I resent has to do an exercise to show off my HTML page building skill, I had to build a three column site that used the newest layout css3 features. And what is more latest then flexbox? I after using it I had fell in love with it! It allows for quick and proportional layout that would before force me before to use position absolute and awkward percentages. This is exceptionally helpful when I am doing responsive as it cuts my time down in half if I didn't use flexbox.
