iOS only CSS file?

Is there a way to include a CSS file that only works for iOS? Thanks.

It would be preferred if this is done browser side, although server s开发者_StackOverflowide detection could be a viable option if it works well enough (server is python flask based)

You can use CSS media queries:

You could use some javascript

if((navigator.userAgent.match(/iPhone/i))     //Lines split for easy reading only
    || (navigator.userAgent.match(/iPod/i)) 
    || (navigator.userAgent.match(/iPad/i))){
   //LINK TO YOUR STYLESHEET
}
