Can anyone explain how/why to use jQuery's CSS hooks?

I have been looking into jQuery's css hooks, and some that are available on Github. I have been able to use them to set some styles with jQuery, but as far I understand it, it only gives me an overly complex way to set a css style. I am obviously missing the point... What can I do with them? Can I make Opera support css columns for example? if so, how? Thanks for your help!

$(".s开发者_如何学编程ub").css({
            'columnWidth':'120px',
            'columnRuleStyle':'dotted',
            'columnRuleWidth':'1px',
            'columnRuleColor':'#ccc',
            'columnGap':'10px'
            });

By adding support for these new or browser specific CSS properties it yes allows you to set then with the $.fn.css() function but it also adds the ability to animate them, which is the main uses for the hooks.

csshooks is good way to implement the new css3 styles across browsers. You can create a csshook plugin for the border-radius which does feature detection and implemented border-radius differently on browsers that support it. Explains it all right here:

From the sound of things, these CSS hooks are useful for supporting browser specific CSS properties that the core .css() function does not.
