TIL: In
@CodePen
posts, you can write custom CSS (or SCSS, or LESS, or whatever) to customize the appearance of your pens — just like in your CodePen profile. 
Here's the SCSS I used to style my post — it's not especially clean but it does go from top-down, and I tried to only use enough specificity to override. I might expand this with some helpful ".info" or ".warning" classes for blocks within the post.

Also I'll try to adjust this so it's a little more customizable and reusable!
