- Avoid the words "click here" (see Writing for the Web); use descriptive text within sentences or headings as the anchor for hyperlinks.
Examples of proper use of "click here" are: "Click here to listen to the real audio file" or "Click here for more information on services to children."
- Avoid underlining any text that's not a hyperlink.
- Never style text as the same color as your chosen hyperlink colors.
- Don't use the default “blue” color for non-hyperlink text.
- Avoid yellow, blue, and green in close proximity. Those with visual impairment find it harder to distinguish these three colors.
ALT Text and Text Equivalents
- Provide a text equivalent for every non-text element
(e.g. “alt”, “longdesc”, or a caption for an image or graphic).
- Keep your ALT text to less than 50 characters.
- ALT text should provide the same meaningful information to non-visual users as received by visual users.
- Consider what the page looks like when images are not shown. Then, write for each image an ALT text that best works as a replacement.
