CSS Carousel with Radio Buttons
A slider driven by its dots: each dot is a radio, the track glides to its slide and the caption rises in after it lands, while the active dot stretches into a pill. No script.
Also known as: pure css slider radio buttons, css carousel without javascript, carousel dots css.

}Customizing this snippet
- Color: set
--rad-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--rad-size. Every other dimension is inem, so the whole thing scales together. Currently previewing18px. - 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.
