Examples of font families that tend to work well on web pages are Verdana, Arial, and Geneva. Make liberal use of chunking. Large text passages on the screen can cause visual fatigue. Chunk text by making short paragraphs, using different levels of subheads, and placing bullets and block-indented paragraphs in strategic locations. Avoid using italics.
Italics are difficult to read on the screen.
Use boldface in place of italics if emphasis is required. Make use of alt tags when using graphics. Information in graphics cannot be read by screen readers unless special codes are used when placing graphic images such as photos or navigation buttons on web pages.
