The mmenu.js plugin uses CSS variables for most of its sizing and styling. The default CSS variables can be overridden to customize your menu without having to make changes to the plugin.

    .mm-menu {
        --mm-listitem-size: 56px;

Because CSS variables are cascading, they can be overriden for each part of the menu. Learn how to do so in the CSS variables tutorial.

Note that add-ons might have their own set of CSS and SCSS variables.
