This is a Headline

You can see tags only if you switch to HTML-Mode by clicking this button:

Änderungsmodus

Be careful what you do in HTML-Mode, because it can mess up your site. To create a new site without the Menumanager just write your new headline where you want to split or create a new site, mark your new text and press the 
Überschrift 1 or Überschrift 2 or Überschrift 3 buttons.

You have then created a new page within CMSimple.
