Dark mode for your code.
By default, the popular Dracula Theme + Highlight.js make for beautifully dark code highlighting on the front-end of your WordPress-powered website. However, you can completely customize the look of code highlighting (under Appearance > Customize > Code Styles) if you like, even changing the overall design to, 🧛 *hiss*, a light mode design.
Simply activate this plugin and any code found within <pre><code>…</code></pre> tags on the front-end of your site will automatically be highlighted according to the detected language.
