If you give an html template a .cfm extension, it'll be processed by ColdFusion. When ColdFusion processes the file, it'll recognize where it needs to output data and will populate the template. It will also look for <cf> tags and perform any additional functionality. ColdFusion has nothing to do with CSS. CSS is a file that the browser is told where to look for. The browser uses the css to style html elements that's presented to the browser, post ColdFusion processing.
Granted, this is a very generic description. There's more to ColdFusion than the basic processing it applies to templates.
