If you're just setting margin-top on the CSS class 'element-column-right-alpha-outer', then you shouldn't need any hacks. I suspect that you're running into an issue with differences in the default margin or line-height in Chrome and the other browsers for the top-most element in the 'element-column-right-alpha-outer' container. Try Eric Meyer's CSS Reset file that initializes all HTML elements. It will probably mean you'll need to make some changes, but you should ultimately find that you're getting better cross-browser behavior.
