1. If you haven't already done so, find the firefox browser with google and install it.
2. Then find the firebug add-on by searching for ... firebug for firefox ... and install it.
3. Using Firefox, now right click ANYWHERE on any of your pages, followed by selecting the option to inspect that element.
4. Look to your right, everything that has to do with that particular element will be shown right there.
5. For additional questions in the forum, try to stick to one single issue at a time and ask a question specific that that one issue. This is also important for other members because when you keep your questions specific to individual single items, it will at the same time help other members who are finding your posts with the search function. Example: How do I remove the space that's shown in #1 of my screenshot?
For people who are die-hard IE7 or IE8 or other browser users ... this has nothing to do with promoting Firefox, but rather, providing you with the ability to use the most helpful tool there is (firebug) when you're working on css, php, html, and other types of files. This tool only works with firebug. Besides, wouldn't you want your pages to appear correctly in the second most widely used browser too (hundreds of millions of users worldwide)?
