HTMLHelp Forums _ Cascading Style Sheets _ Aligning container div to floating divs

Posted by: EugeneG May 2 2012, 09:40 AM

I am trying to get a div with a background colour and margin to contain two floating divs. Problem is that the container div's colour and margin does not extend to the bottom of the largest floating div.

CODE

<head>
<style type="text/css">
.container_div {
    width: 98%;
    padding: 0px 10px 10px 10px;
    margin-right: auto;
    margin-left: auto;
}
.main_div {
    width: 98%;
    padding: 10px;
    background-color: #FFFFCC;
    border: thin solid #800000;
    text-align: left;
    clear: both;
}
.leftcolumn {
    float: left;
    width: 49%;
}
.rightcolumn {
    float: right;
    width: 49%;
    border-left-width: thin;
    border-left-style: solid;
    padding-left: 1ex;
}
</style>
</head>

<body>

<div class="container_div">
    <div class="main_div">
        <div class="leftcolumn">
            gsdgdfhg sdfg sdfg fdgdfg gsdgs gsdgdfhg sdfg sdfg fdgdfg gsdgsgsdgdfhg
            gsdgsgsdgdfhg sdfg sdfg fdgdfg gsdgsgsdgdfhg sdfg sdfg fdgdfg gsdgsgsdgdfhg
            sdfg fdgdfg gsdgsgsdgdfhg sdfg sdfg fdgdfg gsdgsgsdgdfhg sdfg sdfg fdgdfg
            gsdgsgsdgdfhg sdfg sdfg fdgdfg gsdgs gsdgdfhg sdfg sdfg fdgdfg sdfg
            fdgdfg gsdgsgsdgdfhg sdfg sdfg fdgdfg gsdgs</div>
        <div class="rightcolumn">
            gsdgdfhg sdfg sdfg fdgdfg gsdgs gsdgdfhg sdfg sdfg fdgdfg gsdgsgsdgdfhg
            sdfg fdgdfg gsdgsgsdgdfhg sdfg sdfg fdgdfg gsdgs</div>
        after right col </div>
    after main </div>

</body>

Sounds like you need to clear the floats.

Option 3 is well tried.

So simple once you know how.
overflow: auto; (option 1) did it for me.
Many thanks Pandy.
