See also -> https://cben.github.io/sandbox/katex for using KaTeX instead of MathJax.  ### Linking to headers {#test-anchor}  Does github support [explicit header anchors](https://talk.commonmark.org/t/anchors-in-markdown/247/28)?  [link to `#test-anchor`](#test-anchor)  Does GitHub [automatically generate ids for headers](https://talk.commonmark.org/t/feature-request-automatically-generated-ids-for-headers/115/80)? Yes — [doc](https://help.github.com/articles/basic-writing-and-formatting-syntax/#section-links)   - The links have no prefix: [link to `#markdown`](#markdown)  - However the actual anchor is prefixed `id="user-content-markdown"`! [link to `#user-content-markdown`](#user-content-markdown)   Interesting, this link scrolls to a slightly different place than `#markdown`.  I'm not sure how the unprefixed `#markdown` link works at all, perhaps by JS parsing the URL?  ### Gitlab math syntaxes  inline $`\frac{kram}{down} \sum_0^\infty`$ text.
