Hey Justin,

Thanks for this awesome write up. Have been playing around with this for sometime now, and must say the fact that anyone can build reusable blocks, this feature is also praiseworthy. For someone new to CSS, I would say it might be a bit tricky at the initial. But, nonetheless the whole flexibility of building a block to be reused for later is a fascination in itself. Though I believe there are other block plugins too who can do this, right?
