Re: Page Margains?
With BV you won't get an EXACT fit from left to right on ALL pc's. But what you can do is get it as wide as possible for less white margins either side on most pc's but probably not 'widescreens'.
If you build your site at no more than 1000 wide (personally i recommend 940-980 max, then there will be only a very very limited amount of users, those still on 800 x 600 screen resolution that may have to scroll sidewards.
If you want 100% then stick to 800 wide, but I think you'll find most here will reccommend going wider now.
Don't aim for success if you want it; just do what you love and believe in, and it will come naturally.
