How can I change the font of the element p?

Hello,

when I insert the element p in the body of a topic the font is times new roman. All other elements have
other fonts. I want to change the font of the element p.

- I open the template and the topic.template and create a new format for a paragraph.
- I open the EDD and create in the section body elements a new TextFormatRule:
- Section body elements
- Element Tag p
- Container
- TextFormatRules
- ContextRule
- If
- Specification body
- ParagraphFormatting
- ParagraphFormatTag .... name of the paragraph format I create in the template

But it doesnt work the format of the element p is still times new roman.

If I do it that way, I have to create a TextFormatRule for every element (body, section...). Is there
an easier way to say, if all the TextFormatRules in the EDD are false/dont apply then use the textformat xyz.

With kind regards,

Nina
