Using POST with multiple buttons on a form with CppCMS

Question

I am following this CppCMS tutorial along with its sample code. There is a single button in the form, and the template contains something like this:

<form method="post" action="" > 

1. How can you use POST with multiple buttons on a form to do different things?
2. How can you design the layout, sizing, coloring, background color for different buttons with CppCMS?
