Web visitors love to surf, but hate to scroll. Keep your paragraphs and web pages shorter. Most people do not have the patience to scroll all the way dowwnnnn. Avoid punishing your visitors with information overload. The less work you make them do, the greater the chances they will come back to you often.
Shorter pages break the content up into easier bite-size pieces.
The Web is about Contrast. White, the absence of color in print and the combination of all colors in video, is still the best background for Web pages. If you prefer other background colors, the rule is to use colors with the highest contrast from each other. Hence, you use black type for white background. Red, the color that has sold more magazines when used in the headlines, can be used for your captions.
