Checkpoint 2.1 - Mobile-PDA

Mobile devices are constrained by the time taken to download content from the server and by the size of the screen, amongst other things. Navigation that is image-based takes up valuable bandwidth and uses more screen space than similar text. In addition, maintenance tasks are much more involved where images need to be recreated to reflect any navigation change, whereas text can be easily modified.

Requirement

Navigation is text only

Recommendation

Use CSS to style text-based links for the desired visual appearance.

Checking Tool

View the page on a mobile device and verify that all navigation is text-based.
