Make the site accessible to any web browser, including text and speech browsers. Beware of the 'latest is greatest'. This seriously affects accessibility. No italic, extra-bold or condensed. No colour used as a unique functionality characteristic.
Long pages have a link partway through to the top of the document.
Sufficient contrast between graphic elements. Page title is sensible and provides substantive information. Do not bar user settings for style sheets and scripts. Bear in mind that the visitor may have certain functions turned off, such as image loading, background, style sheets, video, sound, blinking, Applets, frames, automatic browsing etc. If neccessary, hyperlink with enlargement, clarification, additional explanation.
