Likewise, I appreciate the patience whilst I finally got around to talking about what you were actually trying to discuss. I agree that it should ideally always be a person's aim to learn how and why the tools they're using work. That's the only way to become a true master of your medium. And if they don't, there's certainly cases where that tool will become a crutch rather than something used for its advantages. I can see that frameworks definitely have that risk attached to them. I will admit that I didn't try downloading just the Bootstrap grid. I simply looked at the customise screen and made an assumption. So it's good that you checked it out yourself and called me out on it. It's a bit lame to receive a substantial amount of unexpected and unwanted CSS.
