Three columns layout without table
Computer monitors are getting bigger and bigger, so do the html pages. People start to add more columns into the layout.
To create a three columns layout, in a very traditional way you can do it in a table, like this:
<table> <tr><td>Left</td><td>Main</td><td>Right</td><tr> </table>
There are some obvious downside on this:
- Mix data and presentation
- Not browser friendly, try to browser this use a mobile phone? I am not saying iPhone or iPod Touch.
So how to fix it? You can use css with “position: absolute;” or “Float”:
<div id="wrapper">
<div id="main">
<div id="sideleft">Left column</div>
<div id="sideright">Right column</div>
<div id="content">Content</div>
</div>
</div>
#wrapper {width: 800px;}
#main {margin-top: 10px;}
#sideleft {float: left; width: 200px; border: 1px solid black; background-color: #dddddd;}
#sideright {float: right; width: 200px; border: 1px solid green; background-color: #99ff99;}
#content {border: 1px solid blue; background-color: #9999ff; margin: 0 20px 0 10px;}
