Description
The KaTeX WordPress plugin enables you to use the fastest TeX math typesetting engine on your WordPress website. You can include TeX inside a [katex]...[/katex] shortcode or in a Gutenberg block. Either way the math will render beautifully on your website. When using Gutenberg blocks, the equations will render immediately inside your editor!
Equations in blocks or using the [katex display=true]...[/katex] shortcode will render on page in display mode–with bigger symbols–centered on their own line.
For compatability with other LaTeX plugins, this plugin optionally supports [latex]...[/latex] shortcodes.
You can choose to serve KaTeX yourself or through the third-party jsDelivr CDN.
Screenshots

- KaTeX
Installation

katexfolder to your/wp-content/plugins/directory or automatically download and install the plugin through WordPress’s plugin manager; - Activate the plugin in WordPress; and
- Use the
[latex]shortcode or KaTeX Gutenberg blocks in your posts and pages.
FAQ-e
-
Can I move from LaTeX plugin X to this plugin?
-
You should be able to replace any other LaTeX plugin using
[latex]shortcodes without having to make changes to existing posts. Other plugins might handle display-mode latex other than[latex display=true]...[/latex], in which case old posts unfortunately have to be changed.

2.2.0

.katex-eqnode. This allows rendering KaTeX markup that is not present when the page is loaded. - Upgrade KaTeX resources to v0.13.13.

2.1.1
- Remove
<br>tags added by WordPress to shortcode output.

Previously, KaTeX Gutenberg Blocks were rendered wrapped in an unclassedspan. KaTeX shortcodes are still wrapped inside aspanwith only the classkatex-eqset. If you depend on old behavior for styling, you might need to update your styling rules.
