Segmented Bar
iOS-style segmented control with sliding pill background — sibling-position selectors drive the pill via translateX, no JS required.
Segmented Bar the 9th of 18 designs in the 18 CSS Radio Button Designs collection. The design is implemented in pure CSS — no JavaScript required. Copy the HTML and CSS panels below into your project. Because the demo is pure CSS, it works in any framework or templating engine you happen to use. The design honours prefers-reduced-motion and uses real semantic markup, so it ships accessibility-ready out of the box.
