Zero-JS readout

CSS reads the thumb position through a view-timeline: a live readout with no JavaScript at all.

How to play

Drag; the number is computed by CSS alone.

Keyboard

Tab to the slider, then ← → to step, PgUp PgDn to jump, Home End for the ends.

Under the surface

A native range input is the real control: it owns the value, the keyboard and what screen readers hear. Everything you see is drawn from it.

What it needs

No libraries, just HTML, CSS and JavaScript

The concept

What Zero-JS readout really is.

A live readout with no JavaScript: CSS reads the thumb position through a scroll-driven timeline. It shows how far the platform can go.

Where to use it

5 real-world places this slider fits, from product UIs to marketing pages.

  1. 01

    Performance-critical pages

    Controls that work before or without JavaScript.

  2. 02

    Email-like static pages

    Lightweight interactive widgets with minimal code.

  3. 03

    CSS showcases

    Demonstrating modern CSS to developers.

  4. 04

    Design systems

    A progressive-enhancement reference component.

  5. 05

    Low-power devices

    Fewer scripts for kiosks and old phones.

Implementation

The source, ready to copy.

Two files and a small shared scaffold. Copy them, or take the whole package.

Naked Number

No thumb: the number itself is the handle. Digits roll like an odometer, it stretches with speed, and you can type into it.

Grab the number and drag it; click it to type; Shift and Alt change the stepExplore Naked Number →

Ratchet

A brass knob on a toothed rack. It resists between notches, then drops in with a click, a flick of the pawl and a pulse of vibration.

Drag the knob; it resists, then clicks into the next notchExplore Ratchet →
