In addition Bobby will give a calculated download time for your page, itemising all the elements on it. Ensure your layout makes sense when read in this way.
Accessibility can be about download times as well as complexity.
Minimise use of graphics - those that are used should be optimised and compressed so the download time is as short as possible Avoid setting absolute font faces and font sizes on web pages. If you use frames in your website, make sure you have a fully functioning noframes version giving access to all the information. Users of access technologies usually cannot use frame-based sites at all, so telling them to upgrade their browser is annoying. DISinHE is a JISC-funded service that offers information on a wide range of issues, including how to make information technologies more accessible. In addition, information contained within proprietary file formats such as Flash files will not be indexed by web indexing robots.
