Writing Mode

Overview

The writing-mode CSS property sets whether lines of text are laid out horizontally or vertically, as well as the direction in which blocks progress. When set for an entire document, it should be set on the root element (html element for HTML documents).

<div class="writing-mode:horizontal-tb">
    <p class="f:blue-60! ...">
        Writing Mode
    </p>
    <p class="...">
        Virtual CSS
    </p>
</div>

Master supports native CSS variables and functions, just add var(--key) or use shorthand$(key) for variables.
