W3 Validator Problem

May I suggest grabbing a CSS book or trying a tutorial? It will help you understand how xhtml and css works.

You have a few minor errors and a lot of inline styling, which is OK but not very easy to manage. The validator should give you some rough pointers… for example, it complains that you have a duplicate id tag… you can only have one of the same, perhaps a class would be preferable? Or do you even need an id?

You should try to put most of your styling in a stylesheet rather than in the tags inline (ie <p style=""> is inline, <p class="left-indent-para"> is easier to manage)
