Forum accessibility: make your community usable for everyone

Many people use screen readers, keyboard-only navigation, magnification or captions. An accessible forum is easier for everyone, including people on phones and older members.

Key takeaways

WCAG is the main international standard for web accessibility.
Your theme choice makes the biggest difference: contrast, focus outlines, labeled buttons.
Encourage members to add alt text and captions; set an example in staff posts.

The standard: WCAG

The Web Content Accessibility Guidelines (WCAG) from the W3C are organized around four principles: content should be perceivable, operable, understandable and robust. See the W3C: WCAG overview and the W3C: Introduction to web accessibility.

Theme and layout checklist

Color contrast: body text and links must stand out from the background. Avoid light gray text.
Don't rely on color alone, for example for unread markers; add an icon or text.
Keyboard navigation: tab through your forum. Can you reach the login, reply and menu buttons? Is the focus outline visible?
Labeled controls: icon-only buttons need text labels for screen readers.
Responsive design and text that can be zoomed to 200% without breaking.
Headings and landmarks so screen reader users can jump around.

Content checklist

Add alt text to images in announcements and guides.
Use captions or transcripts on video posts when possible.
Write descriptive link text ("download the backup guide," not "click here").
Avoid walls of text: short paragraphs, lists and headings.
Avoid flashing animated GIFs in signatures.

Test it

Run a free automated checker on your main pages (it catches some issues, not all).
Try your forum with your device's built-in screen reader.
Ask members who use assistive technology for feedback.
