Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension is using the HTML5 outline algorithm to create a table of contents.

Should also work well with HTML4 (and older?) pages, that have structured headings.

The table of contents is clickable and tries to highlight the heading/section in question after the jump.

The extension should prove useful to people who find themselves often using online HTML5 outliners.

Comments, bug reports and suggestions much appreciated!

Doesn't work, the icon didn't show up on a page that clearly had HTML5 structure. Looking for an alternative :(

It incorrectly shows <h1> - <h6> elements as sections of the outline, which in HTML5, they aren't. If you have this code: <section> <h1>First heading 1</h1> <h1>Second heading 1</h1> <h2>First heading 2</h2> </section> You get an outline of: 1. First heading 1 2. Second heading 1 1. First heading 2 When you should get an outline of: 1. First heading 1 In an HTML5 document outline, its the sectioning elements of: section, article, nav and aside that create the sections, not the <h1> - <h6> elements, which were responsible for doing that in HTML 4 & XHTML 1.0. So, the extension is using both sets of elements to create HTML5 outlines, when it shouldn't.
