Floating action buttons (FAB)

FAB represents the most important action on a screen. It puts key actions within reach.

Extended FABs help people take primary actions. They're wider than FABs to accommodate a text label and larger target area.

Usage

Link to “Usage”

FABs should have an icon, such as a font md-icon, an svg, or an img.

edit

<md-fab aria-label="Edit">
  <md-icon slot="icon">edit</md-icon>
</md-fab>

Lowered

Link to “Lowered”

FABs can be set to a lower elevation with the lowered attribute.

edit

<md-fab lowered aria-label="Edit">
  <md-icon slot="icon">edit</md-icon>
</md-fab>

Accessibility

Link to “Accessibility”

Icon-only FABs must include an aria-label that describes its action. Otherwise if aria-label is not provided, the FAB will default to announcing its visible contents.

<md-fab aria-label="Edit">
  <md-icon slot="icon">edit</md-icon>
</md-fab>

Extended FABs use their label for accessibility. Add an aria-label for additional context if needed. By supplying the label attribute, the extended FAB will make sure that the icon is not announced.

<md-fab label="Edit" aria-label="Edit Comment">
  <md-icon slot="icon">edit</md-icon>
</md-fab>
