Inject Stylus into shadowRoots

This userscript injects styles from the Stylus extension directly into shadowRoot instances, allowing you to style the content of web components.


How to style content inside a shadowRoot

:host

To apply styles only to the content within a shadowRoot, use the :host pseudo-selector in your Stylus styles. :host refers to the element that contains the shadowRoot (the shadow host).

/* All elements */
* {
  border: 1px violet;
}
/* Only elements inside the shadowRoot */
:host * {
  border: 1px solid mediumpurple;
}
