Typo in:

domino-ui-demo/buttons/src/main/java/org/dominokit/domino/buttons/client/views/ui/ButtonsViewImpl.java

Line 852 in 400ae14

element.appendChild(Card.create("METARIAL DESIGN BUTTONS", "Use any of the available button classes to quickly create a styled button")

It says "METARIAL", but "MATERIAL" is meant instead.
