This style is for Google Calendar after the re-design that was implemented on or about May 18, 2010.

Sizing the content window for the calendar grid--or vice versa--ain't workin' so well since the May2010 re-design of Calendar. There's an annoying scroll bar now on the right which serves no real purpose except to eat up some precious pixels better used for actual content. For Firefox, hiding the bar eliminates the several pixel's worth of scrolling caused by the re-design, but it also removes the ability to scroll the settings pages/tabs (so being able to turn this style off and on as needed is kind of essential--no problem with Stylish). For Chrome, hiding the bar doesn't eliminate the ability to scroll pages/tabs--so no problem with settings (and no need to enable and disable the style), but it doesn't eliminate the scroll for the main calendar page either; still, it does remove the unneeded bar, so that's something.

17Jun2010:
OK... a little bookmarklet goodness--in Firefox, even with the scroll bar hidden and the mouse wheel not functioning, you can use javascript to "scroll" up and down (in Calendar Settings, for instance):

Up-> javascript:window.scrollByPages(-1);
Down-> javascript:window.scrollByPages(1);
Top-> javascript:window.scrollTo(0,0);
====> For these next 2, 114px is about the distance one 'tick' of a mouse wheel will take you:
Down a little-> javascript:window.scrollBy(0,114);
Up a little-> javascript:window.scrollBy(0,-114);

(stick 'em in some bookmarks and voilà: no scroll bar, no problem)
