No spacing between paragraphs

I have created a page in the Poloray theme, and no matter how hard I try there is not spacing between paragraphs. Even when I go into html mode and add paragraph code it still does not work and all paragraphs run together. Why and how do I fix this?

 

Hello,

Use line break tag where you want to break the line.

Code:

<br>

 

Hello Gourav,
how can I resolve the problem on code. The function on visual mode is better for customers.
Thanks and regards
Dante
