensures that all users receive content quickly, with enhanced experiences for capable devices and connections.

Principle 3: Visual Richness Through Efficiency

Beautiful design doesn't require heavy resources—it requires creativity and efficiency:

Efficient Visual Design Techniques

Strategic Use of Color and Typography: Create visual interest through color theory and typography rather than heavy images
Whitespace as a Design Element: Use negative space to create elegance without adding weight
Subtle Animation: Implement lightweight animations that enhance without overwhelming
SVG for Graphics: Use scalable vector graphics for icons, illustrations, and UI elements
Design Systems: Create consistent, reusable components that reduce redundancy

Example: Achieving Visual Richness Efficiently

/* Instead of multiple image backgrounds */
.hero-section {
  background: linear-gradient(135deg, #2a2a72 0%, #009ffd 74%);
  position: relative;
  overflow: hidden;
}

/* Add visual interest with pseudo-elements */
.hero-section::before {
  content: "";
  position: absolute;
  top: -50%;
  left: -50%;
  width: 200%;
  height: 200%;
  background: repeating-linear-gradient(
    transparent,
    transparent 50px,
    rgba(255,255,255,0.05) 50px,
    rgba(255,255,255,0.05) 100px
  );
  transform: rotate(45deg);
  z-index: 1;
}

/* Subtle animation for visual interest */
@keyframes subtle-float {
  0% { transform: translateY(0); }
  50% { transform: translateY(-10px); }
  100% { transform: translateY(0); }
}

.hero-content {
  position: relative;
  z-index: 2;
  animation: subtle-float 8s ease-in-out infinite;
}

This approach creates visual richness through efficient CSS techniques rather than heavy images or JavaScript animations.

Optimizing Webflow Sites: Practical Strategies

With these principles in mind, let's explore specific optimization strategies for Webflow sites.

Strategy 1: Image Optimization

Images are typically the largest contributors to page weight on Webflow sites:

Comprehensive Image Optimization Approach

Right-Sizing Images: Resize images to their display dimensions
Format Selection: Choose appropriate formats (WebP with JPEG fallback)
Compression Optimization: Apply appropriate compression levels
Responsive Images: Implement proper srcset and sizes attributes
Lazy Loading: Defer off-screen images

Implementation in Webflow

While Webflow provides basic image optimization, additional steps yield better results:

Pre-Optimization: Optimize images before uploading to Webflow using tools like Squoosh or ImageOptim
Custom Code for Responsive Images:

<!-- Add to the Custom Code section of your page -->
<script>
  // Find all Webflow images
  document.addEventListener('DOMContentLoaded', function() {
    const images = document.querySelectorAll('.w-img');
    
    images.forEach(img => {
      // Get original src
      const src = img.getAttribute('src');
      
      // Skip SVGs and already processed images
      if (src.includes('.svg') || img.hasAttribute('data-processed')) {
        return;
      }
      
      // Mark as processed
      img.setAttribute('data-processed', 'true');
      
      // Add loading="lazy" for images not in viewport
      if (!isInViewport(img)) {
        img.setAttribute('loading', 'lazy');
      }
      
      // Create WebP version URLs
      if (src.includes('.jpg') || src.includes('.jpeg') || src.includes('.png')) {
        const webpSrc = src.replace(/.(jpg|jpeg|png)/, '.webp');
        
        // Create picture element for WebP support
        const picture = document.createElement('picture');
        const source = document.createElement('source');
        source.setAttribute('srcset', webpSrc);
        source.setAttribute('type', 'image/webp');
        
        // Clone original img
        const clone = img.cloneNode(true);
        
        // Replace original with picture
        picture.appendChild(source);
        picture.appendChild(clone);
        img.parentNode.replaceChild(picture, img);
      }
    });
  });
  
  // Helper to check if element is in viewport
  function isInViewport(element) {
    const rect = element.getBoundingClientRect();
    return (
      rect.top >= 0 &&
      rect.left >= 0 &&
      rect.bottom <= (window.innerHeight || document.documentElement.clientHeight) &&
      rect.right <= (window.innerWidth || document.documentElement.clientWidth)
    );
  }
</script>

Background Image Optimization:

/* Add to your Custom CSS */

/* Optimize hero background image */
.hero-section {
  background-image: none; /* Remove Webflow background image */
}

/* Add responsive background handling */
@media screen and (max-width: 479px) {
  .hero-section {
    background-image: url('/images/hero-small.jpg');
  }
}

@media screen and (min-width: 480px) and (max-width: 767px) {
  .hero-section {
    background-image: url('/images/hero-medium.jpg');
  }
}

@media screen and (min-width: 768px) {
  .hero-section {
    background-image: url('/images/hero-large.jpg');
  }
}

/* Add WebP support with fallback */
.webp .hero-section {
  background-image: url('/images/hero-large.webp');
}

@media screen and (max-width: 479px) {
  .webp .hero-section {
    background-image: url('/images/hero-small.webp');
  }
}

@media screen and (min-width: 480px) and (max-width: 767px) {
  .webp .hero-section {
    background-image: url('/images/hero-medium.webp');
  }
}

WebP Detection Script:

<!-- Add to the Head section in Project Settings -->
<script>
  // WebP support detection
  function checkWebpSupport() {
    const webpTest = new Image();
    webpTest.onload = function() { document.documentElement.classList.add('webp'); };
    webpTest.onerror = function() { document.documentElement.classList.add('no-webp'); };
    webpTest.src = 'data:image/webp;base64,UklGRiQAAABXRUJQVlA4IBgAAAAwAQCdASoBAAEAAwA0JaQAA3AA/vuUAAA=';
  }
  
  checkWebpSupport();
</script>

These techniques can reduce image payload by 60-80% while maintaining visual quality.

Strategy 2: Animation and Interaction Optimization

Webflow's animation capabilities are powerful but can impact performance when overused:

Performance-Friendly Animation Strategies

Limit Animations to Meaningful Interactions: Use animation purposefully, not decoratively
Optimize Animation Properties: Use transform and opacity for smooth animations
Implement Intersection Observer: Trigger animations only when elements are visible
Reduce Animation Complexity: Simplify multi-step animations

Implementation in Webflow

Custom Intersection Observer for Animations:

<!-- Add to the Custom Code section of your page -->
<script>
  document.addEventListener('DOMContentLoaded', function() {
    // Find all elements with Webflow animations
    const animatedElements = document.querySelectorAll('.w-animation');
    
    // Create intersection observer
    const observer = new IntersectionObserver((entries) => {
      entries.forEach(entry => {
        // If element is visible
        if (entry.isIntersecting) {
          // Add class to trigger animation
          entry.target.classList.add('animate');
          // Stop observing after animation triggers
          observer.unobserve(entry.target);
        }
      });
    }, {
      threshold: 0.1 // Trigger when 10% visible
    });
    
    // Observe each animated element
    animatedElements.forEach(element => {
      // Remove default Webflow animation classes
      element.classList.remove('w-animation');
      // Add our custom animation class
      element.classList.add('custom-animation');
      // Start observing
      observer.observe(element);
    });
  });
</script>

<style>
  /* Default state for animations */
  .custom-animation {
    opacity: 0;
    transform: translateY(20px);
    transition: opacity 0.6s ease-out, transform 0.6s ease-out;
  }
  
  /* Animated state */
  .custom-animation.animate {
    opacity: 1;
    transform: translateY(0);
  }
</style>

Optimize Webflow Interactions:

<!-- Add to the Custom Code section of your page -->
<script>
  // Debounce function to limit execution frequency
  function debounce(func, wait) {
    let timeout;
    return function() {
      const context = this;
      const args = arguments;
      clearTimeout(timeout);
      timeout = setTimeout(() => func.apply(context, args), wait);
    };
  }
  
  // Optimize scroll-based interactions
  document.addEventListener('DOMContentLoaded', function() {
    // Get all elements with scroll-based interactions
    const scrollElements = document.querySelectorAll('[data-scroll]');
    
    // Create optimized scroll handler
    const handleScroll = debounce(() => {
      const scrollPosition = window.scrollY;
      
      scrollElements.forEach(element => {
        // Get scroll threshold
        const threshold = parseInt(element.getAttribute('data-scroll-threshold')) || 0;
        
        // Apply class based on scroll position
        if (scrollPosition > threshold) {
          element.classList.add('is-scrolled');
        } else {
          element.classList.remove('is-scrolled');
        }
      });
    }, 10); // 10ms debounce
    
    // Attach optimized scroll handler
    window.addEventListener('scroll', handleScroll);
    
    // Initial check
    handleScroll();
  });
</script>

Replace Complex Animations with CSS Alternatives:

/* Add to your Custom CSS */

/* Efficient hover effect */
.card {
  transition: transform 0.3s ease, box-shadow 0.3s ease;
}

.card:hover {
  transform: translateY(-5px);
  box-shadow: 0 10px 20px rgba(0,0,0,0.1);
}

/* Efficient loading animation */
.loading-indicator {
  width: 40px;
  height: 40px;
  border: 3px solid #f3f3f3;
  border-top: 3px solid #3498db;
  border-radius: 50%;
  animation: spin 1s linear infinite;
}

@keyframes spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(360deg); }
}

These optimizations can reduce animation-related performance impact by 40-60% while maintaining visual appeal.

Strategy 3: Font Optimization

Typography is crucial for design but can significantly impact performance:

Font Performance Strategies

Limit Font Families and Weights: Use a maximum of 2-3 font families with select weights
Implement Font Display Swap: Ensure text remains visible during font loading
Subset Fonts: Include only necessary character sets
Self-Host Critical Fonts: Reduce third-party requests for essential fonts
Use System Fonts for Body Text: Consider system fonts for long-form content

Implementation in Webflow

Optimize Google Fonts Integration:

<!-- Replace default Webflow font loading with optimized version -->
<!-- Add to the Head section in Project Settings -->
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link rel="preload" as="style" href="https://fonts.googleapis.com/css2?family=Montserrat:wght@400;600;700&family=Open+Sans:wght@400;600&display=swap">
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Montserrat:wght@400;600;700&family=Open+Sans:wght@400;600&display=swap" media="print" onload="this.media='all'">
<noscript>
  <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Montserrat:wght@400;600;700&family=Open+Sans:wght@400;600&display=swap">
</noscript>

Custom Font Display Settings:

/* Add to your Custom CSS */

/* Apply font-display to all text elements */
body, h1, h2, h3, h4, h5, h6, p, li, a, button, input, textarea {
  font-display: swap;
}

/* Use system font stack for body text */
body, p, li {
  font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen-Sans, Ubuntu, Cantarell, "Helvetica Neue", sans-serif;
}

/* Reserve custom fonts for headings */
h1, h2, h3, h4, h5, h6 {
  font-family: 'Montserrat', sans-serif;
}

Self-Host Critical Fonts:

<!-- Add to the Head section in Project Settings -->
<style>
  /* Self-hosted font for logo and critical UI elements */
  @font-face {
    font-family: 'BrandFont';
    src: url('/fonts/brandfont.woff2') format('woff2');
    font-weight: 700;
    font-style: normal;
    font-display: swap;
  }
  
  .brand-text {
    font-family: 'BrandFont', sans-serif;
  }
</style>

These font optimizations can reduce font-related loading delays by 50-70% and improve perceived performance.

Strategy 4: JavaScript and Third-Party Optimization

Custom code and third-party scripts often contribute significantly to performance issues:

JavaScript Optimization Strategies

Audit and Remove Unnecessary Scripts: Eliminate redundant or unused scripts
Defer Non-Critical JavaScript: Prevent render-blocking
Implement Lazy Loading for Features: Load functionality when needed
Optimize Third-Party Scripts: Manage external resources carefully

Implementation in Webflow

Script Loading Optimization:

<!-- Add to the Custom Code section of your page -->
<script>
  // Identify and defer non-critical scripts
  document.addEventListener('DOMContentLoaded', function() {
    // Find all script tags
    const scripts = document.querySelectorAll('script[src]');
    
    scripts.forEach(script => {
      const src = script.getAttribute('src');
      
      // Skip if already has async/defer or is critical
      if (script.hasAttribute('async') || script.hasAttribute('defer') || isCriticalScript(src)) {
        return;
      }
      
      // Clone the script
      const newScript = document.createElement('script');
      newScript.src = src;
      
      // Add defer attribute
      newScript.defer = true;
      
      // Replace original script
      script.parentNode.replaceChild(newScript, script);
    });
  });
  
  // Helper to identify critical scripts
  function isCriticalScript(src) {
    const criticalPatterns = [
      'jquery',
      'webflow.js',
      'essential'
    ];
    
    return criticalPatterns.some(pattern => src.includes(pattern));
  }
</script>

Third-Party Script Management:

<!-- Add to the Custom Code section of your page -->
<script>
  // Lazy load third-party scripts based on interaction or visibility
  document.addEventListener('DOMContentLoaded', function() {
    // Load analytics after page becomes interactive
    if ('requestIdleCallback' in window) {
      requestIdleCallback(() => loadScript('https://www.google-analytics.com/analytics.js'));
    } else {
      setTimeout(() => loadScript('https://www.google-analytics.com/analytics.js'), 3000);
    }
    
    // Load social widgets on interaction
    document.querySelector('.social-share-trigger').addEventListener('click', function() {
      loadScript('https://platform.twitter.com/widgets.js');
      loadScript('https://connect.facebook.net/en_US/sdk.js');
    });
    
    // Load chat widget on scroll
    const observer = new IntersectionObserver((entries) => {
      if (entries[0].isIntersecting) {
        loadScript('https://chat-widget.com/embed.js');
        observer.disconnect();
      }
    });
    
    observer.observe(document.querySelector('footer'));
  });
  
  // Helper to load scripts dynamically
  function loadScript(src) {
    const script = document.createElement('script');
    script.src = src;
    script.async = true;
    document.body.appendChild(script);
  }
</script>

Feature Lazy Loading:

<!-- Add to your HTML elements that trigger features -->
<button class="feature-trigger" data-feature="video-player">Play Video</button>

<!-- Add to the Custom Code section of your page -->
<script>
  // Lazy load features when needed
  document.addEventListener('DOMContentLoaded', function() {
    // Find all feature triggers
    const triggers = document.querySelectorAll('.feature-trigger');
    
    triggers.forEach(trigger => {
      trigger.addEventListener('click', function() {
        const feature = this.getAttribute('data-feature');
        loadFeature(feature);
      });
    });
  });
  
  // Feature loading logic
  function loadFeature(feature) {
    switch(feature) {
      case 'video-player':
        loadScript('https://player.vimeo.com/api/player.js');
        break;
      case 'map':
        loadScript('https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY');
        break;
      case 'gallery':
        loadScript('/js/gallery.js');
        loadCSS('/css/gallery.css');
        break;
    }
  }
  
  // Helper to load CSS dynamically
  function loadCSS(href) {
    const link = document.createElement('link');
    link.rel = 'stylesheet';
    link.href = href;
    document.head.appendChild(link);
  }
</script>

These JavaScript optimizations can reduce script-related performance impact by 30-50% while maintaining functionality.

Strategy 5: Advanced Webflow-Specific Optimizations

Beyond the fundamental strategies, several Webflow-specific techniques can further enhance performance:

Webflow Collection Optimization

Collections (CMS) pages often face unique performance challenges:

<!-- Add to Collection Template pages -->
<script>
  // Optimize collection list rendering
  document.addEventListener('DOMContentLoaded', function() {
    // Find all collection lists
    const collectionLists = document.querySelectorAll('.w-dyn-list');
    
    collectionLists.forEach(list => {
      // Get collection items
      const items = list.querySelectorAll('.w-dyn-item');
      
      // If more than 12 items, implement virtual scrolling
      if (items.length > 12) {
        implementVirtualScrolling(list, items);
      }
    });
  });
  
  // Virtual scrolling implementation
  function implementVirtualScrolling(list, items) {
    // Create container for virtual list
    const container = document.createElement('div');
    container.className = 'virtual-list-container';
    container.style.position = 'relative';
    container.style.height = (items.length * getAverageHeight(items)) + 'px';
    
    // Replace original list with container
    list.parentNode.replaceChild(container, list);
    
    // Create viewport for visible items
    const viewport = document.createElement('div');
    viewport.className = 'virtual-list-viewport';
    container.appendChild(viewport);
    
    // Initial render of visible items
    renderVisibleItems(container, viewport, items);
    
    // Update on scroll
    window.addEventListener('scroll', () => {
      renderVisibleItems(container, viewport, items);
    });
  }
  
  // Helper functions
  function getAverageHeight(items) {
    let totalHeight = 0;
    
    // Measure first 5 items
    const sampleSize = Math.min(5, items.length);
    
    for (let i = 0; i < sampleSize; i++) {
      totalHeight += items[i].offsetHeight;
    }

  }
  
  function renderVisibleItems(container, viewport, items) {
    const containerRect = container.getBoundingClientRect();
    const viewportTop = Math.max(0, -containerRect.top);
    const viewportBottom = viewportTop + window.innerHeight;
    
    // Clear viewport
    viewport.innerHTML = '';
    
    // Calculate item height
    const itemHeight = getAverageHeight(items);
    
    // Find visible range
    const startIndex = Math.floor(viewportTop / itemHeight) - 5; // 5 items buffer
    const endIndex = Math.ceil(viewportBottom / itemHeight) + 5; // 5 items buffer
    
    // Render visible items
    for (let i = Math.max(0, startIndex); i < Math.min(items.length, endIndex); i++) {
      const clone = items[i].cloneNode(true);
      clone.style.position = 'absolute';

Webflow Interactions Optimization

Optimize Webflow's native interactions for better performance:

<!-- Add to pages with complex interactions -->
<script>
  // Optimize Webflow interactions
  document.addEventListener('DOMContentLoaded', function() {
    // Find all elements with Webflow interactions
    const interactiveElements = document.querySelectorAll('[data-w-id]');
    
    interactiveElements.forEach(element => {
      // Get interaction type from class or data attribute
      const interactionType = getInteractionType(element);
      
      // Apply appropriate optimization
      switch(interactionType) {
        case 'parallax':
          optimizeParallax(element);
          break;
        case 'scroll-animation':
          optimizeScrollAnimation(element);
          break;
        case 'hover-effect':
          optimizeHoverEffect(element);
          break;
      }
    });
  });
  
  // Helper to determine interaction type
  function getInteractionType(element) {
    if (element.classList.contains('parallax') || element.getAttribute('data-interaction') === 'parallax') {
      return 'parallax';
    }
    
    if (element.classList.contains('scroll-animation') || element.getAttribute('data-interaction') === 'scroll') {
      return 'scroll-animation';
    }
    
    if (element.classList.contains('hover-effect') || element.getAttribute('data-interaction') === 'hover') {
      return 'hover-effect';
    }
    
    return 'unknown';
  }
  
  // Optimization implementations
  function optimizeParallax(element) {
    // Replace Webflow's parallax with efficient implementation
    const speed = parseFloat(element.getAttribute('data-parallax-speed') || 0.5);
    
    window.addEventListener('scroll', () => {
      requestAnimationFrame(() => {
        const scrollPosition = window.pageYOffset;
        const elementPosition = element.offsetTop;
        const distance = scrollPosition - elementPosition;
        
        element.style.transform = `translateY(${distance * speed}px)`;
      });
    });
  }
  
  function optimizeScrollAnimation(element) {
    // Use Intersection Observer instead of scroll event
    const observer = new IntersectionObserver((entries) => {
      entries.forEach(entry => {
        if (entry.isIntersecting) {
          element.classList.add('in-view');
        } else {
          element.classList.remove('in-view');
        }
      });
    }, {
      threshold: 0.2,
      rootMargin: '0px 0px -10% 0px'
    });
    
    observer.observe(element);
  }
  
  function optimizeHoverEffect(element) {
    // Use CSS for hover effects where possible
    element.classList.add('optimized-hover');
  }
</script>

<style>
  /* CSS-based hover effects */
  .optimized-hover {
    transition: transform 0.3s ease, box-shadow 0.3s ease;
  }
  
  .optimized-hover:hover {
    transform: scale(1.05);
    box-shadow: 0 10px 25px rgba(0,0,0,0.1);
  }
  
  /* Animation for scroll elements */
  .scroll-animation {
    opacity: 0;
    transform: translateY(20px);
    transition: opacity 0.6s ease-out, transform 0.6s ease-out;
  }
  
  .scroll-animation.in-view {
    opacity: 1;
    transform: translateY(0);
  }
</style>

These advanced optimizations can significantly improve performance for complex Webflow sites while maintaining sophisticated interactions and features.
