*background problem when screen resolution changes

[nishu12]

Well I got a website I want to code and I'm not too good in coding though I'm designing/coding websites for 2-3 years(ocassional hobby).I always tried and retried and asked and searched but I always got side effects.So I want to make this one by-the-book 100% XHTML Strict/transitional W3C Valid So I was thinking where should I start with and I thought I should start with the background.I can't seem to manage even this one. As in every single thing I ever done I can't get it to look the same in every evil screen resolution
....Enough talking.As you see in the picture it has 2 parts. the first is a gradient from blue to white(bottom to top) and the other part is a black pattern thing. How can I implement it?I can't simply adjust it's size to fit my resolution and browser.It needs to look the same for everyone.
Also while the top part can be made with a vertical 1px slice the bottom one has a pattern so it can't. i was thinking I could divide the website in 2 DIVS:main and footer and set a height percentage % like 80&20 from CSS.Use as background for main a vertical slice and a big image for the footer.But still that wouldn't fix too much ...I don't know. What would you do if it was your website?

problem is you will never get this kind of thing to look the same in every resolution your best bet it to fiddle with it untill it looks OK in every browser. my experiance is that this is a quiker method and will save you time and money trying to do somthing that it just not gunna happen
