My short talk how CSS Flexbox will help creating "flexible" Web Apps. It was recorded at this years Fronteers Jam Session.
Quick note: @kizmarh actually did the header example with floats alone by reordering the DOM elements (nice trick). But I think it’s still a bit limited and only one “flexible” element is possible. Also, Flexbox has lots of other cool features I haven’t mentioned.. like reordering and wrapping.
PS. This was my first time ever talking in front of people.. so it might be a bit rough and rushed. ;-)
Update: Uploaded the Mail UI example, but the code might be a bit messy. I just quickly did for the talk. Also, only tested in Chrome.
