Custom section in Markdown

Hi, I am a Rust and Zola beginner. Sorry i someone already asked this question. Is there a way to put custom markdown section? I want to create a special block for putting a “Series Info”, or “Tips” or “Notes” in my blog. This block will have a background color of green for example, but I still want to be able to use markdown format for writing inside that block.

Something like this:

You can probably make that work as a shortcode and using the | markdown filter on the body in the template.
