Liquid Glass Switch
An iOS 26 style switch on a frosted settings row. Hover or press and the white thumb swells into a clear glass lens that bends the track under it. A real checkbox, so it works with keys and forms.
Also known as: liquid glass toggle css, ios 26 toggle switch css, liquid glass switch css.

}Customizing this snippet
- Color: set
--gls-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--gls-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
