我遇到了一个将渐变过滤器设置为整个网页的项目 所以我已经实现了这样的过滤器。jsfiddle
HTML
<div class="container">
<button class="tag">Featured</button>
<div id="grad1">
</div>
CSS
#grad1 {
height: 200px;
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(red, yellow); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(red, yellow); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(red, yellow); /* For Firefox 3.6 to 15 */
background: linear-gradient(red, yellow); /* Standard syntax (must be last) */
opacity: 0.5;
}
.container {
border: 1px solid #DDDDDD;
width: 200px;
height: 200px;
position: relative;
}
.tag {
float: left;
position: absolute;
left: 0px;
top: 0px;
background-color: #92AD40;
padding: 5px;
color: #FFFFFF;
font-weight: bold;
}
但问题是在这种情况下按钮不可选。 我不知道如何使按钮工作。 如何使按钮可选,并在按钮上方显示渐变?
