Assign template styles to Joomla Contact Form/Modules/Componentes

Hello,
i'm very impressed how good the template is. But in order to continuos using  the template and forward to the customs some changes must be realized.
In my case Joomla (3) or the template don't assign automatic the styles to the contact form. System displays a page without styles. No margin, no padding for example.
Can you tell me where can i set this changes? In the template Polygons - DEMO it is nice displayed, under menu item "contact" and this is the joomla contact form. So look it is.
The same case for a installed component JEvents but in this case can i understand, when is a third extension.
my site:

DEMo Polygons:

to this:

to add padding to the contact and event pages containers.

Oh yes, it's works fine. Sorry for my english, i'm southamerican living in Germany. My english is not much more good.
It is the same rule for all modules/components?

.item-page, div.contact, div#jevents, div.#any { padding: 0 35px; }

i mean for the next possble.
