How to make sidebar with same height as the content div?

Question

the code is the following:

(CSS)

#container {
    border:1px dashed #000;
    overflow:hidden;
}
#content, #sidebar {
    float:left;
    width:50%;
}
#content {
    background:yellow;
}

#sidebar {
    background:grey;
}

#sidebar {
    height:100%;
}

(HTML)

<div id="container">
    <div id="content">
        <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, Lorem ipsum dolor sit amet, consectetuer adipiscing elit</p>
    </div>
    <div id="sidebar">
        <p>Few words</p>
    </div>
</div>

I would like to see a #sidebar div with same height, like the #content div, is it possible without absolute position? Online version: http://jsfiddle.net/yJbUW/

Answer 1

You can do that by displaying the #container as table and displaying #content and #sidebar as table-cells:

#container {
    border:1px dashed #000;
    display: table;
    width: 100%;
}
#content, #sidebar {
    display: table-cell;
    width:50%;
}

You can also try below code

CSS goes here

#container {
    border:1px dashed #000;
    overflow:hidden;
}
#content, #sidebar {
    float:left;
    width:50%;
}
#content {
    background:yellow;
}

#sidebar {
    background:grey;
}


#Container
{
    height: auto;
    width: auto;
}

and update HTML as follows,

<div id="Container">
    <span id="content">
        <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, Lorem ipsum dolor sit amet, consectetuer adipiscing elit</p>
    </span>

    <span id="sidebar">
        <p>Few words</p>
    </span>
 </div>
