Key Technical Features

High-Performance Animations

CSS Animations IntersectionObserver Passive Triggers

Implemented hardware-accelerated animations using CSS transforms and opacity properties with the Intersection Observer API to create smooth 60fps animations that only trigger when elements enter the viewport.

                                            
                                            
                                            
                                        
animations.js

const observer = new IntersectionObserver((entries) => {
  entries.forEach(entry => {
    if (entry.isIntersecting) {
      entry.target.classList.add('animate-in');
      observer.unobserve(entry.target);
    }
  });
}, { threshold: 0.15 });

document.querySelectorAll('.animate-on-scroll').forEach(el => {
  observer.observe(el);
});
                                    

Dynamic Template Previews

JavaScript DOM Manipulation Event Delegation

Engineered an interactive template showcase system that allows users to preview different designs, using efficient event delegation and smooth transitions.

                                            
                                            
                                            
                                        
templates.js

const templateContainer = document.querySelector('.template-container');
const templatePreviews = document.querySelectorAll('.template-preview');

// Event delegation for better performance
templateContainer.addEventListener('click', (e) => {
  const button = e.target.closest('.preview-button');
  if (!button) return;
  
  const templateId = button.dataset.template;
  
  // Transition out current template
  const currentTemplate = document.querySelector('.template-active');
  if (currentTemplate) {
    currentTemplate.classList.add('template-exit');
    currentTemplate.addEventListener('animationend', () => {
      currentTemplate.classList.remove('template-active', 'template-exit');
    }, { once: true });
  }
  
  // Transition in new template
  const newTemplate = document.getElementById(templateId);
  if (newTemplate) {
    newTemplate.classList.add('template-active', 'template-enter');
    newTemplate.addEventListener('animationend', () => {
      newTemplate.classList.remove('template-enter');
    }, { once: true });
  }
});
                                    

Responsive Grid Layout System

CSS Grid Flexbox Custom Properties

Designed a flexible grid system using CSS Grid and custom properties to create a consistent layout that adapts to any viewport size without relying on external frameworks.

                                            
                                            
                                            
                                        
grid.css

:root {
  --grid-columns: 12;
  --grid-gap: clamp(1rem, 2vw, 2rem);
  --container-max-width: 1200px;
  --container-padding: clamp(1rem, 5vw, 3rem);
}

.grid-container {
  display: grid;
  grid-template-columns: repeat(var(--grid-columns), 1fr);
  gap: var(--grid-gap);
  width: 100%;
  max-width: var(--container-max-width);
  margin: 0 auto;
  padding: 0 var(--container-padding);
}

/* Responsive column spans */
.col-span-12 { grid-column: span 12; }
.col-span-6 { grid-column: span 6; }
.col-span-4 { grid-column: span 4; }

@media (max-width: 768px) {
  .col-span-6 { grid-column: span 12; }
  .col-span-4 { grid-column: span 6; }
}

@media (max-width: 480px) {
  .col-span-4 { grid-column: span 12; }
}
                                    

Performance Optimization

Lazy Loading Code Splitting Resource Hints

Implemented various performance techniques including lazy loading of images and components, code splitting, and resource hints to achieve excellent Lighthouse scores.

                                            
                                            
                                            
                                        
performance.js

                            // Lazy loading images implementation
                            document.addEventListener("DOMContentLoaded", function() {
                            const lazyImages = document.querySelectorAll(".lazy-image");
                            
                            if ("IntersectionObserver" in window) {
                                const imageObserver = new IntersectionObserver((entries) => {
                                entries.forEach(entry => {
                                    if (entry.isIntersecting) {
                                    const image = entry.target;
                                    image.src = image.dataset.src;
                                    imageObserver.unobserve(image);
                                    }
                                });
                                });
                                
                                lazyImages.forEach(image => imageObserver.observe(image));
                            } else {
                                // Fallback for browsers without IntersectionObserver
                                lazyImages.forEach(image => {
                                image.src = image.dataset.src;
                                });
                            }
                            });

                            // Resource preloading for critical assets
                            function preloadCriticalAssets() {
                            const preloads = [
                                { href: '/assets/css/main.css', as: 'style' },
                                { href: '/assets/js/main.js', as: 'script' }
                            ];
                            
                            preloads.forEach(resource => {
                                const link = document.createElement('link');
                                link.rel = 'preload';
                                link.href = resource.href;
                                link.as = resource.as;
                                document.head.appendChild(link);
                            });
                            }

                            // Execute performance optimizations
                            preloadCriticalAssets();

Technical Challenges & Solutions

Interactive Templates Without Framework

Challenge: Creating rich, interactive templates without relying on heavy frameworks.

Solution: Developed a lightweight custom JavaScript component system that handles template previews and interactions, improving load times and reducing bundle size.

Complex Animations with Performance

Challenge: Implementing complex animations without sacrificing performance.

Solution: Created an animation pipeline that prioritizes compositor-only properties (transform, opacity) and uses requestAnimationFrame for JavaScript animations, ensuring smooth 60fps performance.

Maintaining Visual Consistency

Challenge: Ensuring visual consistency across different components and screen sizes.

Solution: Developed a custom design system with CSS custom properties for colors, spacing, typography, and shadows to maintain visual consistency while enabling easy theming.

Cross-Browser Compatibility

Challenge: Ensuring consistent experience across different browsers and devices.

Solution: Implemented a robust testing strategy with targeted polyfills and fallbacks for specific features, ensuring consistent experience across Chrome, Firefox, Safari, and Edge.
