jQuery UI: DatePicker ONLY CSS?

Question

I'm using both the jQuery UI accordion and the datepicker.

The accordion works great, but when I add the CSS file to the page (which is needed by the datepicker), everything goes nuts. I see that the script adds all kinds of classes to both widgets. Is there any way to get a separate CSS that only works for the datepicker? I tried downloading different files from their site, but nothing worked. Any suggestions?

Answer 2

Yes you can. Using the jquery UI themeroller scope.

In the right hand column of the download section (under the theme drop-down menu) There is a link to open the advanced menu. The value you input for the scope can be a custom class - such as .ui-stylized or whatever you class you want the css to apply to. You can even mix and match entire themes if you'd like.

I would recommend using the themeroller to modify any jquery ui specific CSS.

Cheers!
