Questions tagged [katex]

KaTeX is a Javascript-based math rendering library for the web. It allows LaTeX commands as input which are then rendered similar to the way LaTeX itself does it. Note that questions dealing with installation of KaTeX, how it works, or rendering problems are widely considered to be off topic and are at risk of being closed. These questions can be asked on Stack Overflow (https://stackoverflow.com) instead.
