How can I use code design pieces?

Like this:

LOL

I don't know

1. Go to https://chrome.google.com/webstore/ on a modern browser (Chrome or Edge works best)
2. Download a CSS Editor (I use https://chrome.google.com/webstore/detail/stylus/clngdbkpkpeebahjckkjfobafhncgmne )
3. Ask @bsrti or @TheCheesePhoenix for the code.

Currently this piece is not available in white and black

If possible, I will use photoshop to make the colors white and black

this is totally REASONABLE
