Yes, headline is obviously a wink to
Responsive with Skeleton - a proposal to get Responsive Web Design - but a different perspective;
I'm not sure but I believe Jeremy has mentioned intentions to implement some kind of flexbox solution for TW layout. So I just wanted to link to this neat
Flexbox demo site. Among other things it demos the Holy Grail layout which I guess is appropriate for TW. It also demo's a flexbox based grid that appears very simple.
While I'm not sure Flexbox would simplify TW-users CSS hacking per se, I do believe it would make general page element "layouting" easier and maybe opening up for abstraction of flexbox commands + "extension-css" into wikitext. Again, I'd think this is a "core matter" rather than a mere "theme matter". I have no practical experience with Flexbox though so welcome any thoughts on the matter.
