CSS Create a transparent div
Is there a way to make a div HTML el开发者_运维问答ement half transparent?
With CSS, this is cross browser solution
div {
opacity: 0.5;
filter: alpha(opacity = 0.5);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.5);
}
This will work with every browser
div {
-khtml-opacity:.50;
-moz-opacity:.50;
-ms-filter:”alpha(opacity=50)”;
filter:alpha(opacity=50);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.5);
opacity:.50;
}
If you don't want transparency to affect the entire container and it's children, check this workaround http://www.impressivewebs.com/css-opacity-that-doesnt-affect-child-elements/
Using a background PNG file which is half transparent, and hoping you don't have to support IE6?
If you only want the background of your div semi-transparent, not any text and elements inside it, you can simply set a background-color to a transparent-one (i.e. with alpha < 1).
One example is at our website, a minimized example here:
<html>
<head>
<title>Transparency test</title>
<style type="text/css">
body {
background-image: url(http://www.fencing-game.de/style/background6.png);
}
#trans {
background-color: rgba(255,0,0,0.5);
max-width: 80ex;
}
p {
max-width: 70ex;
margin: auto;
}
#nontrans {
background-color: rgb(255,255, 0);
}
</style>
</head>
<body>
<div id="trans">
<p>normal text</p>
<p id="nontrans">nontransparent</p>
<p>normal text</p>
</div>
</body>
