The Art of the Fold in Web Design
I never realized how controversial it is to do web design with "the fold" in mind. Designing with the fold in mind is still vitally important. But it is not everything. If you have strong enough content and design elements that lead your readers to scroll to that content, then the fold is merely the beginning rather than the end of your audience's time on your site. Either way, responsive CMS themes can partially mitigate the effect that varying browser window sizes have on your content's display.
