Question:
since Joomla! 1.5 is an MVC content management system and provides means to "override" default HTML layouts within a template's folder, I wanted to know if any of the youjoomla template (like Younews) already have a K2.css override?
A-What I'm trying to achieve with joomla K2 component and a Youjoomla template :
The website I am building uses the one and only Youjoomla template

and has 3 major areas : news section, a knowledge base section, and a forum section. The K2 component will allow me to simply duplicate a template folder on the server within my main Joomla template - thereby creating another template to work with. That is, the K2 news section is different from the K2 knowledge section or the K2 forum section and so on.
B-What was recommended in using this component :
In order to use the K2 joomla component, and achieve the above, one has to usually copy the "tmpl" folder of a component's view within the Joomla! template's. Thus,I followed these recommended steps:.
Step a- Create a com_k2 folder.
1-create a folder called "com_k2" within /YOUJOOMLATEMPLATE/html/com_k2/
2-copy "default" folder found within the /components/com_k2/templates/ and PASTE it into /templates/YOUJOOMLATEMPLATE/html/com_k2/
3- renamed each "default" folder after sections I wanted.
Step b- K2.css.
Upload/copy the k2.css file from component/com_k2/cssthe to the templates/[your template name]/css folder.
Note:
The reason I asked the above is because if for example, the template Younews, or any youjoomla template, for that matter, already has a K2 override, its recommend that I just upload the contents of the html/com_k2/templates folder otherwise I will overwrite any existing k2 template.
