Moreover, Metro UI contains the m4q module, which provides the user with most of jQuery's functionality for interacting with the DOM.

CSS <Vars>

Metro UI is evolving with each release to better utilize CSS variables for global theme styles, individual components, and even utilities.
Metro UI provide dozens of variables for colors, font styles, and more at a :root level for use anywhere. Variables are divided into global and component variables.

Variables names start with the component name and are followed by the name of the property.

    :root {
        --body-background: #ffffff;
        --body-color: #191919;
        --border-color: #e8e8e8;
        --link-color: #5a87cb;
        --link-color-hover: #0056B3FF; 
All Metro UI components support dark ↔ light mode. In Metro UI light mode is default. For dark mode you can define variables inside a .dark-side class.

To switch to dark mode you must add class .dark-side to html tag. Also you can use special components that switch mode.

    .dark-side {
        --body-background: #1e1f22;
        --body-color: #dbdfe7;
        --border-color: #4a4d51;
        --link-color: #5a87cb;
        --link-color-hover: #0056B3FF;
You can override css variables not only in the :root. If you only need to change one or more components on a page or component(s) in specified area, add your own class to the component (area) and define variables inside that class. More information you can get from documentation.
