CSS Variables Reference
How it works
rs-grid reads CSS custom properties from :root at mount time via
theme_from_css_vars(). Each variable maps to a field on the Theme struct.
If a variable is absent or unparseable, the light theme default is used.
Supported color formats
#rrggbb/#rrggbbaa#rgb/#rgbargb(r, g, b)rgba(r, g, b, a)—ais a 0–1 float
Color variables
Size & typography variables
Example: custom dark theme
Note
CSS variables are read once at mount time. Changing them dynamically
requires re-mounting the grid or passing an updated Theme struct
programmatically via a Leptos signal.
