Problem with ASP.NET calendar component

[schizo]

I'm attmepting to style the background color of the "SelectedDayStyle" attribute of the calendar component with CSS. But no matter what I do, the background color always appears as gray. My code snippets are shown below:

ASP:

<asp:Calendar ID="myCalendar" OnSelectionChanged="displayDates" OnLoad="displayDates" Runat="server" CssClass="calendar" NextMonthText=">>" PrevMonthText="<<">
    <TodayDayStyle CssClass="today" />
    <DayStyle CssClass="day" />
    <OtherMonthDayStyle CssClass="otherMonth_day" />
    <TitleStyle CssClass="title" />
    <NextPrevStyle CssClass="changeMonth" ForeColor="white" />
    <SelectedDayStyle CssClass="selectedDay" />
</asp:Calendar>

CSS:

.selectedDay
{
	background-color: #000000;
	background: #000000;
}

All my other elements are styled just fine in CSS. Has anyone else tried setting the background color of the SelectedDayStyle via an external CSS file?

Upon further research, I have concluded that the calendar compnent is not fully CSS customizable as mentioned here. Even though you can set a CssClass property of each paramater in the calendar object, some default styles will overright your class.

In short, I would not recommend this component... thanks Microsoft.
