/**
|
|
|
14 |
* TStyleSheet class.
|
|
|
15 |
*
|
|
|
16 |
* TStyleSheet represents the link to a stylesheet file and/or a piece of
|
|
|
17 |
* stylesheet code. To specify the link to a CSS file, set {@link setStyleSheetUrl StyleSheetUrl}.
|
|
|
18 |
* The child rendering result of TStyleSheet is treated as CSS code and
|
|
|
19 |
* is rendered within an appropriate style HTML element.
|
|
|
20 |
* Therefore, if the child content is not empty, you should place the TStyleSheet
|
|
|
21 |
* control in the head section of your page to conform to the HTML standard.
|
|
|
22 |
* If only CSS file URL is specified, you may place the control anywhere on your page
|
|
|
23 |
* and the style element will be rendered in the right position.
