🛠️ Implementación Técnica
1. Optimización de Imágenes
<!-- Preload Critical Images -->
<link rel="preload" as="image" href="/images/hero-bg.webp">
<!-- Lazy Loading -->
<img src="placeholder.jpg"
data-src="real-image.webp"
loading="lazy"
alt="Product description"
width="300"
height="200">
<!-- Responsive Images -->
<picture>
<source media="(min-width: 768px)" srcset="image-desktop.webp">
<source media="(min-width: 480px)" srcset="image-tablet.webp">
<img src="image-mobile.webp" alt="Description" loading="lazy">
</picture>
2. CSS Crítico Inline
<style>
/* Critical CSS for above-the-fold content */
.hero {
background: linear-gradient(135deg, #E0A73A 0%, #F4D03F 100%);
min-height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}
.header {
position: fixed;
top: 0;
width: 100%;
z-index: 1000;
background: rgba(255, 255, 255, 0.95);
backdrop-filter: blur(10px);
}
</style>
<!-- Load non-critical CSS asynchronously -->
<link rel="preload" href="/styles/non-critical.css" as="style" onload="this.onload=null;this.rel='stylesheet'">
3. JavaScript Optimizado
<!-- Defer non-critical JavaScript -->
<script src="/js/critical.js"></script>
<script src="/js/non-critical.js" defer></script>
<!-- Service Worker for caching -->
<script>
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('/sw.js');
}
</script>
4. Optimización de Fuentes
<!-- Preload critical fonts -->
<link rel="preload" href="/fonts/main.woff2" as="font" type="font/woff2" crossorigin>
<!-- Font display swap -->
<style>
@font-face {
font-family: 'MainFont';
src: url('/fonts/main.woff2') format('woff2');
font-display: swap;
}
</style>
