Question

I have been given a challenge of recreating a certain website but I am unsure what the best way is to create a full width cross browser template. I would be using HTML 5 and so far I have:

Do I just use 100% as width?

HTML

<div id="wrapper">
    <header>
        <h1>Logo Position</h1>
        </header>

CSS:

#wrapper{
    width:990px;
    height:100%;
    min-height:100%;
    background:#000;
}
header{
    width:100%;
    height:100px;
    color:#184C82;
}

Answer 1

You should also use like that..

#wrapper {
 width:100%; /* or width:990px; */
 height:100%;
 position:absolute;
}
