    The this.Page.Header.Stylesheet.CreateStyleRule method lets you add styles to the <head>. However, the CSS attributes that you can specify are limited to those supported by the Style class. (You can derive your own class from Style if you need additional attributes.)

    C# example:

    protected override void OnPreRender(EventArgs e)
{
    base.OnPreRender(e);

    // Create a Style object for the body of the page.
    Style bodyStyle = new Style();

    bodyStyle.ForeColor = System.Drawing.Color.Blue;
    bodyStyle.BackColor = System.Drawing.Color.LightGray;

    // Add the style rule named bodyStyle to the header 
    // of the current page. The rule is for the body HTML element.
    this.Page.Header.StyleSheet.CreateStyleRule(bodyStyle, null, "body");
}
