In my posts I have put some code-snippets. I got some questions on how I did this. Well, to be honest, it is very easy.
am using the <pre>-tag inside my post. Anything that is put
between a <pre> and a </pre>-tag is handled by your browser
as pre-formatted, and your browser leaves it as it is. You can add some
styling to it inline, such as <pre
style="font-size:90%;color:#009000;">, or you can add a class
definition to your template skin.
If you want to display html-code
inside your post, be aware that you have to replace every < by
<, and every > by >.
