Compiler flags
The first thing we're going to play around with is one of the least likely to blow up in your face. Compiler flags are used to define constants at build time, that can then be used in your code to do some tricky things to customize your code for specific build configurations.
There are 3 possible places to set these up:
OTHER CFLAGS (Other C Flags)
GCC PREPROCESSOR DEFINITIONS ( Preprocessor Macros)
INFOPLIST PREPROCESSOR DEFINITIONS ( Info.plist Preprocessor Definitions…

This is all coming from boostrap-responsive.css. Compiling from source actually turned out to be useful right away, because the LESS templates generate a lot of code for each of those layouts. You could remove them from the generated css file, but it would be a lot more code. With the LESS templates, you can comment out the wide layout in one line, and modify another and have it stop expanding beyond 768px wide:
