The "Join Now" button on http://jointhegame.kde.org/ right now is just a plain graphics. The rest of the site is translatable, but not this button. 

The task would be to implement the button with html and  css while trying to keep its overall look. Once finished this can be used to translate the button as well and have a fully translated Join the Game website.

Additionally, once a person has signed up, there is another button labeled "Pay now". It has the same look and can benefit from the same transformation.
