@material/button
Advanced tools
Buttons allow users to take actions, and make choices, with a single tap.
There are four types of buttons:
Note: Toggle buttons are implemented using the mdc-icon-button component.
For more information, see the mdc-icon-button page.
npm install @material/button
@use "@material/button/styles";
The button will work without JavaScript, but you can enhance it to have a ripple effect by instantiating MDCRipple on the root element. See MDC Ripple for details.
import {MDCRipple} from '@material/ripple';
const buttonRipple = new MDCRipple(document.querySelector('.mdc-button'));
Note: See Importing the JS component for more information on how to import JavaScript.
Material Design spec advises that touch targets should be at least 48 x 48 px. To meet this requirement, add the following to your button:
<div class="mdc-touch-target-wrapper">
<button class="mdc-button mdc-button--touch">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__touch"></span>
<span class="mdc-button__focus-ring"></span>
<span class="mdc-button__label">My Accessible Button</span>
</button>
</div>
Note: The outer mdc-touch-target-wrapper element is only necessary if you want to avoid potentially overlapping touch targets on adjacent elements (due to collapsing margins).
The mdc-button__focus-ring element ensures that a focus indicator is displayed in high contrast mode around the active/focused button.
Text buttons are typically used for less-pronounced actions, including those located in dialogs and cards. In cards, text buttons help maintain an emphasis on card content.
<button class="mdc-button">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<span class="mdc-button__label">Text Button</span>
</button>
Text button with icon example
<button class="mdc-button mdc-button--icon-leading">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<i class="material-icons mdc-button__icon" aria-hidden="true"
>bookmark</i
>
<span class="mdc-button__label">Text Button plus icon</span>
</button>
Outlined buttons are medium-emphasis buttons. They contain actions that are important, but aren’t the primary action in an app.
<button class="mdc-button mdc-button--outlined">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<span class="mdc-button__label">Outlined Button</span>
</button>
Outlined button with icon example
<button class="mdc-button mdc-button--outlined mdc-button--icon-leading">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<i class="material-icons mdc-button__icon" aria-hidden="true">bookmark</i>
<span class="mdc-button__label">Outlined Button plus Icon</span>
</button>
Contained buttons are high-emphasis, distinguished by their use of elevation and fill. They contain actions that are primary to your app.
<button class="mdc-button mdc-button--raised">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<span class="mdc-button__label">Contained Button</span>
</button>
Note: mdc-button--raised is applied for a contained button with elevation,
and mdc-button--unelevated is applied for a contained button flush with the surface.
Contained button with icon example
<button class="mdc-button mdc-button--raised mdc-button--icon-leading">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<i class="material-icons mdc-button__icon" aria-hidden="true"
>bookmark</i
>
<span class="mdc-button__label">Contained Button plus Icon</span>
</button>
Toggle buttons can be used to select from a group of choices.
There are two types of toggle buttons:
MDC Web currently does not support toggle button groups.
Icons can be used as toggle buttons when they allow selection, or deselection, of a single choice, such as marking an item as a favorite.
For more details, see the mdc-icon-button page.
We recommend using Material Icons from Google Fonts:
<head>
<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
However, you can also use SVG, Font Awesome, or any other icon library you wish.
To add an icon, add an element with the mdc-button__icon class inside the button element and set the attribute aria-hidden="true". The icon is set to 18px to meet legibility requirements.
<button class="mdc-button">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<i class="material-icons mdc-button__icon" aria-hidden="true">favorite</i>
<span class="mdc-button__label">Button</span>
</button>
It's also possible to use an SVG icon:
<button class="mdc-button">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<svg class="mdc-button__icon" aria-hidden="true" xmlns="http://www.w3.org/2000/svg" viewBox="...">
...
</svg>
<span class="mdc-button__label">Button</span>
</button>
Certain icons make more sense to appear after the button's text label rather than before. This can be accomplished by
putting the icon markup after the mdc-button__label element.
<button class="mdc-button mdc-button--icon-trailing">
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<span class="mdc-button__label">Button</span>
<i class="material-icons mdc-button__icon" aria-hidden="true">favorite</i>
</button>
Note: The mdc-button__label element is required in order for the trailing icon to be styled appropriately.
To disable a button, add the disabled attribute directly to the <button>, or set the disabled attribute on the <fieldset> containing the button.
Disabled buttons cannot be interacted with and have no visual interaction effect.
<button class="mdc-button" disabled>
<span class="mdc-button__ripple"></span>
<span class="mdc-button__focus-ring"></span>
<span class="mdc-button__label">Button</span>
</button>
The following example shows text, contained, and outlined button types with Material Theming.
Before importing any MDC Web modules, set the theme colors in your Sass file:
@use "@material/theme" with (
$primary: #FEDBD0,
$on-primary: #442C2E
);
In this case we also want to customize the label color of the text and outlined
buttons, to fulfill color contrast requirements. Assuming that you've applied
the custom-text-button and custom-outlined-button classes to your buttons:
@use "@material/button";
.custom-text-button,
.custom-outlined-button {
@include button.ink-color(#84565E);
}
If you want to customize the theme for buttons without changing the theme across the app, you can also use CSS custom properties:
@use "@material/button";
.custom-text-button,
.custom-outlined-button {
--mdc-theme-primary: #FEDBD0;
--mdc-theme-on-primary: #442C2E;
@include button.ink-color(#84565E);
}
For a more information on theming in general, see this page.
| CSS Class | Description |
|---|---|
mdc-button | Mandatory. Defaults to a text button that is flush with the surface. |
mdc-button__ripple | Mandatory. Indicates the element which shows the ripple styling. |
mdc-button--raised | Optional. Styles a contained button that is elevated above the surface. |
mdc-button--unelevated | Optional. Styles a contained button that is flush with the surface. |
mdc-button--outlined | Optional. Styles an outlined button that is flush with the surface. |
mdc-button--icon-leading | Optional. Styles a button with a leading icon. |
mdc-button--icon-trailing | Optional. Styles a button with a trailing icon. |
mdc-button__label | Recommended.* Indicates the element containing the button's text label. |
mdc-button__icon | Optional. Indicates the element containing the button's icon. |
mdc-button__focus-ring | Recommended. Indicates the element which shows the high contrast mode focus ring styling. |
Note: The mdc-button__label element is required for buttons with a trailing icon, but it is currently optional for
buttons with no icon or a leading icon. In the latter cases, it is acceptable for the text label to simply exist
directly within the mdc-button element.
However, the mdc-button__label class may become mandatory for all cases in the future so we recommend always including it.
To customize a button's color and properties, you can use the following mixins.
MDC Button uses MDC Theme's primary color by default. Use the following mixins to customize it.
| Mixin | Description |
|---|---|
filled-accessible($container-fill-color) | Sets the container fill color for a contained (raised or unelevated) button, and updates the button's ink, icon, and ripple colors to meet accessibility standards |
These mixins will override the color of the container, ink, outline or ripple. It is up to you to ensure your button meets accessibility standards.
| Mixin | Description |
|---|---|
container-fill-color($color-or-map) | If a color is passed, sets the default container fill color to the given color. If a map is passed whose keys are in the set {default, hover, focus, pressed, disabled}, sets the color in each specified state to its corresponding value. |
icon-color($color-or-map) | If a color is passed, sets the default icon color to the given color. If a map is passed whose keys are in the set {default, hover, focus, pressed, disabled}, sets the color in each specified state to its corresponding value. |
ink-color($color-or-map) | If a color is passed, sets the default ink color to the given color, and sets the icon color to the given color unless icon-color is also used. If a map is passed whose keys are in the set {default, hover, focus, pressed, disabled}, sets the color in each specified state to its corresponding value. |
density($density-scale) | Sets density scale for button. Supported density scale values (-3, -2, -1, 0). |
height($height) | Sets custom height for button. |
shape-radius($radius, $density-scale, $rtl-reflexive) | Sets rounded shape to button with given radius size. $density-scale is only required when $radius value is in percentage unit, defaults to $density-default-scale. Set $rtl-reflexive to true to flip radius values in RTL context, defaults to false. |
horizontal-padding($padding) | Sets horizontal padding to the given number. |
outline-color($color-or-map) | If a color is passed, sets the default outline color to the given color. If a map is passed whose keys are in the set {default, hover, focus, pressed, disabled}, sets the color in each specified state to its corresponding value. |
outline-width($width, $padding) | Sets the outline width to the given number (defaults to 2px) and adjusts padding accordingly. $padding is only required in cases where $horizontal-padding is also included with a custom value. |

unset is unsupported in IE. (f460e23)validateTooltipWithCaretDistances method. (3e30054)theme-styles mixin... the value being retreived from the $theme map and css property name was swapped. The mixin would request font-size/font-weight/letter-spacing from the $theme map (which expects size/weight/tracking)... so these values would always be null. (32b3913)attachTo. (05db65e)showTimeout is not set (indicating that this tooltip is about to be re-shown). (6ca8b8f)minRange param to range sliders to request a minimum gap between the two thumbs. (8fffcb5)valueToAriaValueTextFn and valueToValueIndicatorTextFn functions are called for. (b6510c8)PiperOrigin-RevId: 444830518
