The Material Components for the web slider component
@material/slider is a Material Design slider component for the web. It provides a range of features for creating sliders that are consistent with the Material Design guidelines. This package allows developers to create sliders with various configurations, including discrete and continuous sliders, and provides customization options for styling and behavior.
Basic Slider
This code sample demonstrates how to create a basic slider using the @material/slider package. The slider is initialized and an event listener is added to log the value whenever it changes.

</html>rc-slider is a React component for creating sliders. It offers a wide range of customization options and supports both single and range sliders. Compared to @material/slider, rc-slider is more focused on React applications and provides more flexibility in terms of customization and styling.
nouislider is a lightweight JavaScript range slider with full touch support. It is highly customizable and supports a wide range of features, including tooltips, pips, and more. Compared to @material/slider, nouislider is more versatile and can be used in various frameworks and environments, not just Material Design.
react-slider is a small, accessible slider component for React. It is designed to be simple and easy to use, with a focus on accessibility. Compared to @material/slider, react-slider is more lightweight and specifically tailored for React applications, making it a good choice for projects that prioritize accessibility and simplicity.
Sliders allow users to make selections from a range of values.
The MDC Slider implementation supports both single point sliders (one thumb)
and range sliders (two thumbs). It is backed by the browser
<input type="range"> element, is fully accessible, and is RTL-aware.
Contents
npm install @material/slider
@use "@material/slider/styles";
import {MDCSlider} from '@material/slider';
const slider = new MDCSlider(document.querySelector('.mdc-slider'));
Note: See Importing the JS component for more information on how to import JavaScript.
Sliders are backed by an <input> element, meaning that they are fully
accessible. Unlike the ARIA-based slider,
MDC sliders are adjustable using touch-based assistive technologies such as
TalkBack on Android.
Per the spec, ensure that the following attributes are added to the
input element(s):
value: Value representing the current value.min: Value representing the minimum allowed value.max: Value representing the maximum allowed value.aria-label or aria-labelledby: Accessible label for the slider.If the value is not user-friendly (e.g. a number to represent the day of the week), also set the following:
aria-valuetext: Set this input attribute to a string that makes the slider
value understandable, e.g. 'Monday'.aria-valuetext via the
MDCSlider#setValueToAriaValueTextFn method.There are two types of sliders:
Continuous sliders allow users to make meaningful selections that don’t require a specific value.
Note: The step size for value quantization is, by default, 1. To specify
a custom step size, provide a value for the step attribute on the input
element.
<div class="mdc-slider">
<div class="mdc-slider__track">
<div class="mdc-slider__track--inactive"></div>
<div class="mdc-slider__track--active">
<div class="mdc-slider__track--active_fill"></div>
</div>
</div>
<div class="mdc-slider__thumb">
<div class="mdc-slider__thumb-knob"></div>
<input class="mdc-slider__input" type="range" min="0" max="100" value="50" name="volume" aria-label="Continuous slider demo">
</div>
</div>
Note: By default there's no minimum distance between the two thumbs. To specify
one, provide a value for the data-min-range attribute on the root element and
adjust the min and max attributes on the input elements accordingly.
<div class="mdc-slider mdc-slider--range" data-min-range="10">
<div class="mdc-slider__track">
<div class="mdc-slider__track--inactive"></div>
<div class="mdc-slider__track--active">

</div>
</div>
<div class="mdc-slider__thumb">
<div class="mdc-slider__thumb-knob"></div>
<input class="mdc-slider__input" type="range" min="0" max="60" value="30" name="rangeStart" aria-label="Continuous range slider demo">

<input class="mdc-slider__input" type="range" min="40" max="100" value="70" name="rangeEnd" aria-label="Continuous range slider demo">
</div>
</div>
Discrete sliders display a numeric value label upon pressing the thumb, which allows a user to select an exact value.
To create a discrete slider, add the following:
mdc-slider--discrete class on the root element.mdc-slider__value-indicator-container), as shown
below.<div class="mdc-slider mdc-slider--discrete">
<div class="mdc-slider__track">
<div class="mdc-slider__track--inactive"></div>
<div class="mdc-slider__track--active">
<div class="mdc-slider__track--active_fill"></div>
</div>
</div>
<div class="mdc-slider__thumb">
<div class="mdc-slider__value-indicator-container" aria-hidden="true">
<div class="mdc-slider__value-indicator">
<span class="mdc-slider__value-indicator-text">
50
</span>
</div>
</div>
<div class="mdc-slider__thumb-knob"></div>
<input class="mdc-slider__input" type="range" min="0" max="100" value="50" name="volume" step="10" aria-label="Discrete slider demo">
</div>
</div>
Discrete sliders can optionally display tick marks. Tick marks represent predetermined values to which the user can move the slider.
To add tick marks to a discrete slider, add the following:
mdc-slider--tick-marks class on the root elementmdc-slider__tick-marks element as a child of the mdc-slider__track
elementmdc-slider__tick-mark--active and mdc-slider__tick-mark--inactive
elements as children of the mdc-slider__tick-marks element<div class="mdc-slider mdc-slider--discrete mdc-slider--tick-marks">

<input class="mdc-slider__input" type="range" min="20" max="100" value="50" step="10" name="rangeEnd" aria-label="Discrete range slider demo">
</div>
</div>
To disable a slider, add the following:
mdc-slider--disabled class on the root elementdisabled attribute on the input element<div class="mdc-slider mdc-slider--disabled">
<div class="mdc-slider__track">
<div class="mdc-slider__track--inactive"></div>
<div class="mdc-slider__track--active">
<div class="mdc-slider__track--active_fill"></div>
</div>
</div>
<div class="mdc-slider__thumb">
<div class="mdc-slider__thumb-knob"></div>
<input class="mdc-slider__input" type="range" min="0" max="100" value="50" step="10" disabled name="volume" aria-label="Disabled slider demo">
</div>
</div>
When MDCSlider is initialized, it reads the input element's min,
max, and value attributes if present, using them to set
the component's internal min, max, and value properties.
Use these attributes to initialize the slider with a custom range and values, as shown below:
<div class="mdc-slider">
<!-- ... -->
<div class="mdc-slider__thumb">
<!-- ... -->
<input class="mdc-slider__input" aria-label="Slider demo" min="0" max="100" value="75">
</div>
</div>
When MDCSlider is initialized, it updates the slider track and thumb
positions based on the internal value(s). To set the correct track and thumb
positions before component initialization, mark up the DOM as follows:
rangePercentDecimal, the active track range as a percentage of
the entire track, i.e. (valueEnd - valueStart) / (max - min).
Set transform:scaleX(<rangePercentDecimal>) as an inline style on the
mdc-slider__track--active_fill element.thumbEndPercent, the initial position of the end thumb as a
percentage of the entire track. Set left:calc(<thumbEndPercent>% - 24px)
as an inline style on the end thumb (mdc-slider__thumb) element
(or right for RTL layouts).thumbStartPercent, the initial position
of the start thumb as a percentage of the entire track. Set
left:calc(<thumbStartPercent>% - 24px) as an inline style on the
start thumb (mdc-slider__thumb) element (or right for RTL layouts).thumbStartPercent,
set left:<thumbStartPercent>% as an inline style on the
mdc-slider__track--active_fill element (or right for RTL layouts).Additionally, the MDCSlider component should be initialized with
skipInitialUIUpdate set to true.
This is an example of a range slider with internal values of
[min, max] = [0, 100] and [start, end] = [30, 70], and a minimum range of
10.

If you are using a JavaScript framework such as React or Angular, you can create a slider for your framework. Depending on your needs, you can use the Simple Approach: Wrapping MDC Web Vanilla Components, or the Advanced Approach: Using Foundations and Adapters. Please follow the instructions here.
See MDCSliderAdapter and MDCSliderFoundation for up-to-date code documentation of slider foundation API's.
