Use Appropriate Font Size
Use font sizes that are large enough to read comfortably but don't take over the page. Although there is no definitive size recommendation, the industry consensus for the main body text is at least 16 pixels (px) for websites and 12 point font for legal documents.
Use Readable Fonts
Do not use novelty fonts that may be harder to read. A trick is to avoid fonts that don't have a unique visual style between their letters, e.g., uppercase "I" versus the number "1" and a lowercase "l."
Don't Depend On Color Alone
Don't convey information through color alone. Use symbols, bold, italics and underlines to emphasize information. For example, when providing a hyperlink, make the term blue and underline it.
Have High Contrast
Use color combinations that create a strong contrast. Make sure the foreground is separate from the background. Run your product through a color contrast checker (e.g., WebAim) and correct any potential problems.
Provide Alt Text for All Images
Provide alternative text or alt text. Although captions are helpful, alt text provides a clear description of what's in the visual. This helps screen readers describe the images to visually-impaired readers and helps search engines better crawl and rank your website.
Don't clutter the page. Carefully consider where you will place visual information.
Use Scannable Hashtags
Capitalize the first word in all hashtags. For example, #LikeThis, #SoEasyToDo, #LookAtMeGo.
Name Documents Sensibly
Give documents names that make sense. Consider what a person needs and wants to know before opening the document. Name documents clearly and consistently. For example, PAVILION 508 Compliance Template.docx.
Explain Complex Images
When using complex images, try to make them simpler. Include a long description in the text below the image. This helps not only your readers with visual impairments, but all of your readers. If the description is too long, add a text link to an appendix or provide an equivalent data table below.
Make Tables Accessible
When using tables, always include a caption with the title for screen readers. Associate table data cells with their appropriately named columns and row headers. Consider using summaries if you need to explain how the table works.
Make Links Clear
Use descriptive text for links instead of "click here." For example, visit PAVILION DINFOS Online Learning.
Provide Content Warnings
Provide warnings about sensitive content. Be respectful to your audience when they're about to encounter something sensitive or potentially traumatic. Use warnings on products such as emails, social media, images, audio or video.
