Comments make your code clear and readable for others. It is important that you are able to understand them clearly. That is why this chapter starts with some notes and examples of comments.
Tip
Don't be sparse with your comments when keeping the file size, download time, and performance in mind. In the process of compiling and minimizing your final CSS code, comments and other layout structures will be effectively removed. You can add comments for understanding and readability wherever needed.
In Less, you can add comments in the same way as you did while writing the CSS code. Comment lines are placed between /* */. Less also allows single-line comments that start with //.
Using Less, only the true CSS comments (/* */) will be included in the generated CSS file. Minimizers will remove these comments in your final compiled style sheet. An example of this can be seen in the following code:
/* comments by Bass
.mixins() { ~"this mixin is commented out"; }
*/
