I have images in my theme (in the Content/ directory) and I want to show them in different places.
My current approach is : <img src="#Url.Content("~/Themes/MyTheme/Content/Images/image.gif")" />
This works, but is not very maintainable (what if I want to switch themes, etc).
Is there an built in method, something like GetCurrentThemeDirectory() that would return the directory so I could do or something like that?
Edit: from mdm's comment, I realize that changing the theme isn't a valid concern. I really just want to avoid typing out the url for every reference
Where are you referencing the image from? Module? Another theme?
If it is from the theme that has the image, then you don't need to worry about switching themes. If it is from another theme, then the image should be a part of the theme. If it is from a module, then it would make sense to store the image as part of the module or override it in the theme (see below).
If you wanted to have the image as part of the theme, then you could have the module return a 'default' shape and then override that in the theme. There really shouldn't be any reason to reference the theme's images from a module or vice versa.
Edit after your edit
In the themes I've written, I've followed what the Orchard authors do. Rather than using <img> tags, images are placed in Styles/images. They can then be referenced using the CSS background-image attribute.
In Views/Branding.cshtml:
<div id="header"></div>
<h1 id="branding">#WorkContext.CurrentSite.SiteName</h1>
And then in site.css:
#header {
/* snip */
background-image: url(images/header.png);
/* snip */
}
Themes/TheAdmin/site.css contains plenty more examples of this method.

I am using AEM 6.2 and trying to create a parsys component in crx, using the code below
However, the height of this parsys, in edit mode, comes as 0px.
Attached are the screenshots.
When I manually change the height to some values eg. 40px, it looks fine.
Note: I am not using any client library for the above page. (no css and js)
Futher, All sample sites like geomatrix etc have parsys showing correctly.
Could anyone guide me with what I am doing wrong?
I think that the problem is outside the component or any of the code shown here.
I think what's happening is that the css style for the div that gives the droptarget placeholder its dimensions is not loading.
That's loaded as part of the AEM authoring client libraries which you should be inheriting from the foundation page component.
Examine your page component's sling:resourceSuperType property. It should point to either wcm/foundation/components/page or wcm/foundation/components/page or inherit from a component that does.
If that is set then you have may have blocked one of the scripts within it, quite possibly head.html.
Include following code in the head section of the page component's rendering script.
<!--/* Include Adobe Dynamic Tag Management libraries for the header
<sly data-sly-include="/libs/cq/cloudserviceconfigs/components/servicelibs/servicelibs.jsp" data-sly-unwrap/>
*/-->
<!--/* Initializes the Experience Manager authoring UI */-->
<sly data-sly-include="/libs/wcm/core/components/init/init.jsp" data-sly-unwrap/>
For resolving your issue, you need to include init.jsp in the first before writing down the parsys code. I mean write like this.
<head>
<sly data-sly-include='/libs/wcm/core/components/init/init.jsp' />
</head>
<body>
<sly data-sly-resource="${'par' #resourceType='foundation/components/parsys'}" />
</body>
I think #l-klement pointed it out correctly that the problem is outside component. When I rename the landingpage.html file to body.html it starts working fine. I think this may be because of different files like head.html etc present at wcm/foundation/components/page which is required to provide proper styling and load certain required client libraries which assigns proper styling to parsys.
If the above is true, my next question would be, How can I have my own head.html, body.html, header.html, footer.html etc files without compromising with the parsys styling?
I need to make a footer in Liferay and use theme for it. What's the simpliest way to do it?
I have created new theme, filled _diffs folder with other folders, but it's empty and I couldn't find relevant docs about this. Should I copy all basic files there? What should I change to create footer?
In Liferay, theme's portal_normal.vm serves as the template to
construct HTML structure of the page. There you define your header,
body and footer includes.
When you will look at the portal_normal.vm of classic theme, you will observe following HTML snippet:
<footer id="footer" role="contentinfo">
<p class="powered-by">
#language ("powered-by")
Liferay
</p>
</footer>
This is the footer of the page. This is what you need to implement. However, it's not necessary to use footer tag at all, as you can simply use div or table based structure with bootstrap or customized CSS classes for your footer, it's upto your requirement.
Remember! Classic theme is just like a sample provided by Liferay, so, it's not good idea to directly customize it.
Everybody needs a whole customized view of the site, and for this the best idea is to create a custom theme (that's what you are doing!), that will give you full control over your look-n-feel.
To kick-start, you can initially copy required folders from classic theme to your customized theme's (_diffs folder) and start changing bit by bit.
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;
}
I need do something like that:
I have theme "panel" in /themes/panel and there layout /themes/panel/views/layouts/main.php with example content
<a>$content</a>
I have module "admin" in /protected/modules/admin and there layout /protected/modules/admin/view/layouts/main.php with example content
<b>$content</b>
And on the end i want
<a><b>view</b></a>
Also in /themes/panel/views/layouts/main.php i need load css file from module.
In other explanation:
I have one template for all panels (header, css files, footer), but each of panels need separate layout (only the middle of content change like menu etc.) and one or more individual css file.
Also some images will be include from main theme, other will be individual for modules.
You can use the renderPartial function for load the parts of layout.
<?= $this->renderPartial('webroot.themes.' . Yii::app()->theme->name . '.views.layouts.' . Yii::app()->layout . '.<PART_OF_LAYOUT>') ?>
I disagree that in many help forums of the Internet, when someone asks abot theming a module, everyone suggests a path alias to the themes folder. I think this is wrong, because it implies modules to be splitted, and modules are supposed to be a black-box that can be used across projects. The advice given in such forums would only be valid if a theme is shared among several modules. If someone wants to "package" a theme inside a module, she can:
-add an init function to the controller of the module
-inside that init, use the class attribute layout and a path alias, like this, supose a module whose id is "Sample":
then you add, to SampleCOntroller.php:
public function init() {
//BELOW: it will use the layouts/main.php inside the module.
$this->layouts = "sample.views.layouts.main";
}
Yo can check about path alias here:

All,
Simple question: I want to include an image "logo.png" as the background for my-app. Where should I put the file and how should I refer to it in the CSS file which is in the resources folder along with the main_page.js?
Here is the rest of the story:
I have a CSS class called doc-background. I know this class works because when I set the color of the background in a CSS file like so:
.doc-background { background-color: red} it has the desired effect and Firebug shows me that the class doc-background is being used.
However, when I add a line like
.doc-background { background-image: url('logo.png'); }, there is no effect. Firebug shows that the class doc-background is not applied. And when I modify the style in Firebug to add the line about the background-image it says "Failed to load URL" in the tooltip.
Can someone please point me to a guide on how to work with resources and images and where to put them if I want to use CSS? I have successfully used them using the image-view and coding them into the HTML.
Here is what I have already tried:
Using static-url instead
Moving the image file to images folder under resources
Referred to the image by using all variations on the path - including resources/images only including images, not including either...
Lot of Googling for the answer, Reading create your own app tutorials etc.
If you have an example app that uses colors and images from a CSS that will be the ultimate! But a location and some help with the background-image CSS property will get me started!
Thanks much,
Vis
Place your image somewhere relative to your css:
resources/style.css
resources/images/logo.png
Then use static_url to refer to the image:
background-image: static_url('images/logo.png');
