Changing HTML for E-Mail Templates

[WagnerVonHagen]

Hello,

i have a problem regarding changing the contents of the predefined Emails (order_conf, password_query, etc.)
I copy the HTML, import it to Dreamweaver. I change Text and Style i want and then paste the code into Prestashop (Frontend).

It looks good before saving.. then all the Formating is broken (see attached files)

I use both 1.7 and 1.6 - same result.

Also happens when i don't edit the code in an external Program.

What am i doing wrong? Is there a css-override somwhere?

 

Maybe someone could help me.
