The goal is to make your text inviting, readable, legible, interesting, and compelling. You just need to remember that although writing for a computer screen, and particularly for a Web site, is sometimes just like writing for paper, it's sometimes very different. Tips for Text Use upper-case text sparingly. Limit your line lengths. For text blocks, keep lines to 40-60 characters, no matter how wide the text window.
Readability decreases with lines that are too short or too long.
Remember that reading from the screen can be up to 28 percent slower than reading from paper. Choose a serif font for long passages of text. Avoid italics and underlining. They both make screen-text harder to read. Separate paragraphs with blank lines rather than with indentations.
