How to add spacing between fixed navigation and call for action section?

hello, first thank you for this “great theme”. Fast loading and clean. I’m having trouble editing the codes. The main menu and the first post on homepage are overlapping. May I get the right code to add to css to fix the spacing? this is my blog:

and is there a possibility to add dividers to widgets? thanks.

I see that you followed one of the tutorials here on the forum on how to make fixed navigation for Sparkling theme but didn’t follow all the steps mentioned on that tutorial.

You have forgot to add this code to Theme Options - Other - Custom CSS

#content {
  margin-top: 76px;

Thank you very much! I’ll make donations in the future!
