Computer monitors are considerably more difficult to read from than the printed page, so it needs more clarity. If you’re writing for web, either it’s a web copy or a short article, don’t overwhelm your readers with endless lines of text. Instead, break it up into logical sections and paragraphs.
Formatting text in columns rather than lines as wide as the screen will make it easier to read. Use eye-catching headings to emphasize important points and key concepts.
