LaTeX.CSS
LaTeX.css is a library that makes your website look like a LaTeX doc
...LaTeX.css is a minimal, almost class-less CSS library that makes any website look like a LaTeX document. Add any optional classes to elements with special styles (author subtitle, abstract, lemmas, theorems, etc.). The labels of theorems, definitions, lemmas and proofs can be changed to other supported languages by including the snippet provided in addition to the main CSS file. Sidenotes can be used as an alternative to footnotes, where the user does not have to jump to the bottom of the page to read it. On mobile, click the superscript to reveal the note. Add a class of left to the span with the sidenote class to make the note appear on the left side of the page on instead of right.
