HTML file incorrect character style

Hi!

Can anyone help me with something?

Whenever I upload and URL on my laptop from the website I created in Xd, I can see the correct character style on the letters. However, when I place the code into Dreamweaver and than save that file, also html and send this to my Iphone, Character style becomes default, native and incorrect. I just 'Muli'.

Do I need to make a saperate style sheet code for Dreamweaver? 

or

All my text is put in als <div> instead of <p>, done by Xd. I must change it al to the P in order to let it work?

Advanced thanks!
