is it anything to do with css. Else how can we use css tags in jquery?

Answer 1

this is .css()
I recommend to you jQuery Docs to start
You can come back with more specific question...

Answer 2

It looks like gallerrax is a custom jQuery plugin, and I believe that only the author of it can tell you what it does. In that peace of code you are calling gallerrax for all HTML elements that have ID attribute equal to gallery.

There is no CSS tags, because CSS is not a HTML element. You can deal with CSS using jQuery like >this<.

Good luck. =)
