Content Layout
A big mistake is to place text over backgrounds, for it makes reading difficult. Dark background colors do not make reading any easier. Studies have shown that black text on a white background is the best combination for reading and remembering. Large blocks of text should be split up into paragraphs containing 4-5 sentences. Ensure that your page contains sufficient white space, for clarity and neatness. Every page should have the same margins. There should be consistency throughout the website, so only one set of fonts, colors and layout should be used on all pages. On element that annoys most users is multiple scroll bars. Keep them at a minimum and try to avoid the side-to-side scroll bars.
