Styling

The components follow the same styling contract as the other wms-utils products: a theme attribute, public CSS custom properties (--sl-*) and public parts. A page that themes one product can theme the others with the same base names (accent, bg, panel, text, muted, border, danger, radius, font).

Light, dark and auto#

Every component takes theme="light" (the default), theme="dark" or theme="auto", which follows the user's system setting (prefers-color-scheme).

html

<slotting-station wave-id="WAVE-0815" theme="auto"></slotting-station>

Custom properties#

Set them on the elements or on any ancestor; they inherit into the shadow roots. A value you set wins over the theme's default in both light and dark mode, so set dark values inside your own dark-mode selector if you need both. The derived colours (soft tints, bin states) default to mixes of the base colours, so they follow your palette when you change only --sl-accent, --sl-panel and friends.

The TRIAL mark has fixed colours on purpose and can't be themed.

Content-Security-Policy#

The components inject nothing into your page's document. Their styles are constructed stylesheets inside their shadow roots, they set no style="" attributes and build no code from strings, so they work under style-src 'self' and script-src without 'unsafe-inline' or 'unsafe-eval'.
