// TODO
// button should have classes:
// button, button-primary, button-secondary, etc.
// button holds all styling with default primary color(will this affect outline/clear?) and
// the other classes change the color
//
// button-clear should have classes:
// button-clear, button-clear-primary, button-clear-secondary, etc.
// button-clear holds all clear styling with default primary color and
// the other classes change the color
//
// button-outline should have classes:
// button-outline, button-outline-primary, button-outline-secondary, etc.
// button-outline holds all outline styling with default primary color and
// the other classes change the color
//
// button-block should stand alone
// button-full should stand alone
// button-round should stand alone
// button-disabled should stand alone(?)
// button-sizes should stand alone (button-small, button-large, etc)
// button-fab errrrr
