Hello @jasonsaayman, here's another PR raised for this issue. it has been a long standing one, so I opted to fix. Would be glad if you could take a look at it. Thank you!

@jasonsaayman Isn't it important to have primary and secondary button styles here? The emphasis on the "Get Started" button looks quite logical.
