I'm working on a Drupal site/theme. The CSS and PHP modifications are fairly easy; they just take a little time to learn and get working exactly how I want.
However, I'm having issues applying CSS styles to some elements because of what I think is a property function.
The code looks like <h2 property="dc:title" datatype="" class="node-title">.
What is a property function and what does it do or control within the page? Also how can I modify or remove it?
It's not a property function; it's an attribute that is used from RDFa, and that is added from the RDF module.
The easier way to remove those attributes is to disable the module, but I would not suggest doing it, as the purpose of that module is to enrich your content with metadata to let other applications better understand its relationships and attributes.
Alternatively, if the problem is just with that property, used for the nodes, then you can implement code similar to the following one:
function mymodule_preprocess_node(&$variables) {
if (isset($variables['title_attributes_array'])) {
$variables['title_attributes_array']['property'] = NULL;
}
}
The module should be executed after the RDF module, to allow its hook to be executed after the one implemented by the RDF module.
I have not seen any compatibility problem between the attributes added by the RDF module and the JavaScript code executed by Drupal core or third-party modules. It would probably be the case to investigate why you are having problems with the JavaScript code when those HTML attributes are added.
in your css file, put:
h2[property="dc:title"]{color:#FFFFFF;}
or if it is a link, you may need:
h2[property="dc:title"] a {color:#FFFFFF;}
From wikipedia, check out RDFa
RDFa (or Resource Description
Framework – in – attributes) is a W3C
Recommendation that adds a set of
attribute-level extensions to XHTML
for embedding rich metadata within Web
documents.
It is basically a way to add more metadata to XHTML docs for better semantics.

I've made an Add-on which is a custom field.
The style of the text in the field changes depending on the properties of an issue.
I check which style should the text have in the .java file and I pass the html class in a variable called $indicator to the velocity template:
#if( ${value} )
<span class="$indicator">${value}</span>
#end
It works perfect everywhere but in gadgets. When I add this field to a table showing issues in a dashboard, the html code is correct, but it doesn't find the css resource. This is because gadgets are inside an iframe.
How can I make the iframe have a reference to the stylesheet?
You did not say exactly which gadget you were using, but try adding the following context within your <web-resource> module:
<context>jira.webresources:issue-table</context>
The above should work for at least Assigned to Me, Filter Results, In Progress, Voted, and Watched in JIRA 6.1+.
If that does not work, you might also try:
<context>com.atlassian.jira.gadgets:common-lite</context>
If that general context doesn't work, you can look for which exact contexts are #requireContext'ed by the specific gadget you are trying to use, and then make sure that your web-resource is listed in that context. You can figure this out by looking at the gadget's XML and then searching for the #requireContext. (You can find the gadget XMLs inside $JIRA_DATA/plugins/.osgi-plugins/transformed-plugins/jira-gadgets-plugin-*.jar)
Starting with JIRA 7 the Answer of Scott Dudley is no longer working. #requireContext was replaced with a #requireResource within the Atlassian sources of this gadget.
As it affects our plugin, I created a Improvement Request to make that possible again
I'm trying to register a custom content type, similar to this question on MSDN forums: I want to register a custom extension that is essentially an HTML file, e.g.:
[Export]
[DisplayName("My Custom Markup")]
[Name("mycustom")
[BaseDefinition("html")]
internal static ContentTypeDefinition MyCustomContentType;
[Export]
[FileExtension(".mycustom")]
[ContentType("mycustom")]
internal static FileExtensionToContentTypeDefinition MyCustomFileExtensionDefinition;
So by specifying BaseDefinition as html, I am able to get HTML highlighting in .mycustom files, unfortunately I get nothing else, in particular, the HTML intellisense. From the above link it seems that the only way to have Visual Studio recognize custom extensions as a specific editor type, but I'd have to hack the registry (or more specifically, provide this via the ProvideEditorExtension attribute, but it's only applicable on a VSPackage).
So my question is, basically, is there an alternative way to register a custom extension to an editor programmatically, but without creating a custom VSPackage for it? Other than hacking the registry, of course?
(I could be totally wrong with the approach, in which case your help is very much appreciated!)
The easiest way is to use the technique demoed here:
http://blogs.msdn.com/b/noahric/archive/2010/03/01/new-extension-css-is-less.aspx
This is effectively "hacking the registry" but in a supported way. You're simply wrapping the needed keys in a .pkgdef file (essentially a .reg file) that can be contained in an editor extension.
I am a total beginner so pls be patient with me if my question might sound too dumb.
I am studying html, css, basic native php, and cakephp at the same time (which is not a good idea, I think its better to master the native cakephp first before jumping to any framework). As far as I know classes and ids are for css styling until I stumbled upon this code when I am studying cakephp:
<div class="posts index">
.
.
.
</div>
Note: I scaffolded a Post
I tried to look in the default css of cakephp for the class "posts index" but I can't find it so I concluded that there may be other uses of html classes aside from css. I am not sure about. I am just guessing. Can somebody explain to me in general about html classes. I also wanna know about the class "posts index" regarding its significance to cakephp. Pls help...
first of all you have to separate your "business logic" (program logic) and your "view" (output). The logic is done by your php code, it doesn't matter whether you use a framework or not. Your output can be html, xml, wml or some other stuff and is generated by your logic, your php code.
-> The class definition is only relevant in your output, so it doesn't matter for your cakePHP!
Next, there's no syntactic rule that every class in html must be defined in css. So your conclusion uses a rule that does not exist :-) It is not nice code because you have unused and needles html code, but it is not wrong. Most frameworks and tools use such "default classes" because of template support. Look at the html code of wordpress templates, there you will find these classnames, too, to make it more easy to change your css files to get different look&feels. When you create a new template with css styles, you know that the "posts index" element contains post-entries...
You can use classes and ids in JavaScript to get and identify elements, but this belongs also to the output/client-side area.
BTW: if you parse your html with some php code and need the class definition to identify an html element in the DOM then it matters, but I don't think you want do this ^^
We primarily use an ASP.NET environment at work. Right now I'm building an application which uses "Modules", which is just a UserControl, with its' Javascript right in the control, and a link element to the stylesheet for that control. I want to keep it modular, and would like the style of this control to be independent from the markup/javascript.
So I'm wondering what the preferred method of doing this is? Obviously if I didn't want the "theme" functionality I'm after, I could just use style tags at the top of the control. Right now I have a link element, as I said, and this isn't proper I don't think.
Does anyone have any preferred methods, and if so, what and why?
I considered ASP.NET themes briefly, but the idea of these controls are a little different, I think.
It's basically a shopping cart system. I don't want to get into it all, but we are using a really neat security system, and we don't want to use a premade shopping cart. I'm developing a set of controls that can be dropped on a page, for instance in SiteFinity (which is the CMS system we use) or for any other project we might have. Normally I would compile these into a DLL so we get ACTUAL controls we can drag & drop from the toolbox, then I could use internal "generic" styling and allow for any additive styling someone might want, as well as supplying a few fancier styles as well.
This is the first time I've ever done this, or really the first time anyone in our shop has done this either so I'm kind of figuring it out as I go. I might be pretty far off-base, but hopefully I'm not.
Right, the idea for this is to have a "theme", which is really just a CSS file and a jQuery template. I have them named the same, and have a Theme property on the usercontrol to set it.
When these controls are finalized, I might refactor the javascript to a RegisterScriptBlock on the code-behind, but for now they just in script tags on the control itself.
What prompted this question was DebugBar for IE, giving me warnings that link elements are not allowed inside a div. I don't much care, but after thinking about it, I had no idea how to link to the css file without doing that. I considered very briefly having an 'empty' link tag on the master and then setting THAT in the code behind on Page_Load of the UserControl, but that just seems like ass.
I could use #import I guess but I think link tags are preferred, correct?
It sounds like you're rolling your own theme engine... why not use ASP.NET Themes?
If you're determined to do it yourself, here's some code from the CssFriendly project that may be of interest to you. (I think it should be ok to post the code as long as I cite where it's from.) The .css files are flagged as Embedded Resource and the code below is used to include them as needed.
string filePath = page.ClientScript.GetWebResourceUrl(type, css);
// if filePath is not empty, embedded CSS exists -- register it
if (!String.IsNullOrEmpty(filePath))
{
if (!Helpers.HeadContainsLinkHref(page, filePath))
{
HtmlLink link = new HtmlLink();
link.Href = page.ResolveUrl(filePath);
link.Attributes["type"] = "text/css";
link.Attributes["rel"] = "stylesheet";
page.Header.Controls.Add(link);
}
}
I think what you're supposed to do is use Page.RegisterScriptBlock to register your script blocks. Best-case you shouldn't have them inline in your ascx inside script blocks. This isn't always possible, but theoretically it's the best way.
Ideally your styles should be separate from your markup as well. Your controls can have classes and IDs, but your style is based on your application and not your controls. Controls can theoretically be used in other applications where you might want a different style.
It depends on how big your app is, and whether or not it's dependent on Themes elsewhere, IMHO.
If you're using a .skin file, or if the majority of the app is also plugged into the theme, you might as well go with the theme.
But if it's just a few styles you need, you're better off to set the stylesheet manually, keep your css file external (inline styles are a PITA and defeat one of the core purposes of css).
In either case, don't forget to set the CssClass attribute on your controls.
To be proper I would have an import.css file - structure the naming of the classes to follow your controls, and import the styles within the header of the document.
If you have a module called "30DayPricingCalc" then you could name the classes/id's:
30DayPricingCalc.css
.30daypricingcalc_main_content
{
...
}
Also if you haven't I would setup a list of generic reusable styles to save you room. Since elements will allow multiple classes per object.
Also, link tags matter a lot less now than they used to. we're well past support for IE5 generation browsers and IE6 supports the #import tag.
Cheers!
I know that you can apply CSS in order to style objects in Flex using the StyleManager:
http://livedocs.adobe.com/flex/3/html/help.html?content=styles_07.html
You can also load compiled CSS files (SWFs) dynamically:
http://livedocs.adobe.com/flex/3/html/help.html?content=styles_10.html
However, I'm dynamically creating my CSS files using a web GUI and a server-side script.
If the CSS is changed, then the script would also need to compile the CSS into an SWF (which is not a viable option). Is there any way around this?
In this comment to an issue related to this in the Adobe bug tracker T. Busser is describing what might be a viable solution for you:
"I've created a small class that will 'parse' a CSS file read with an
HTTPService object. It takes apart the
string that is returned by the
HTTPService object, break it down into
selectors, and create a new
CSSStyleDeclaration object for each
selector that is found. Once all the
properties are assigned to the
CSSStyleDeclaration object it's added
to the StyleManager. It doesn't
perform any checks, you should make
sure the CSS file is well formed, but
it will be sufficient 99% of the time.
Stuff like #font, Embed() and
ClassReference() will hardly be used
by my customers. They do need the
ability to change colors and stuff
like that so they can easily theme the
Flex application to their house
style."
You could either try to contact this person for their solution or alternatively maybe use the code from this as3csslib project as a basis for writing something like what they're describing.
You can also implement dynamic stylesheet in flex like this . Here i found this article :
http://askmeflash.com/article_m.php?p=article&id=6
Edit: This solution does not work. All selectors that are taken out of the parser are converted to lowercase. This may work for your application but it will probably not...
I am leaving this answer here because it may help some people looking for a solution and warn others of the limitations of this method.
See my question: "Looking for CSS parser written in AS3" for a complete discussion but I found a CSS parser hidden inside the standard libraries. Here is how you can use it:
public function extractFromStyleSheet(css:String):void {
// Create a StyleSheet Object
var styleSheet:StyleSheet = new StyleSheet();
styleSheet.parseCSS(css);
// Iterate through the selector objects
var selectorNames:Array = styleSheet.styleNames;
for(var i:int=0; i<selectorNames.length; i++){
// Do something with each selector
trace("Selector: "+selelectorNames[i];
var properties:Object = styleSheet.getStyle(selectorNames[i]);
for (var property:String in properties){
// Do something with each property in the selector
trace("\t"+property+" -> "+properties[property]+"\n");
}
}
}
You can then apply the styles using:
cssStyle = new CSSStyleDeclaration();
cssStyle.setStyle("color", "<valid color>);
FlexGlobals.topLevelApplication.styleManager.setStyleDeclaration("Button", cssStyle, true);
The application of CSS in Flex is handled on the server side at compilation and not on the client side at run time.
I would see two options then for you (I'm not sure how practical either are):
Use a server side script to compile your CSS as a SWF then load them dynamically.
Parse a CSS Style sheet and use the setStyle functions in flex to apply the styles. An similar example to this approach is the Flex Style Explorer where you can check out the source.
Good luck.
