<div style="background-color: #e6f9e6; padding: 16px 32px; outline: 2px solid; border-radius: 10px;">
Note that this is mainly a tool for helping with tricky markdown, but it's a great idea to use the <a href="https://huggingface.co/new-blog">community blog editor</a> for actual visualization.

Happy blogging!
