Standards compliance
We aim to ensure that this site complies with relevant accessibility criteria, such as the W3C Web Content Accessibility Guidelines. We will provide equivalent alternatives to auditory and visual content. We will also ensure that text and graphics are understandable when viewed without color. We will use markup and style sheets, ensuring that tags are used for main titles, tags for subtitles (and so on), with presentation being handled through the appropriate usage of stylesheets.
Visual design
We use style sheet technolog for visual layout. This is an efficient way of working that helps us to organise and update websites in the easiest way.
We ensure that the use of tables for layout is kept to a bare minimum, as evidence strongly suggests that tables are less user friendly.
We use only relative font sizes, compatible with the user-specified "text size" option in visual browsers, to help make sure the text is as easy as possible to read.
We aim to ensure that if a user has a browser that does not support stylesheets, then the content of each page should still be readable.
Image use
We aim to include textual alternatives for image content. These are known as alt tags. Using these ensures that people using screen readers who are often visually impaired are also made aware of the pages image content.
