There is no comment functionality for CSS. If you like to work on it here are the comments. There's only one comment for CSS.
/* one line */ body { /* background-color: red; */ color: gray; } /* multiple lines */ /* body { background-color: red; color: gray; } */ I personally use a trick /* deactivated block */ /** body { background-color: red; color: gray; } /**/ /* activated block */ /**/ body { background-color: red; color: gray; } /**/ The difference is only the missing one slash within the line above "body". -- <https://forum.pspad.com/read.php?4,77206,77209> PSPad freeware editor https://www.pspad.com
