$("html").fadeTo("slow",0.5);
OR
$("html").css({ 'opacity':'0.5' });
Why does either of these scripts whiten the page? I need it to become darker, no whiter, and usually that's what opacity doe开发者_Python百科s but not here...
How can I set a black opacity to my html with jquery?
Add a black div and fade it in on top of everything
HTML:
<body>
<div id="cover"></div>
</body>
CSS:
#cover {
height:100%;
width:100%;
background-color:#000;
display:none;
position:absolute;
top:0;
left:0;
z-index:99999999;
}
JQuery:
$('#cover').fadeTo("slow",0.5);
Here's a working example: http://jsfiddle.net/AlienWebguy/GM2Z6/2/
