The KaTeX WordPress plugin enables you to use the fastest <a href="https://github.com/Khan/KaTeX" rel="nofollow ugc">TeX math typesetting engine</a> on your WordPress website. You can include TeX inside a <code>[katex]...[/katex]</code> 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 <code>[katex display=true]...[/katex]</code> shortcode will render on page in display mode–with bigger symbols–centered on their own line.
For compatibility with other LaTeX plugins, this plugin optionally supports <code>[latex]...[/latex]</code> shortcodes.

The KaTeX WordPress plugin integrates the super-fast <a href="https://github.com/Khan/KaTeX" rel="nofollow ugc">KaTeX math typesetting engine</a> with your WordPress website. The plugin allows you to put LaTeX in a <code>[latex]...[/latex]</code> shortcode, and beautiful math appears on your post or page.
The plugin also has an option to use the excellent <a href="http://www.jsdelivr.com" rel="nofollow ugc">jsDelivr CDN</a> to load the KaTeX scripts, further increasing the performance of the plugin.
Equations in <code>[latex display="true"]...[/latex]</code> will be rendered in display mode (rather than inline mode) and centered on its own line.
