En Using the browser console for accessibility testing se explica cómo se puede usar la consola de JavaScript para analizar la accesibilidad de una página web.
Un ejemplo sencillo:
Here’s a simple script you can try first. It shows every link on the page as a NodeList in the console, which is useful for quick checks.
document.querySelectorAll(«a»);
Or you could highlight all links on the page:
document.querySelectorAll(«a»).forEach(a => a.style.outline = «2px solid red»);
Some people turn snippets like these into bookmarklets (small saved JavaScript actions). That can be useful, but for teaching and quick testing, the console is often easier. I explain why at the end of the article.
