I am trying have a side column on the left with fixed width, and then, on the right a normal Bootstrap container-fluid.
Even if the sidebar is not inside the Bootstrap structure, it is OK. I mean it hasn't to be with col-xx-xx class.
Whatever I do the main problem is that I don't manage to make the fluid container stays beside the sidebar.
The point is also that if I display to none the sidebar, the fluid container has to use the full width of the page.
