HTML Heading Highlighter Extension

A chrome extension that highlights all the headings (h1-h6) on the page. I made this to extension to help me quickly get a rough idea of the heading structure when carrying out accessibility audits. Each heading is given an outline with a specific colour. A key is also appended to the body which illustrates the mapping of colour to heading.

Андрей Казаков (ID: 000000e4b63b98c5) Voted 5 ★ - Updated 09/11/2023 It's okay, it does work despite what other reviews say. It does its job, but a bit roughly: it creates an overlay on the page you're inspecting with a legend containing heading (a bit unpleasant and not-given-much-thought-to) colors that cannot be moved and it's fully opaque by default unless hovered. The huge plus (and therefore 5 stars) is that it works on SPA sites meanwhile some alternatives that highlight the headings much more elegant (I'd recommend the developer of this extension to learn from them), like "Website SEO Checker: Free Audit & Analysis", do not.
