title: Clarification of W3 css standard media query - "only"
body: <p>I want to use the media property to link to different css files based on the user agent.  I am confused by how the keyword "only" is used.   The W3 site states that "The optional “only” keyword can be used to hide the stylesheet from older browsers. The browsers process media queries starting with “only” as if the “only” keyword is not present."  Isn't this a non-statement?  I read it as saying "If the keyword 'only' is present, older browsers ignore it."  Then why use it?  I know I'm missing some vital info here.  Can anyone help?</p>
