Angular Material buttons are native <button> or <a> elements enhanced with Material Design
styling and ink ripples.
Native <button> and <a> elements are always used in order to provide the most straightforward
and accessible experience for users. A <button> element should be used whenever some action
is performed. An <a> element should be used whenever the user will navigate to another view.
There are several button variants, each applied as an attribute:
| Attribute | Description |
|---|---|
mat-button |
Rectangular text button w/ no elevation |
mat-raised-button |
Rectangular contained button w/ elevation |
mat-flat-button |
Rectangular contained button w/ no elevation |
mat-stroked-button |
Rectangular outlined button w/ no elevation |
mat-icon-button |
Circular button with a transparent background, meant to contain an icon |
mat-fab |
Circular button w/ elevation, defaults to theme's accent color |
mat-mini-fab |
Same as mat-fab but smaller |
Buttons can be colored in terms of the current theme using the color property to set the
background color to primary, accent, or warn.
According to the Material design spec button text has to be capitalized, however we have opted not
to capitalize buttons automatically via text-transform: uppercase, because it can cause issues in
certain locales. It is also worth noting that using ALL CAPS in the text itself causes issues for
screen-readers, which will read the text character-by-character. We leave the decision of how to
approach this to the consuming app.
Traditional fab buttons are circular and only have space for a single icon. However, you can add the
extended attribute to allow the fab to expand into a rounded rectangle shape with space for a text
label in addition to the icon. Only full sized fabs support the extended attribute, mini fabs do
not.
<button mat-fab extended>
<mat-icon>home</mat-icon>

</button>Angular Material uses native <button> and <a> elements to ensure an accessible experience by
default. A <button> element should be used for any interaction that performs an action on the
current page. An <a> element should be used for any interaction that navigates to another
URL. All standard accessibility best practices for buttons and anchors apply to MatButton.
MatAnchor supports disabling an anchor in addition to the features provided by the native
<a> element. When you disable an anchor, the component sets aria-disabled="true" and
tabindex="-1". Always test disabled anchors in your application to ensure compatibility
with any assistive technology your application supports.
Buttons or links containing only icons (such as mat-fab, mat-mini-fab, and mat-icon-button)
should be given a meaningful label via aria-label or aria-labelledby. See the documentation
for MatIcon for more
information on using icons in buttons.
See the documentation for MatButtonToggle
for information on stateful toggle buttons.
