I'm having this website on joomla framework http://carhitz.com/ I want to add some new buttons and new divs to different pages of my website but I can't find the source code of individual pages. I know that they're in the components folder with something like com_(something) but I really can't figure out which component file points to which page. For eg: I want to find the php file containing the content of the following link:
http://carhitz.com/lighting-gallery
But I can't find that component or whatever file that is used to generate all those sculpture gallery items. DOes anyone have an idea where can I find them? I'm using hexeris theme.
Joomla! does not work like pages in some folder, the content is generated by menu items, components or modules.

If you need change something in this component, you need an override, here you have the
