Build Page in Lightning missing "Page Include" under advanced.

I cannot get my pages to be responsive.  The process to make them responsive seems to be more of an art than a science as they do not respond on iphones or ipads.  I am sure it is user error but cannot find any tutorial for when to use which feature and I end up with lots of extra space on the right on small devices.  Thee responsiveness works fine when resizing my desk top.  Thought lightning might be a solution. Thanks Rob.
