\KaTeX

\KaTeX is a fast and easy-to-use library that enables the rendering of mathematical notation, using LaTeX syntax.

You can use \KaTeX inline by wrapping the expression between $ or between \\( and \\).

For example, $ \sin(x) = \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n + 1)!} x^{2n + 1} $ would render: \sin(x) = \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n + 1)!} x^{2n + 1}

To display the expression on its own line and centered, wrap it around $$ or between \\[ and \\].

For example, \\[ r = \frac{\sum_{i=1}^{n}(x_i - \bar{x})(y_i - \bar{y})}{\sqrt{\sum_{i=1}^{n}(x_i - \bar{x})^2}\sqrt{\sum_{i=1}^{n}(y_i - \bar{y})^2}} \\] renders: \[ r = \frac{\sum_{i=1}^{n}(x_i - \bar{x})(y_i - \bar{y})}{\sqrt{\sum_{i=1}^{n}(x_i - \bar{x})^2}\sqrt{\sum_{i=1}^{n}(y_i - \bar{y})^2}} \]

To activate \KaTeX for a post, include katex = true within the [extra] section of the post's front matter. For exemple:

+++
title = "Testing KaTeX"
date = 2002-11-30

[extra]
katex = true
+++

You may enable it globally as well, by setting katex = true in the [extra] section of your config.toml.

For enhanced performance and security, the \KaTeX JavaScript, CSS, and fonts are hosted locally.

Note: After enabling \KaTeX, if you want to use $ without rendering a mathematical expression, escape it with a single backslash: \$.

Table

Here's an example of a table¹. Its colours change depending on the current theme.

Symbol	Element	Atomic Number
H	Hydrogen	1
C	Carbon	6
Fe	Iron	26
Au	Gold	79

Code Block

fn main() {
    println!("Hello, world!") -> ();
}
