Math typesetting using KaTeX

Stack has built-in support for math typesetting using KaTeX.

It’s not enabled by default side-wide, but you can enable it for individual posts by adding math: true to the front matter. Or you can enable it side-wide by adding math = true to the params.article section in config.toml.

Inline math

This is an inline mathematical expression: $\varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887…$
