[s32ialx]

Hi ok i'm attemtping to design a web 2.0 look site. i cannot give you the exact site but i will show exactly what i am trying to acomplish
ok so here is the basic look i am going for

ok so basicly what i have done is

<div class="content">
	<div class="ctl"></div><div class="ctm"></div><div class="ctr"></div>
		<div class="cml"></div><?php include('example.php') ?><div class="cmr"></div>
	<div class="cbl"></div><div class="cbm"></div><div class="cbr"></div>		
</div>

css

.content {
	position:absolute;
	top: 180px;
	right: 300px;
	left: 275px;
	height: 450px;
	width: 785px;
	margin-left: auto;
	margin-right: auto;	
}
.ctl { 
	position: absolute;
	background-image: url('images/ctl.png');
	top: 0px;
	left: 0px;
	height: 41px;
	width: 41px;
	z-index: 3;
}
.ctm {
	position:relative;
	background-image: url('images/ctm.png');
	top: 0px;
	left: 41px;
	right: 41px;
	height: 41px;
	width:100%;
	z-index: 3;
}
.ctr {
	position:absolute;
	background-image: url('images/ctr.png');
	top: 0px;
	right: 0px;
	height: 41px;
	width: 40px;
	z-index: 3;
}

now what happens is this

any possible way to make ctm stop 100% when it reach's ctr

index
CTL - Content Top Left
CTM - Content Top Middle
CTR - Content Top Right
CML - Content Middle Left
etc
