Manual testing

There are several ways to perform manual testing for accessibility. These include visual inspection, trying out navigation with and without a keyboard, and checking page transformations and interactions. In the following paragraphs, we’ll go over each WCAG principle and provide you with a checklist of what you should look for when testing for accessibility on your webpage.
