Web accessibility (WCAG)
Web accessibility means people with disabilities can use the site. The Web Content Accessibility Guidelines (WCAG) set the standard, and level AA is the usual target.
Why it matters
It widens your audience, reduces legal risk and usually makes the site clearer for everyone, including AI tools that read headings and labels.
In practice
- Check colour contrast, at least 4.5 to 1 for body text.
- Make every action work with a keyboard.
- Write real alt text and use proper headings.
