<jdoc:include type="modules" name="contenttop" style="xhtml" />
9. Menu items create a content view
logo headerleft headerright
left Component right
area
left2 left3 right2 right3
contentbottom
footer
The content view can contain a single article,
a category listing or similar, i.e. an output from some
component in Joomla. Content from this component
is shown in the component area of the template.
10. Modules shown for this menu item
logo headerleft

right right
Component
area
left2 left3 right2
contentbottom
footer
Modules can be linked to the content view.
In other words, the modules are linked to the menu item.
11. Where modules are show is
selected in the module itself

area
left2 left3 right2
contentbottom

In Joomla 2.5, modules can be shown on All Pages,
No Pages, All Pages Expect Selected or All Selected Pages.
12. Modules normally fill the space they have available

This depends on the way the template is coded.
