Awesome stuff.<p>I can't wait for Flexbox wide-spread adoption - especially in popular frameworks. It's too bad so many people are forced to not be able to use it because of IE9's total lack of support [1]. TBH, I'm not even sure if there's a good polyfill for it.<p>Dimitar Stojanov (@justd100) wrote a super kick-ass write-up on scotch.io covering basically everything there is on Flexbox [2]. It's probably much quicker than 20 videos, has an amazing interactive demo, been shared over 2.4k times, and is probably the best write-up on Flexbox I've read (I'm obviously biased though).<p>[1] <a href="http://caniuse.com/#feat=flexbox" rel="nofollow">http://caniuse.com/#feat=flexbox</a><p>[2] <a href="https://scotch.io/tutorials/a-visual-guide-to-css3-flexbox-properties" rel="nofollow">https://scotch.io/tutorials/a-visual-guide-to-css3-flexbox-p...</a>
