SASS supports two types of comments:
Inline comments - These only span one line and are usually used to describe a variable or block. The syntax is as follows: // Your comment here (you prepend it with a double slash (//) and the rest of the line is ignored by the parser.
Multiline comments - These span multiple lines and are usually used to display a copyright or license at the top of a document. You can open a multiline comment block with /* and you can close a multiline comment block with */. Here's an example:
/*
This is a comment
It's a multiline comment
Also a hiaku
*/
