What is @material/fab?
@material/fab is a Material Design implementation of the Floating Action Button (FAB) component. It provides a way to create floating action buttons that adhere to Material Design guidelines, offering a consistent and visually appealing user experience.
What are @material/fab's main functionalities?
Basic Floating Action Button
This code creates a basic floating action button with a 'favorite' icon. The button uses the 'mdc-fab' class to apply the Material Design styles.
<button class="mdc-fab" aria-label="Favorite">
<span class="mdc-fab__icon material-icons">favorite</span>
</button>
Mini Floating Action Button
This code creates a mini floating action button with an 'edit' icon. The 'mdc-fab--mini' class makes the button smaller than the standard FAB.
<button class="mdc-fab mdc-fab--mini" aria-label="Edit">
<span class="mdc-fab__icon material-icons">edit</span>
</button>
Extended Floating Action Button
This code creates an extended floating action button with an 'add' icon and a label. The 'mdc-fab--extended' class makes the button wider to accommodate the label.
<button class="mdc-fab mdc-fab--extended">
<span class="mdc-fab__icon material-icons">add</span>
<span class="mdc-fab__label">Add</span>
</button>

Design & API Documentation
Installation
npm install --save @material/fab
Usage
The demonstrations use the Material Design Icon Font.
You may include this to use them as shown or use any other icon method you wish.
Default
<button class="mdc-fab material-icons" aria-label="Favorite">
<span class="mdc-fab__icon">
favorite
</span>
</button>
Mini
<button class="mdc-fab mdc-fab--mini material-icons" aria-label="Favorite">
<span class="mdc-fab__icon">
favorite
</span>
</button>
Plain
<button class="mdc-fab mdc-fab--plain material-icons" aria-label="favorite">
<span class="mdc-fab__icon">
favorite
</span>
</button>
Absolutely positioned
By default the FAB rests in the page where it sits in the content flow.
Developers must position it as-needed within their applications designs.
<style>
.app-fab--absolute.app-fab--absolute {
position: fixed;
bottom: 1rem;
right: 1rem;
}
@media(min-width: 1024px) {
.app-fab--absolute.app-fab--absolute {
bottom: 1.5rem;
right: 1.5rem;
}
}
</style>
<button class="mdc-fab app-fab--absolute" aria-label="Edit">
<span class="mdc-fab__icon">
<svg width="24" height="24" viewBox="0 0 24 24">
<path d="M3 17.25V21h3.75L17.81 9.94l-3.75-3.75L3 17.25zM20.71 7.04c.39-.39.39-1.02 0-1.41l-2.34-2.34c-.39-.39-1.02-.39-1.41 0l-1.83 1.83 3.75 3.75 1.83-1.83z"/>
</svg>
</span>
</button>
Note In this example we are using an SVG icon. When you are using SVG icons do not specifiy the fill
attribute. Fill is set by the components where SVGs may be used.
Adding ripples to FABs
To add the ink ripple effect to a FAB, attach a ripple instance to the
FAB element.
mdc.ripple.MDCRipple.attachTo(document.querySelector('.mdc-fab'));
You can also do this declaratively when using the material-components-web package.
<button class="mdc-fab material-icons" aria-label="Favorite" data-mdc-auto-init="MDCRipple">
<span class="mdc-fab__icon">
favorite
</span>
</button>
FABs are fully aware of ripple styles, so no DOM or CSS changes are required to use them.
Classes
Block
The block class is mdc-fab
. This defines the top-level button element.
Element
The button component has a single span
element added as a child of the button due to buttons not adhering to flexbox rules
in all browsers. See this Stackoverflow post for details.
Modifier
The provided modifiers are:
Class | Description |
---|
mdc-fab--mini | Makes the fab smaller (40 x 40 pixels). |
mdc-fab--plain | Makes the FAB have a white background. |
