Not sure I completely understand what you are asking. Can you provide some more detail or an example?
You can disable CSS by removing it or 'commenting it out' like so:
Single-line comment:
/* color: red; */
Multi-line comment:
/* .header {
 color: red;
} */
This will tell the browser to ignore the code inside the comment tags /* */. A shortcut for this in a lot of text editors is to highlight the code you want to disable and press ctrl + /
If you want to stop a stylesheet from being loaded in a html file the comment looks a little different:
<!--  <link rel="stylesheet" type="text/css" href="dontloadthis.css">  -->
Hope that helps, let me know if it doesn't answer your question :)
