Css background layers and 100% height div's
Imagine the following code.
<body id="first_bg_layer">
<div id="second_bg_layer">
<div id="third_bg_layer">
</div>
</div>
</div>
Each layer has a different background that is static/repeated to achieve the desired effect. I need all layers to fill up the screen, otherwise the bac开发者_开发知识库kground will be broken. The background is split in layers to minimize the image sizes.
Setting min-height to 100% doesn't work for various reasons. Is there any way to do this?
Edit: If I set #second_bg_layer to height:100% and #third_bg_layer to min-height:100%, that works. But then the #second_bg_layer is locked to 100%, and will not be expanded more.
What I want to do is to set the min-height on both div's, or some other solution.
Is a trick I read sometime ago, and applied as seen bellow, if I recall well... As said just above by others for the first part, I'd set :
html,html body {height:100%;}
Then, a div containing all content. A sort of wrapper if you want to call it so.
...wrapper div to which I'd set {height:100%;min-height: 100%;} In its class or id.
But sadly IE does not support min-height, nor height:auto, so...
just set first the IE case line: {height: 100%;}
and then the css that will apply to other browsers:
html>body whatever_the_div_class {height: auto;min-height: 100%;}
Finally, do a footer div to put it outside this wrapper div, just after it, to which css properties you will add:
height 1%; clear:both (the 1% is like often happens, IE needs some "space" or will do weird things)
Well, let's hope it helps :)
Did you set the HTML and BODY height to 100% with 0 margins? If not, do that, if so, make sure your div elements are positioned correctly.
If you just aren't getting a full width and height out of the body area, then maybe what you are asking for is this:
html, body {
height: 100%; width: 100%;
}
/* And perhaps adding this if you're not using any reset CSS */
html, body {
margin: 0; padding: 0;
}
If its not, I'm not sure what you are having trouble with, but a background-image cannot be displayed outside of its selected element. If you want to differ the background layer from the layer itself then I would suggest using an additional div that has width/height: 100%; position: absolute; top/left: 0; and background: url(...); to hold the background image.
