Hi Naomi,
You'd have to save the html in a zip file before attaching it to this forum (for security reasons).
As to your question, that depends on how you'd like it. Do you have an example?
By the way, we'd highly recommend going through all our training in this order:
1) Beginner Class
2) Intermediate Class
3) Template Design
4) HTML Class
5) CSS Class
6) PHP Class
Those classes will give you more than enough information to make the changes that you're wanting to make. Also, Firebug is a great tool to help speed up the process. Here's our tutorial on it:

Hope this helps! :)
Kind regards,
Nick
