A major feature of HTML design, and the operation of Web browsers, is that HTML code which is not understood by a browser is simply ignored, and does not cause errors during operation. By taking reasonable precautions, and following basic guidelines, you can be confident of successful display of documents by foreseeable web browser software.
Required
- Documents must conform to current specifications of HTML or XHTML. Note that documents conforming to earlier versions of the HTML specifications will automatically conform with later versions.
- Documents must contain informative text alternatives for all contextual images, in order to facilitate use by text-only Web browsers and text reader software. Remember that navigation buttons are images and need text alternatives (see Section 5 for further requirements on accessibility).
Recommended
- Individual pages, including images, should generally not be larger than 50Kb (i.e. total combined page source code plus images should not exceed this limit).
- Where possible, use cascading style sheets.
- Use meaningful document titles and page headings.
- Keep scripting (e.g. Javascript) to a minimum.
- Use a link (or links) to help the visitor to move into the site if desired, rather than back to HealthInsite.
- All link text should be underlined and a different colour from the body text. Default colours are preferred for link, activated link and visited link.
- Avoid using images as links. If images are to be used as links, include a text link next to the image as well.
- Users should be warned if a link is leading to a large file which might take a while to download.
