JQuery .animate question

On w3schools.com, they say the "params" defines the CSS properties to be animated.

$(selector).animate({params},speed,callback);

But I see we can also insert other functions { scrollTop: 0 } into the same area, which isn't CSS.

function $nameHere () { $('body,html').animate({ scrollTop: 0 }, 800); }

Could someone just explain why, and what other functions can be used here also.

Thanks :D

On the official documentation it says "In addition to style properties, some non-style properties such as scrollTop and scrollLeft, as well as custom properties, can be animated."

Fantastic! I will have a play with scrollLeft also.

Thank you.
