/**
 * TStyleSheet class.
 *
 * TStyleSheet represents the link to a stylesheet file and/or a piece of
 * stylesheet code. To specify the link to a CSS file, set {@link setStyleSheetUrl StyleSheetUrl}.
 * The child rendering result of TStyleSheet is treated as CSS code and
 * is rendered within an appropriate style HTML element.
 * Therefore, if the child content is not empty, you should place the TStyleSheet
 * control in the head section of your page to conform to the HTML standard.
 * If only CSS file URL is specified, you may place the control anywhere on your page
 * and the style element will be rendered in the right position.
