CSS - Is This Browser Or Coding Bug?

With my limited knowledge of css, html, etc.
I can mold my page to look just the way I desire on my given screen size (1280x1024) and browser (mozilla) but can not seem to get a fix for all variables (1024x768, etc.).

I've tried containing divs & percents and a few other solutions to no avail. Just want to know if you guys know any quickfix or a recommended strategy in tackling this issue going further.

id post code here, but the site wont allow it due to external links.
so please check it out here and let me know

http://needaputer.com
css is at same url just located at .com /css/styles.css

my goal:
-- auto center content on page horizontally - (based on screen size - cross browser compatible)
-- make sure header and footers are absolute top and bottom of page always (based on page size and cross-browser compatible)
-- toggle "page zoom" for entire page via buttons (if needed and possible to adjust content for each screen size)

I've tried to insert a horizontal drop down CSS menu in my layout. However, the menu bar displays about 10 pixels lower in Firefox than it does in IE.

<a href="(URL address blocked: See forum rules)">Link</a>

I checked the margins, padding but can not seem to find a way to get the menu to display at the same position in both browsers.

Any guidance is very appreciated. thanks.

My first post.... ok... First I would like to say THANK YOU to anyone who has time to bestow some knowledge to me on what I am sure is a highly noob-esqe situation. I would also like to say that I have thoroughly search this and other forums for my issue, unfortunately I dont think I understand CSS or any web design enough to comprehend the solutions given. I think this may require someone with the knowledge I lack to come down to my level... if you can bend that low.. and walk me thru layman term-style. Again thanks in advance for anytime spent helping out.

That being said

I was recently trying to jazz up my website that is hosted by a certain music community. I do a decent amount of business thru this site so I wanted to step up the interface a little and get away from using the standard page setup they give you. They do offer the option to edit CSS to construct your own for a little more customization. I jumped in, and after a few days of struggling, I got it looking how I wanted it. I was excited until I realized it looked different on almost every computer i visited the site on. My Background is fine, but the links to paypal and other content is all over the place(e.g. song player, twitter link, buttons) I have tweaked and tweaked, but have not been able to remedy this apparently common problem due to my lack of knowledge and experience. My only hope is to post the coding here and have a Smart Guy/Girl guide me in the right direction. I hope Im not asking too much guys... here goes

(I know I can post my url here, how can I redirect you guys to veiw my site??)

Hi

I am in the early stages of designing this site http://www.boostnowbreaks.co.uk/test/

This gives you a general idea of how the site should look http://www.boostnowbreaks.co.uk/test.jpg

When i view my CSS site in Opera the site completely breaks, this is true for IE5 as well.

Would someone mind having a look at my code and advise me where I am going wrong?, also have I gone about the structure in the right way?

Much appreciated for any help on this!
