How do I have no borders in 6.1.1

Hello all. I'm trying to find the css file in 6.1.1 that lets me loose the borders on my profile page. Which file is it? I know it's something simple.

Do you use Firefox browser?  If so, download a plugin called Firebug.  It allows you to easily figure out which css file is controlling the elements in your browser window.  It has allowed me to make many many design changes on my site very easily.

Edit the CSS files. Mainly the file templates/tmpl_xxx/css/general.css
