Wikipedia:Accessibility dos and don'ts

This is an information page.

It is not an encyclopedic article, nor one of Wikipedia's policies or guidelines; rather, its purpose is to explain certain aspects of Wikipedia:Manual of Style/Accessibility. It may reflect differing levels of consensus and vetting.

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

Do use high contrast and color-blind friendly color schemes.
Do provide alt text and a caption for most images.
Do provide a text description of any charts or diagrams.
Do nest section headings sequentially.
Do create correctly structured tables.
Do encase non-English words or phrases in {{lang}}.
Do ask any accessibility-related questions at WikiProject Accessibility's talk page.

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.
