1. Long name or phrase you can use the middle horizontal line to name the selector.

2. It is not recommended to use the "_" Underline to name the CSS selector, why?

Add a status prefix to the selector

Sometimes you can add a prefix to the selector to indicate the status, so that the semantics are clearer, such as adding the ". is-" prefix.
