    Nice tool to analyse heading structure (I use it for SEO). NFR: Currently, onClick you position clicked title on top and highlite with red border. Please position the title at least 100px or 5% below for the sake of floating headers. Thanks.

    Hello Joël, I've made the extension using standards, and that is what makes the same code (and the extension itself) compatible and available in other browsers (like Firefox). The reason is to simplify and increase compatibility (basically, one of the principles of the standards). I didn't pay attention to other browsers like Vivaldi or Brave, and I won't do it (for now, and while I do not have more time). Although those browsers announce they can use the extensions available in the Chrome store, if the extension works in Chrome and does not work on one of them, I would consider the issue is on their side, and in their announcement, so I would reach out to them and question it.

    Hi Алексей, thank you for your comment. It was removed because there are no tools, user agents, assistive technology, or any other software taking advantage of it. The algorithm was developed many years ago, when the Web was evolving to a context with more reusable content, and it was meant to generate blocks of content with their hierarchy and structure. You can read about it (check the years): * https://www.accessibility-developer-guide.com/examples/headings/html-5-outline/ * https://www.smashingmagazine.com/2011/08/html5-and-the-document-outlining-algorithm/ The extension used that algorithm to analyse the documents, helping with proper implementations. Since there was no interest in implementing the algorithm, the extension was in reality checking things against something that was neither correct nor wrong, just deprecated. Anyway, after some users contacting me to ask about it, I decided to bring it back. It is already available in other browsers, and it will be available soon on Chrome (it takes some time between uploading it to the store and its validation). Since it seems that it is being used for a purpose that was not meant for, I am not fully aware of how users are using it. If someone thinks the "HTML5 Outline algorithm" is like a valid outline for the documents, he/she might be considering things that are not the best. The outline of the document, the one used for semantics and structure, as well as for assistive technology, is mainly based on heading structure and ARIA landmarks. Those are the relevant elements to pay attention to when considering accessibility and user benefit. edit 4/14/2025: since I cannot add another comment, I edit this one. Today it was released the version that brings back the functionality.
