我使用了 ColorZilla 的渐变编辑器和 ColorZilla Chrome 扩展来查找您发布的渐变的上限和下限。然后我使用渐变编辑器生成的 CSS 规则集制作了两个 div 元素。我将一个嵌套在另一个内部,并给出了内部 div opacity: .5
。
HTML:
<div class="gradient" style="width: 400px; height: 100px;">
<div class="topGradient" style="width: 400px; height: 100px; opacity: 0.5"></div>
</div>
CSS:
.topGradient {
background: rgb(204,204,204); /* Old browsers */
background: -moz-linear-gradient(top, rgba(204,204,204,1) 0%, rgba(255,255,255,1) 22%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(204,204,204,1)), color-stop(22%,rgba(255,255,255,1))); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, rgba(204,204,204,1) 0%,rgba(255,255,255,1) 22%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, rgba(204,204,204,1) 0%,rgba(255,255,255,1) 22%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, rgba(204,204,204,1) 0%,rgba(255,255,255,1) 22%); /* IE10+ */
background: linear-gradient(to bottom, rgba(204,204,204,1) 0%,rgba(255,255,255,1) 22%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#cccccc', endColorstr='#ffffff',GradientType=0 ); /* IE6-9 */
}
.gradient {
background: rgb(224,224,224); /* Old browsers */
background: -moz-linear-gradient(left, rgba(224,224,224,1) 0%, rgba(255,255,255,1) 35%, rgba(204,204,204,1) 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, right top, color-stop(0%,rgba(224,224,224,1)), color-stop(35%,rgba(255,255,255,1)), color-stop(100%,rgba(204,204,204,1))); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(left, rgba(224,224,224,1) 0%,rgba(255,255,255,1) 35%,rgba(204,204,204,1) 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(left, rgba(224,224,224,1) 0%,rgba(255,255,255,1) 35%,rgba(204,204,204,1) 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(left, rgba(224,224,224,1) 0%,rgba(255,255,255,1) 35%,rgba(204,204,204,1) 100%); /* IE10+ */
background: linear-gradient(to right, rgba(224,224,224,1) 0%,rgba(255,255,255,1) 35%,rgba(204,204,204,1) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#e0e0e0', endColorstr='#cccccc',GradientType=1 ); /* IE6-9 */
}
最终结果是这样的:
这是一个JSFiddle。
