How to build a website which "snaps" to separate content sections...?

I have to agree wholeheartedly.

I agree too. That Blocs web site is a demonstration of what just the core $99 Blocs can do, without requiring any additional addons such as Foundation, Stacks, stacks, Screens, etc. As such it is bloody impressive considering the time taken to build it. It isn’t perfect and was never meant to be I believe, and is a teaching Template for Blocs. To really appreciate this you should look at the type of site that the core RW can build without addons.

These Blocs demos are like cat nip to RW users who have $100’s, if not $1000’s invested in RW who are struggling to build something similar.
