As any standard CSS file is also a valid Sas(.scss) file, it stands to reason we can comment as we would in standard CSS:

/* Here is a normal CSS comment */

Remember, using this format alongside the compressed output option will mean that the comment is removed from the resultant CSS. However, if not using the compressed option, the comment will be retained in the CSS.

Sass also allows the use of a double forward slash to define the beginning of a single line comment. This is the same manner in which JavaScript files can be commented; anything written after the double forward slash on the same line becomes a comment. Here's an example from the variable file we just made:

$color9: #FF00FF; // Magenta

Here the comment has been added after a variable has been defined. However it could also be used at the beginning of a line. For example:

// Here is a Sass only comment
