DRYing up CSS
Albert Einstein once said, "Out of clutter, find simplicity."
For the longest time, I did not understand what he was trying to convey, but then I started interpreting it by testing its applicability in aspects of my life. My interpretation has since been ‘de-duplicate and reuse.’ I have since been able to go lean to a good extent on many things I do. Be it all the stuff I have in my basement, in my closet, or my code.
