With the size and complexity of many websites today, stylesheets can become quite lengthy and cumbersome.

Function and Usage of the HTML Comment

Those media queries alone can add a significant number of new styles to a CSS document, making it even harder to work with. Managing this complexity is where CSS comments can become an invaluable help to website designers and developers. Adding comments to a website's CSS files organizes sections of that code for a human reader who reviews the document. It also ensures consistency when one web professional picks up where another leaves off, or when teams of people work on a site. Well-formatted comments communicate important aspects of the stylesheet to members of a team who may not be familiar with the code.

These comments are also helpful for people who have worked on the site before but haven't recently; web designers typically work on many sites, and remembering design strategies from one to the next is difficult. CSS comments are not displayed when the page renders in web browsers. Those comments are informational only, just as HTML comments are although the syntax is different.

Add the opening comment tag before the code you'd like to comment out disable ; place the closing tag where you want the disabled portion to end. Nothing between those tags will affect the visual display of a site, helping you to debug the CSS to see where a problem is happening. You can then go in and fix just that glitch and then remove the comments from the code. Many coders include comment blocks at the top of any new file with code.
