## 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.

## 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"`.

## Output value
The value of the range input can be shown using the `output` element and a bit of JavaScript.
<Example code={`<label for="customRange4" class="form-label">Example range</label>
<input type="range" class="form-range" min="0" max="100" value="50" id="customRange4">
<output for="customRange4" id="rangeValue"></output>
<script>
// This is an example script, please modify as needed
const rangeInput = document.getElementById('customRange4');
const rangeOutput = document.getElementById('rangeValue');
// Set initial value
rangeOutput.textContent = rangeInput.value;
rangeInput.addEventListener('input', function() {
rangeOutput.textContent = this.value;
});
</script>`} />
