I really like CSS Zen Garden and it had a profound impact of how I think about front-end work. I see a lot of back-end developers trying to force the markup and their styling to conform to what they want.

If you understand how the document flows, separate your CSS from your markup, write clean and valid markup and keep everything as minimal as possible. There is really a "zen" like element to it which I think is kinda lost today.

However when it comes to code I am a minimalist and tend to do as much as possible with Vanilla JS.
