jquery-migrate is most probably not needed, but isn't there a slider-specific JS to exclude? also have a look at the HTML source, there could be slider-specific JS in there you'd want to exclude too.
regarding CSS: in most browsers (will, in FF at least) you can view source your HTML and then in there click on the link to your CSS-file to see that source.
(if you want, you can post your URL here and I can have a look, might be more efficient)
