To style the range input with CSS you’ll need to apply styles to two pseudo-elements: ::-webkit-slider-thumb and ::-webkit-slider-runnable-track. Find out how you can apply custom styling and make the range input more functional and appealing.

The input element with a type of range is a native HTML form UI element that allows users to select a value by dragging a slider over a range field.

The default browser styling for this element is very basic and doesn’t provide enough information to the user which might confuse one. Also, the appearance of the range input element is different across browsers.

Luckily there are ways you can improve that using nothing but native CSS and JavaScript.

CSS selectors for the range input

The range input widget consists of two parts the thumb and the track. Each one of these parts has its own pseudo-class selector for styling with a vendor suffix for cross-browser support.

Thumb:

input[type=”range”]::-webkit-slider-thumb

input[type=”range”]::-moz-range-thumb

input[type=”range”]::-ms-thumb

Track:

input[type=”range”]::-webkit-slider-runnable-track

input[type=”range”]::-moz-range-track

input[type=”range”]::-ms-track

input[type="range"] {
  -webkit-appearance: none;
  margin-right: 15px;
  width: 200px;
  height: 7px;
  background: rgba(255, 255, 255, 0.6);
  border-radius: 5px;
  background-image: linear-gradient(#ff4500, #ff4500);
  background-size: 70% 100%;
  background-repeat: no-repeat;
}

input[type="range"]::-webkit-slider-thumb {
  -webkit-appearance: none;
  height: 20px;
  width: 20px;
  border-radius: 50%;
  background: #ff4500;
  cursor: ew-resize;
  box-shadow: 0 0 2px 0 #555;
  transition: background .3s ease-in-out;
}

input[type=range]::-webkit-slider-runnable-track  {
  -webkit-appearance: none;
  box-shadow: none;
  border: none;
  background: transparent;
}

To indicate the selected value, we can add a color from the start of the track up until the thumb. To do that we can use the background-image property with the linear-gradient() value. The background-size property will be used to set the size, which can later be updated with JavaScript.

Improving usability

The default range input doesn’t specify any values selected. Which makes it hard for users to understand what value is currently selected.

While the hash marks and labels on the range input are a great way to aid users visually, this feature is yet to become available.

However, there are a few ways you can improve that with some additional HTML and JavaScript:

1. Specify the output element to display the selected value
2. Specify the number input that is synced to the range input

Specify the output element to display the selected value

The output element on the side of the range input will display the selected value. You’ll have to add an id attribute for the output element, and an oninput attribute for the range input with a short function as a value, that will update the output element contents.

<input type="range" min="0" max="100" oninput="rangevalue.value=value"/>
<output id="rangevalue">50</output>

Specify the number input that is synced to the range input

To take it a step further you can add a number input next to the range element.

That way the user will see the selected value and will have an option to modify it via the number input, which can be a better experience especially for mobile users.

<input type="range" value="50" min="0" max="100" id="range" oninput="rangevalue.value=value"/>
<input type="number" id="rangevalue" value="50" oninput="range.value=value">

A sprinkle of JavaScript

To finalize we’ll need some JavaScript code to make it all work. The oninput attribute is already updating value based on a target element.

But to update the selected area of the range input we need to calculate the ratio and apply that value to the input background-size property.

const rangeInputs = document.querySelectorAll('input[type="range"]')
const numberInput = document.querySelector('input[type="number"]')

function handleInputChange(e) {
  let target = e.target
  if (e.target.type !== 'range') {
    target = document.getElementById('range')
  } 
  const min = target.min
  const max = target.max
  const val = target.value
  
  target.style.backgroundSize = (val - min) * 100 / (max - min) + '% 100%'
}

rangeInputs.forEach(input => {
  input.addEventListener('input', handleInputChange)
})

numberInput.addEventListener('input', handleInputChange)
