/** |
|
13
|
|
|
* TStyleSheet class. |
|
14
|
|
|
* |
|
15
|
|
|
* TStyleSheet represents the link to a stylesheet file and/or a piece of |
|
16
|
|
|
* stylesheet code. To specify the link to a CSS file, set {@link setStyleSheetUrl |
|
17
|
|
|
* StyleSheetUrl}. |
|
18
|
|
|
* Since Prado 3.3.1, it' possible to import css libraries bundled with |
|
19
|
|
|
* Prado from template via the {@link setPradoStyles PradoStyles} property. |
|
20
|
|
|
* Multiple Prado libraries can be specified using comma delimited string of the |
|
21
|
|
|
* css library to include on the page. For example, |
|
22
|
|
|
* |
|
23
|
|
|
* <code> |
|
24
|
|
|
* <com:TStyleSheet PradoStyles="bootstrap, jquery.ui.progressbar" /> |
|
25
|
|
|
* </code> |
|
26
|
|
|
* |
|
27
|
|
|
* The child rendering result of TStyleSheet is treated as CSS code and |
|
28
|
|
|
* is rendered within an appropriate style HTML element. |
|
29
|
|
|
* Therefore, if the child content is not empty, you should place the TStyleSheet |
|
30
|
|
|
* control in the head section of your page to conform to the HTML standard. |
|
31
|
|
|
* If only CSS file URL is specified, you may place the control anywhere on your page |
|
32
|
|
|
* and the style element will be rendered in the right position. |
