卡片是現代網頁設計中最通用的組件之一。它們用於以簡潔且具有視覺吸引力的方式呈現訊息,從線上商店中的產品到部落格上的文章。在本指南中,我們將探索不同的實作和最佳實踐。
一張典型的卡片由幾個元素組成:
<div> <h2> Implementaciones </h2> <h3> 1. Card Básica con CSS </h3> <pre class="brush:php;toolbar:false">.card { width: 300px; border-radius: 8px; overflow: hidden; box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1); transition: transform 0.2s ease; } .card:hover { transform: translateY(-4px); } .card-image { width: 100%; height: 200px; object-fit: cover; } .card-content { padding: 16px; } .card-title { margin: 0 0 8px; font-size: 1.25rem; } .card-description { color: #666; line-height: 1.5; } .card-footer { display: flex; justify-content: space-between; align-items: center; padding-top: 16px; margin-top: 16px; border-top: 1px solid #eee; }
<div> <h3> 3. Componente React con TypeScript </h3> <pre class="brush:php;toolbar:false">interface CardProps { image: string; title: string; description: string; action?: () => void; meta?: string; } const Card: React.FC<cardprops> = ({ image, title, description, action, meta }) => { return ( <div classname="card"> <img src="%7Bimage%7D" alt="{title}" classname="card-image" loading="lazy"> <div classname="card-content"> <h2 classname="card-title">{title}</h2> <p classname="card-description">{description}</p> <div classname="card-footer"> {action && ( <button onclick="{action}" classname="card-button"> Ver más </button> )} {meta && <span classname="card-meta">{meta}</span>} </div> </div> </div> ); }; </cardprops>
<template> <div> <h2> Patrones de Diseño </h2> <h3> 1. Card Grid Responsiva </h3> <pre class="brush:php;toolbar:false">.card-grid { display: grid; grid-template-columns: repeat(auto-fit, minmax(300px, 1fr)); gap: 24px; padding: 24px; }
.card-image-container { position: relative; padding-top: 56.25%; /* 16:9 Aspect Ratio */ } .card-image { position: absolute; top: 0; left: 0; width: 100%; height: 100%; object-fit: cover; }
.card-skeleton { animation: pulse 1.5s infinite; } @keyframes pulse { 0% { opacity: 0.6; } 50% { opacity: 1; } 100% { opacity: 0.6; } }
<div> <h2> Mejores Prácticas </h2> <ol> <li> <strong>Optimización de Imágenes</strong> </li> </ol> <pre class="brush:php;toolbar:false">import Image from 'next/image'; <image src="%7BimageUrl%7D" alt="{title}" width="{300}" height="{200}" placeholder="blur" blurdataurl="{thumbnailUrl}"></image>
const handleImageError = (e: React.SyntheticEvent<htmlimageelement>) => { e.currentTarget.src = '/placeholder.jpg'; }; <img src="%7BimageUrl%7D" onerror="{handleImageError}" alt="{title}"> </htmlimageelement>
.card-title { overflow: hidden; text-overflow: ellipsis; display: -webkit-box; -webkit-line-clamp: 2; -webkit-box-orient: vertical; }
/* Hover Effects */ .card { transition: all 0.3s ease; } .card:hover { transform: translateY(-4px); box-shadow: 0 12px 24px rgba(0, 0, 0, 0.15); } /* Click Effect */ .card:active { transform: translateY(-2px); box-shadow: 0 8px 16px rgba(0, 0, 0, 0.1); }

useEffect(() => { const observer = new IntersectionObserver( (entries) => { entries.forEach(entry => { if (entry.isIntersecting) { // Cargar contenido } }); }, { threshold: 0.1 } ); observer.observe(cardRef.current); return () => observer.disconnect(); }, []);
