I'm in an MVC 4 project, using bootstrap, and I want to know if I have to tweak the configuration so that the button that expands the menu appears on some larger screens.
Thus: link
There is some distance where that menu button appears, it is this distance that I need to change.
This value is defined by one or more lines similar to this in css:
@media ... max-width: 1200px
The min-width and max-width determine what page size will receive that CSS, adjusting it according to your need you change the points where the layout change occurs.
If you want a particular element appearing independent of the screen size, then move the desired CSS stretch out of the @media { ... }.
