How to set transparency in css
We often need to use CSS code to set the transparency of a DIV at work. Today I will introduce to you how to use a CSS style sheet to set the transparency and translucency of a DIV. Hope it helps everyone.
First let’s talk about the CSS code for setting DIV translucency:
div{filter:alpha(Opacity=80);-moz-opacity:0.5;opacity: 0.5;}Description:
1. Filter: Set the translucent filter effect for win IE, filter:alpha( Opacity=80) means that the object is 80% translucent, Firefox browser will not recognize it
2. -moz-opacity: achieve translucency for mozilla firefox Firefox browser, win IE will not recognize it For this attribute, -moz-opacity:0.5 is equivalent to setting the translucency to 50%
3. Opacity: supports all browsers except IE, including Google. The last one is mainly for Google Chrome, opacity: 0.5; Indicates setting 50% translucency
In order to observe the translucency of DIV, we set up two DIV layers, one inside the other DIV layer, and the outer DIV is named ".div-a"; The layer contained above CSS class is named ".div-b", forming a ".div-b" box and placing it inside ".div-a"
We set the underlying DIV A background is a picture with a DIV box above it set to black.
1. According to the described example, the translucent HTML source code is not set:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />

.div-a{ background:url(div-a-bg.png) no-repeat;width:230px;height:136px;padding:10px;}
.div-b{ background:#000;width:200px;height:100px;padding:5px;color:#F00}
</style>
</head>
<body>
<div class="div-a">
<div class="div-b">DIV半透明实例演示</div>
</div>

</html><!DOCTYPE html>

<style>
.div-a{ background:url(div-a-bg.png) no-repeat;width:230px;height:136px;padding:10px}
.div-b{ background:#000;width:200px;height:100px;padding:5px;color:#F00;
filter:alpha(Opacity=60);-moz-opacity:0.6;opacity: 0.6}
/* CSS注释说明：这里对CSS代码换行是为了让代码在此我要中显示完整，换行后CSS效果不受影响 */
</style>
</head>
<body>
<div class="div-a">
<div class="div-b">实现DIV半透明实例演示</div>
