Jason Hoffman of CSS Tricks took a trip down memory lane this week. His article A Look Back at the History of CSS gives an account of how we came to style websites in the first place. From Marc Andreessen claiming there was no way to style a website with HTML back in 1994 to SCSS in 2017, the language has come a long way. You get to see how CSS code used to look (things were measured in centimetres at one point) and how browsers found it difficult to translate it all.
