Wikipedia:Accessibility dos and don'ts

All users, regardless of disability, should be able to read, navigate, and contribute to Wikipedia easily. Therefore, when editing articles:

Don't impede the ability to distinguish links from regular text.
Don't use scrolling lists or collapsible sections to conceal content. (See exceptions in the Manual of Style).
Don't use color as the only means of conveying information.
Don't use tables for layout—use <div> blocks instead.
Don't leave blank lines between list items.
Don't use Unicode characters as icons or images.
Don't sandwich text between two images, and don't use fixed image sizes unless absolutely necessary.
