Add alt text to images – Alt text provides a written description of an image for individuals who cannot see them. They can be picked up by people using screen readers or Braille output devices.
Headings – Use headings to break down the content on your page into manageable chunks. This will help non-visual users to understand how the page is organised as well as making it simpler for screen reader users to navigate.
Use a color contrast checker – Check that your foreground and background colours have adequate contrast by using a Colour Contrast Analyser
Avoid using tiny fonts – Even though modern browsers can increase text size automatically, some users may be unaware that font size can be increase. If you use a reasonably large font size by default then your website will be more accessible by default.
Simple Language – Keep your language simple and sentences short to read.
White space is important – As with print, space between lines and columns of text help users follow the flow of the text. Good white space contributes to a cleaner and better experience for all users and in e-commerce can help lead to higher sales.
Provide a focus – You website should respond to mouse movements for instance, colour changes when a mouse moves over link text. For people who aren’t using a mouse, provide the same functionality when navigation with a keyboard.
Avoid using pictures of text – Pictures of text can not be read by screen readers and become blurry when enlarged. As with print avoid overlaying text on images.
