CSS Comments

A comment is a note in your CSS code. The browser ignores it. Comments help you to explain your code and to remember why you wrote something.

Syntax

A CSS comment starts with /* and ends with */.

/* This is a single-line comment */
h1 {
  color: blue;   /* a comment after a declaration */
}

/*
  This is a
  multi-line comment
*/

Comment out code

Put a comment around a rule to switch it off for some time, without deleting it.

p {
  color: red;
  /* background-color: yellow; */
}
Note: CSS has no // style comment. Only /* */ works. In most editors the shortcut is Ctrl + /.

Summary

  • Write comments between /* and */.
  • They can be on one or many lines.
  • Use them for notes and for switching off code.
  • Next: CSS Selectors.
