Accesibility

08 September 2017

Web Accessibility means that a web site can be used by people of all abilities and disabilities.

In particular a website, accessibility depends on how a person's disability affects the way they perceive information on a page and how they navigate within and between pages.

Some key elements that affect accessibility include:

For people who can't see very well - the colours and the contrast between colours, the size of text and the choice of fonts.

For people who are blind - how a screen reader interprets the elements on a page such as alt tags for images and title tags for links.

For people who can't hear very well - how any audio content is represented graphically such as subtitles or signing on video content

For people who find a keyboard or mouse hard to use - the ease with which someone can navigate to parts of the page.

For people who find words difficult - the length of sentences and paragraphs, the vocabulary used, the choice of fonts and size of text, the opportunity to have text read out loud.
