Question - How do you show which page you're on (in a menu)?
Answer -
If PHP is not available to you, you could use the cascade. Put an id in your body tags and an id in each of your 'a' tags for the links.
Let's say on page one you have this:
CSS
....
page one
...
In your CSS, you can have something like this:
CSS
#page1 a#page1link {
color:purple;
