Value Details
block Full-width button with rounded corners.
full Full-width button with square corners and no border on the left or right.

Fill

This attributes determines the background and border color of the button. By default, buttons have a solid background unless the button is inside of a toolbar, in which case it has a transparent background.

Value Details
clear Button with a transparent background that resembles a flat button.
outline Button with a transparent background and a visible border.
solid Button with a filled background. Useful for buttons in a toolbar.

Size

This attribute specifies the size of the button. Setting this attribute will change the height and padding of a button.
