I designed a header image for my website, but I'm struggling to make it extend the full width of the user's web browser with black "bars" on the sides. I've attempted a few solutions, but haven't been successful so far.
Currently, my code looks like this:
#header {
background: url('img/header.png') no-repeat top center;
height: 131px;
}
#headerbg {
height: 131px;
width:4000px;
background-color:#000;
}
Both elements are contained in divs within each other in the HTML structure.
