This is the challenge of writing entire CSS layout system with one line CSS class. I just wanted to prove how easy CSS can be, and with little imagination we can be build cool things. I started with the principle that every column can be divided by two, becoming half column or 50% column. So how can we build CSS Layout system with this principle? One column can become 2 (50%) column or 100% = 50% + 50%. So we can make 2,4,8,16, … layout system. Believe it or not we only need this line of CSS code:
This is better than all three prequels added together, then squared, then multiplied times six fuckillion and three.
