How to create a good looking site template?

Hi

i recently bought the theme. Could you please tell, how i could create a new page with the red headline box which is used inside the contact forms, matches and sidebars?

Iam speaking about this red headlne box: http://prntscr.com/gsrbs2

After the headline box i want to have a white layer box to insert my content. The goal is to have one good looking page for extra content for tell vistors more about us, our games, servers and stuff like this.

Every basic page does not have any title and of course no styling.
