Design and Skin Customization
If you truly want to edit your site with full control, You should clone the skin and edit the TPL and CSS exactly the way you want it.
Firebug as
@michael said will just guide you to what you should edit.
But if you are using a template that may/will be updated you either clone the skin with no fear of losing your updates
OR
Add your own css file at the end of the css file calls in the templates include.php file which you will have to add your call in that file on any update if that is modified
(Template edits should be added in the ACP if this is the case)
Eg. Your Current Skin
Edit in the skin folder the include.php file and add something like
jrCore_register_module_feature('jrCore','css','YourSkinName','myown.css');
Add that right before the
Then you can add whatever styling or overrides you want with very little effort to add one line of code (as above ) into the include if you update as the stacking order should put it last.
