Callout styling
For the handbook, particularly for the sales demo, I often need to add "comments" or "callouts" that add content out of the main flow. I envision something off the margin to the right, like comments in Google Docs. Can we get some a CSS class I could apply to these callouts?
For examples, take a look at https://about.gitlab.com/handbook/sales/demo/ and look at all the TODOs. They get in the way of the main content, but we don't want to lose them.
