<h3>线性渐变 - 从上到下</h3><p>从顶部开始的线性渐变。起点是红色,慢慢过渡到蓝色:</p>
<div id="grad1"></div>
<p><strong>注意:</strong> Internet Explorer 9 及之前的版本不支持渐变。</p>

结果:
当然也可以从任意方向开始渐变:上到下;左到右;
对角
#grad1 { height: 200px; background: -webkit-linear-gradient(left top, red , blue); /* Safari 5.1 - 6.0 */ background: -o-linear-gradient(bottom right, red, blue); /* Opera 11.1 - 12.0 */ background: -moz-linear-gradient(bottom right, red, blue); /* Firefox 3.6 - 15 */background: linear-gradient(to bottom right, red , blue); /* 标准的语法(必须放在最后) */}</style></head><body>
<h3>线性渐变 - 对角</h3><p>从左上角开始(到右下角)的线性渐变。起点是红色,慢慢过渡到蓝色:</p>
<div id="grad1"></div>
结果:
角度
#grad1 { height: 100px; background: -webkit-linear-gradient(0deg, red, blue); /* Safari 5.1 - 6.0 */ background: -o-linear-gradient(0deg, red, blue); /* Opera 11.1 - 12.0 */ background: -moz-linear-gradient(0deg, red, blue); /* Firefox 3.6 - 15 */background: linear-gradient(0deg, red, blue); /* 标准的语法(必须放在最后) */}
透明度
#grad1 { height: 200px; background: -webkit-linear-gradient(left, rgba(255,0,0,0), rgba(255,0,0,1)); /* Safari 5.1 - 6.0 */ background: -o-linear-gradient(right, rgba(255,0,0,0), rgba(255,0,0,1)); /* Opera 11.1 - 12.0 */ background: -moz-linear-gradient(right, rgba(255,0,0,0), rgba(255,0,0,1)); /* Firefox 3.6 - 15 */background: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1)); /* 标准的语法(必须放在最后) */}
