Information about accessibility and the web.
Start by reading the article Accessibility and the web, focusing in particular on the Accessibility requirements and stop reading when you see the heading ARIA.
You don't have to remember everything at all. It's to help you understand the accessibility issues that are around.

Be aware of:
Vision: including blindness, low vision, colour blindness and tunnel vision
- Hearing: both total deafness and hard of hearing
- Mobility: inability to use a mouse, slow response time, limited fine motor control e.g. as a result of a stroke
- Cognitive: mental and learning difficulties e.g. inability to remember or focus on large amounts of information
- Use styles - title and heading styles
- Clarity - keep language clear and avoid jargon; ensure content is organised logically and clearly; use consistent navigation.
- Avoid using CAPITAL letters to draw attention; avoid over-using bold; don't use italics or underline.
- Don't use colour as the only way to give instructions e.g. click on the green button.
- Images need to be given a title or 'alt tag';
- Don't make text part of an image: screenreaders can't read these;
- Videos and audio need to have captions;
- Links need to be meaningful, not 'click here';the easiest way to remember is to use link-words that would be used to search for the content in a search engine!
- Avoid lots of 'inline' links i.e. links that form part of text; instead, place the links below the text, with a bullet point;
- Don't open links in a new window, unless they are a PDF or Word file;
- Add e.g. (pdf) at the end of a file link;
- Don't use full URLs, instead describe where it links to.
