Distinguish between a contents list for a page, links to other pages, and links to other sites. Do not change default link colours and style, otherwise users will not recognise the links. Give sizes of files which can be downloaded. The wording of links embedded in text should help users scan the contents of a page, and give prominence to links to key pages. This should establish the site identity and give a clear overview of the content.
Graphics add interest but are slow to load and can impede navigation.
Use the minimum number of colours to reduce the size of graphics. Use the ALT tag to describe graphics, as many users do not wait for graphics to load. Make text easy to read Never use flashing or animation, as users find this very distracting. Avoid patterned backgrounds, as these make text difficult to read. Support different browser environments Use a maximum 640 pixel width, or 560 pixels for pages to be printed in portrait mode.
