我有两层,我喜欢两层,我如何改变其透明度,使之能从上层重叠地区看到。
您需要使用<条码>z-index,>>> > > > 和<条码>。
<>光>:
<div id="layer1"></div>
<div id="layer2"></div>
<>CSS:
#layer1, #layer2 {
position:absolute;
top:0;
left:0;
width:500px;
height:500px;
}
#layer1 {
z-index:0;
background-color:red;
}
#layer2 {
z-index:1;
background-color:blue;
opacity:0.5;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
filter: alpha(opacity=50);
}
您需要使用特别安全局,并使用<>opacity标签。 它需要工作范围,因为旧的电子计算机需要非标准的环境,但这是一个例子:
.transparentLayer {
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)"; // IE8
filter: alpha(opacity=50); // IE7 or older
opacity: 0.5; // all real browsers
}
将<代码>0.5或50
改为你想要的不透明程度(0=clear, 1/100=solid)。
Use the CSS3 opacity
property, or the rgba
or hsla
notation for the background color of the element, depending on what effect you want to achieve. See: http://jsfiddle.net/minitech/sN8uU/
