5. Making it look pretty

First and foremost, don't get too caught up in making it look pretty before you have the functionality nailed down. Colors, images and fonts all contribute to making the site look amazing but focus on the architecture and core functionality first as this is the foundation of your web application.

Furthermore, LANSA gives you a decent starting point by providing a set of System Themes. You can always come back to this later and create your own User Defined Theme.
