Checka11y.css
Checka11y.css is a lightweight CSS library designed to help developers identify accessibility issues during the development phase. By importing the stylesheet, common errors such as missing alt attributes, invalid HTML nesting, and autoplay media are visually highlighted on the page. It serves as a quick, initial diagnostic tool before using more complex automated scanners. It is intended for local development environments only and should not be deployed to production.
