A Lancaster University Resource for Students and Staff
This page lists some essential guidelines. If you implement them on your webpages, they should be accessible and standards compliant.
The WAI has produced 10 Quick Tips. Adherence to these rules will help your webpages reach Checkpoint 1. The points below are explained in further detail at: http://www.lancs.ac.uk/fss/resources/access/tips
1. Images and Animations
Make sure each image has an <alt> attribute to describe its function. This appears as a yellow flag description. Users who switch off the images will be able to see what is important.
2. Image Maps
Best to avoid as can provide access problems. Provide text alternatives for disabled users. Use client-side MAP and text for hotspots.
Provide captioning and transcripts of audio, and descriptions of video.
4. Hypertext links
Use text that makes sense when read out of context. For example, avoid "click here". People expect links to be blue and underlined.
5. Page organisation
Use headings, lists, and consistent structure. Use CSS for layout and style where possible.
6. Graphs & charts
7. Scripts, applets & plug-ins
Use NOFRAMES and meaningful titles.
Make line-by-line reading sensible. Summarize. Data tables should have the headings marked.
10. Check your work
Validate. Use tools, checklist and guidelines at http://www.w3.org/TR/WCAG
1. Doctype statement
Always include a doctype statement. It must be present on every page of the website. Make sure you are aware of the deprecated elements and attributes and use the W3C's on-line validator to check your pages.
2. Define the natural language
Define the natural language as English to assist screen readers by altering
the <HTML> tag as shown:
Show any subsequent language changes.
3. Define scripts
Define scripts correctly e.g.
4. Deprecated HTML code
5. Drop-down menus
6. New browser windows
Avoid opening new browser windows unless essential. This breaks the browser back button making it harder for disabled users to navigate backwards. Warn your users if a new window is going to open. Contact web support staff for assistance.
