How To Display Code Examples On Your Website Tutorial

What is the "best" way to show code examples one your site? Well, after doing a lot of research and even more trial and error, I came to the conclusion that using the <pre> tag was the best way to show my code examples. Mainly, because it gave me the ability to give my <pre> a max-height. However, before you place your code on your site, you will need to use a code converter to change all these < > to these &lt; &gt;. This prevents the browser from trying to render your code. Then just copy and paste it into your <pre> and your done!

pre {
display:block;
border:#000 solid 1px;
overflow:auto;
max-height:340px;
font-size:12px;
width:535px;
padding:10px;
background:#E0E0E0;
margin:2em 0;
}	
		

If you want your code to wrap, then use the rules below as well. However, you will find, as I did, that a few of these do not validate. Although I recently read that the W3C is planning on including word-wrap: break-word; in CSS-3. So soon we can have our cake and eat it too.

pre {
white-space:pre-wrap;/* css-3 problematic browser support */
}
		

If you want IE6 to have a max-height as well, then you'll need to feed it an IE expression to simulate max-height.

pre { 
   height: 340px; /* defaults to this height if JS is turned off */
   height: expression( this.scrollHeight > 339 ? "340px" : "auto" );
}
		

IE expressions don't validate though, so place the above IE specific code in a seperate ie6.css and link to it by placing this in the <head>.

<!--[if IE 6]>
<link href="ie6.css" rel="stylesheet" type="text/css" media="screen">
<![endif]-->
