Notice barriers. Check them. Keep improving.
Start with an everyday task, investigate what gets in the way, and try it again after making changes.
Read the evidence in context
Check the source, scope and date of statements or certification records to understand which pages or services they describe.
Try the task yourself
Choose a task such as signing in or completing a form. Combine scans, keyboard checks and assistive technology testing to see whether people can complete it.
Review after changes
Repeat the same task after a fix. Keep checks and user reports part of maintenance as your content and features change.
You do not need every tool
Choose the tool that fits your task. Badges and tool results are clues for improvement, not a complete audit or a guarantee of conformance.
Explore accessibility with a small exercise
Choose a topic—keyboard use, images, contrast or accessibility statements—and follow a practical guide. You do not need to learn every standard first.
Try keyboard navigation
Tab through links and buttons. Can you see where you are, use each control and move on? Follow the guide for keyboard checks and safe form testing.
