Editing Profile tabs?

[Xexiu]

Thank you for the info, Lynne!

I allready knewed about that. But it isn't what I'm looking for.
Let me explain myself. I want to edit the code and add my own CSS. For example:

I want to delete:

<ul class="tab_list" style="height: 29px;">

And add:

<ul style="my_code_here">

This is just an example. I want to know where I can find ALL the code that makes the tab function in order to edit it and remove some thing that I don't like. In Memberinfo template is only this:

<div id="profile_tabs" style="padding-top: 20px;">
                    $template_hook[profile_left_first]
                    $blocks[visitor_messaging]
                    $blocks[aboutme]
                    $blocks[stats]
                    $blocks[friends]
                    $blocks[infractions]
                    $blocks[contactinfo]
                    $template_hook[profile_left_last]
                </div>

Is there anyway to edit the "entire" code?

Much thanks and apreciated for your answers!
