Structured, semantic markup: headings and navigation menus

HTML heading tags are used to convey the document layout. H1 tags are used for main titles, H2 tags for subtitles, and so on. Navigation menus are marked up as HTML lists. This ensures that the number of links in the list is read out at the start and it can be skipped easily.

Images

Where an image conveys important information, alternative text will be provided. If the image is used for a decorative purpose the alternative text will be left blank.

Style sheets, fonts, colours

This site uses software called Cascading Style Sheets (CSS) to control all of the presentation and layout. If your browser or browsing device does not support style sheets, the use of structured semantic markup ensures that the content of each page is still readable and clearly structured.

Font sizes and colours can be changed by using your own custom style sheets or browser settings. The BBC has an excellent guide on how to do this for various browsers and systems.
