* TStyleSheet class.

* TStyleSheet represents the link to a stylesheet file and/or a piece of

* 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.
