Hi Nico,
Basically I’ve designed a bunch of blocks (templates) that my team can use to create pages, and they can just change the text/images to what works for their situations.
This feature: 
Now when they insert that block into a page they’re working on, They don’t have the media queries and what not in the custom CSS that I wrote for that block.
For example:

Now is there a way I can bundle that CSS with the block? That CSS is lost when I save the block to my library of blocks, so my team members don’t get it when they insert the block into their page. I hope that better explains my problem.
My current idea is to just insert a Raw Content element into the block with the CSS, but that’s a bit dirty.
Let me know if that makes any sense to you guys.
TLDR: I want to bundle my custom CSS with the template blocks I make.
