## Overview

Create custom `<input type="range">` controls with `.form-range`. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only Firefox supports “filling” their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.

<Example code={`Example range
`} />

## Disabled

Add the `disabled` boolean attribute on an input to give it a grayed out appearance, remove pointer events, and prevent focusing.

<Example code={`Disabled range
`} />

## Min and max

Range inputs have implicit values for `min` and `max`—`0` and `100`, respectively. You may specify new values for those using the `min` and `max` attributes.

<Example code={`Example range
`} />

## Steps

By default, range inputs “snap” to integer values. To change this, you can specify a `step` value. In the example below, we double the number of steps by using `step="0.5"`.

<Example code={`Example range
`} />

## Output value

The value of the range input can be shown using the `output` element and a bit of JavaScript.

<Example code={`Example range

    // This is an example script, please modify as needed
    const rangeInput = document.getElementById('range4');
    const rangeOutput = document.getElementById('rangeValue');

    // Set initial value
    rangeOutput.textContent = rangeInput.value;

    rangeInput.addEventListener('input', function() {
      rangeOutput.textContent = this.value;
    });
  `} />
