Jekyll Pure Liquid Heading Anchors

GitHub Pages can't run custom Jekyll plug-ins so when generating anchors for your headings (i.e. h1 - h6), you're stuck with JavaScript solutions that will inject anchors. But what if your users don't have JavaScript enabled on their browsers? If you're building a static website, why not make your anchors static as well? GitHub Pages doesn't support custom Jekyll plug-ins, is this plug-in whitelisted? This is all written in Liquid so need for any whitelisting. Worried about how weird or ugly a plug-in's CSS may be? These projects only generate semantically sane HTML for you to style. No need to worry about learning Ruby to edit a plug-in or getting your edits approved. It’s all Liquid, just change whatever HTML you want generated.
