The long answer (to learn how to do it in the future):
– Download and start using Firefox: http://www.mozilla.com/?from=sfx&uid=266924&t=318
– Get the Firebug add-on for Firefox: https://addons.mozilla.org/en-US/firefox/addon/1843/
– Restart Firefox
– You can now dive into your code very easily; viewing your site’s front-end in Firefox find the little bug icon and click on it; the Firebug panel will now open; click the blue arrow in which you can now hover over any item on your page to find more info about the code and even test in real time CSS changes for example
– Unless you intend on always having a webmaster take care of it which it doesn’t look that way as you seem to have taken initiative with your website you should always be learning;
