Planning a website is not an easy task, indeed. At the first stage, you have a pen and a paper and everything goes pretty smooth. Then you sit down before a computer, open your designing/prototyping software (Photoshop, Fireworks, Balsamiq Mockups, MS Word...) and start implementing your layout in a real internet world dimensions. And then ‘BAM’ ... you understand, that a lot of important elements aren’t above the fold and there is no free space above the fold and if you will put everything above the fold what’s about principles of ‘White space is the King” and “Make your design clear”? What to do? Of course you’re concerned, because you heard a lot about the critical FOLD space and even your client’s marketer knows this word and he is insisting that their ad block and company mission and navigation and featured content section and quick links and search box and and and bla bla bla to be placed above the fold.
