Responsive layout

Hello everyone,

I am quite new to DHTMLX and I have been working on it trying to understand how everything connects together. I have managed to build a working layout but one thing still remains. How can i make an element full width?

Let’s say I have a Ribbon or a Form for example. These elements will have a border around them, making up a box. The thing is that if they do not go full width it totally breaks the layouts harmony because I’ll be left with a box and a bunch of white space with a border right in the middle of it.

So, is there a simple way to make an (any) element full width?

Thank you.
