Design for Readability
Readability and legibility are essential for all users and mandatory under WCAG 2.1 Level AA (required for UAMS compliance by April 26, 2027 – DOJ Title II ADA final rule).
Poor readability can prevent users with visual, cognitive, or motor disabilities from accessing content. Blackboard Ally for Websites flags many of these issues automatically — always fix Ally warnings before publishing.
Readability and Legibility
For people with visual impairments and disabilities, these attributes can be essential to a successful user experience. For example:
- Some people have difficulty tracking along a line of text if line-height (leading) is too wide or too narrow.
- Some people need to enlarge text and cannot access content set in small or fixed sizes.
For optimal readability (WCAG 2.1 Level AA)
- Use visual and semantic space to group related content (WCAG 1.3.1).
- Provide appropriate line height (at least 1.5 – automatically applied in the UAMS CMS).
- Use clean typography — do not override the UAMS CMS fonts.
- Avoid ALL CAPS (reduces shape recognition).
- Never underline non-link text (reserved for hyperlinks).
- Use left-aligned text for body copy (consistent left margin is easiest to read).
- Do not put two spaces after a period.
- Ensure text resizes up to 200% without loss of content or function (WCAG 1.4.4).
- Maintain sufficient color contrast (WCAG 1.4.3) and allow user-defined text spacing without breaking layout (WCAG 1.4.12).

Text Alignment
Left-aligned text is almost always the easiest to read (except for languages that read right-to-left or vertically).
- Avoid long blocks of centered text — each line starts in a different place.
- Never use fully-justified text for body paragraphs — it creates uneven spacing and “rivers of white” that harm readability (especially for cognitive disabilities). See W3C Technique G169: Aligning text on only one side.
Centered headings or short pull-quotes are acceptable exceptions.
How Blackboard Ally Helps
Ally automatically flags:
- Low contrast
- Fixed text sizes
- Poor line/paragraph spacing
- Justified text
- ALL CAPS overuse
Fix these in the page editor — most are resolved by using standard UAMS CMS blocks and not overriding styles.
