javafx2: css documentation - javafx-2

Reading blogs and articles on using css in javafx, I see class selectors such as
.table-row-cell:empty {
-fx-background-color: -fx-base;
}
.table-row-cell:empty .table-cell {
-fx-border-width: 0px;
}
being used, and indeed they work in my own code. However I can't find anywhere where these are documented - it seems like the official documentation has no mention of them:
http://docs.oracle.com/javafx/2/api/javafx/scene/doc-files/cssref.html.

Refer to this official tutorial Skinning JavaFX Applications with CSS section Default Style Sheet.
The default style sheet for JavaFX applications is caspian.css, which
is found in the JavaFX runtime JAR file, jfxrt.jar. This style sheet
defines styles for the root node and the UI controls. ...
You can find out those selectors in mentioned CSS file.

Use Liferay theme css in Portlets

I would like to define all our styles in a the custom Liferay theme we developed. I want to know if it is possible to use css classes defined in the theme in portlets project. We need to avoid duplicate css files in every portlet project. The aim is that the theme controls all look and feel aspects of our portlets and so if we change the theme (or deploy portlets in another portal container) portlet styles change.
You think this is possible ?
Thanks in advance ..
What you want to do is the recommended way to style both the theme and the Portlets.
Portlet styles should only be affect the layout within the Portlet it belongs. All other styles; colors, fonts, etc., should be defined in the theme's custom.css.
I would advise you to try styling the existing Portlet classes before introducing new ones. Then, if you're really stuck, edit portlet.vm.
Take a look at Liferay's Political Theme:
custom.css
...
.portlet {
margin-bottom: 10px;
.portlet-topper {
padding: 0;
.portlet-title {

Conflicts between Custom theme CSS and Liferay CSS

I am trying to customize the Liferay UI by using custom theme using base as as "_Styled" theme.
I have my own css files which I coped to _diff/css folder of theme and imported them "custom.css" file .However its breaking the presentation of liferay.In my custom CSS I have styles defined for all the standard tags like body,div etc which is impacting the liferay UI too.
How can I resolve this conflict? Thanks in advance!
Quick (and not the best) solution is to remove contents of liferays css file (for example "base.css") and save this empty file in /diff/css/ folder of your theme. This way the base.css will get overriden with your new empty file and thus no styles will get loaded. And your custom.css will be the only stylesheet that is taken into account.
Well, of course it all has an effect on the rest of Liferay as well. Liferay provides quite a bit of the HTML DOM of your page, and if you change the presentation of all of those elements, you'll have to take care to style Liferay's elements too.
Is this a conflict? No. Let's go for the simplest case: You declare div {color:green;}. Of course, now everything, your components as well as Liferay's components, use green text. If you only want to style your own portlets, you might want to specify some portlets: div.portlet-my-own-application {color:green;}
I know that color is a too simple usecase, but I hope it illustrates the solution strategy.
Rather than following Artem Khojoyan's suggestion to override Liferay's base.css, I'd recommend to take a look at the resulting css, what's effective etc., and simplify your own css - adapt it to be used within Liferay - by inspecting the effective CSS for every elements that looks off. Firebug or any of it's relatives are your friend.
I'm afraid, with the details "I'm doing something which has an effect on Liferay UI" there's nothing much more to help you. In fact, I'd hope that what you do has an effect on Liferay's UI... You'll just need to find the proper CSS code
Ideally if your styles are loaded from custom.css, then will overwrite liferay default styles.
In some cases, to overwrite a style in css, you can use !important
for example, liferay default style
body {
background-color: #fff
}
You can specify your style to consider irrespective of order of loading
body {
background-color: red !important;
}

Adding CSS class or style to p:message

I have single p:message for which I want to set display: inline-block.
I've tried the following:
<p:message ... styleClass="inline-block" style="display:inline-block;/>
But when I see the sources, both style and class are NOT rendered on the div with messages.
Is there any way to specify the custom CSS attributes to the p:message directly?
I'm aware I can wrap it with div and steer the CSS of the children of that div, but I'd like to avoid superfluous wrapping, if possible.
PrimeFaces version: 3.5.
Have to disagree with Hatem Alimam
As the mykong article goes, you should add your stylesheet to override the Primefaces CSS.
!important in CSS stylesheet is seen as bad practice. Check these quick SO answers to see what the SO community thinks:
Is !important bad for performance?
What are the implications of using “!important” in CSS?
Is it bad to use !important in css property
The last one has an answer in defense of the !important but brings about the problem when several !important rules come into play (and if you start using it without reserve, you are bound to have it blow in your face and they start cascading one after the other.
The right way to do it is either to make your stylesheet have precedence over the PF sheet, to make your selectors get precedence over the ones in PF in the cascading.
Google for CSS selector Specificity for more on how to make sure your rule is picked by the browser over the PF ones (I am at work now and can't access blogs).
Onto your specific question:
The attributes do not work because they are not coded in the component. Check the PF user guide for your particular PF version (at the time of this writing, you have not stated your version). The <p:messages> component has a rather peculiar way of rendering.
for your particular case, add the following rule:
.ui-messages.ui-widget {
display: inline-block;
}

How change the menubutton icon in primefaces?

I would like to put a custom icon in a p:menuButton, is this possible?
Yest it is possible. All you need to do is to override primefaces css classes generated for the p:menuButton.
Approach:
In the rendered web page you can right click on the generated p:menuButton and -> inspect element. There you can inspect all of the related css classes.
You can try to experiment with them (which I would advice, if you have time) for better understanding of css selectors and so on ...
The .ui-menubutton .ui-state-default .ui-icon are the classes that you need.
So now when you know which css classes are related to the icon you can override them :
Add .ui-menubutton .ui-state-default .ui-icon rule to your stylesheet (I assume you have one and it is sucesfully imported and working. If not check here.)
yourStyles.css :
.ui-menubutton .ui-state-default .ui-icon {
background: orange; /** insert your background image **/
}
This will override icons of all p:menuButtons used in your project. If you want to reduce it to some particular p:menuButton then add its ID to the style definition.
#menubID.ui-menubutton .ui-state-default .ui-icon {
background: orange; /** insert your background image **/
}

How to add icons to Dojo grid header?

How can i add icon to dojo grid header. I tried setting the headerClasses with appropriate css class but dint work.
sample css class i used
.sample{
background : url ('______') no-repeat right top;
}
this never worked for me.
Any help would be great.
basically you needed to add ".tundra" in front of .sample because the .tundra stylesheet is at the top of the hierarchy.
