Or, if you know the width of the two "side" images and don't want to deal with floats:
<div class="container">
<div class="left-panel"><img src="myleftimage" /></div>
<div class="center-panel">Content goes here...</div>
<div class="right-panel"><img src="myrightimage" /></div>
</div>
CSS:
.container {
position:relative;
padding-left:50px;
padding-right:50px;
}
.container .left-panel {
width: 50px;
position:absolute;
left:0px;
top:0px;
}
.container .right-panel {
width: 50px;
position:absolute;
right:0px;
top:0px;
}
.container .center-panel {
background: url('mymiddleimage');
}
Notes:
Position:relative on the parent div is used to make absolutely positioned children position themselves relative to that node.
