Cross browser support jQuery

jQuery is famous for cross browser compatibility but, which all properties or functions don't have a cross browser support?

I know one: ui-corner-all class won't produce rounded corner effect in any IE 开发者_C百科browsers.

This isn't a jQuery Core feature, but a jQuery UI one. When it comes to jQuery UI the functionality will work, but older browsers may not get all the bells and whistles with the styling.
