This is a tutorial I made, it's on my site. Enjoy!

Showing HTML
There are three ways of doing this-adding character codes, the XMP tag, and text boxes.


Pointers
Replace the "<" sign/s with this:

&amp;lt;

and the ">" sign/s with this:

&amp;gt;



XMP tag
This also acts as a double and can display things like &amp;lt/&amp;gt without it turning into "<" or ">"!

<xmp>your HTML you want to show goes here</xmp>

Text Boxes
Also known as text areas, these are good for long pieces of code, like Javascripts.

<form><textarea name="name" rows="#" cols="#">HTML you want to show</textarea></form>

*edited by admin: text area doesn't work on Netscape without form tags :D

Change the rows and cols attributes to change the size, and make a name for it!

That's all there is to it.
