Reducing spacing between font types

Hi - Does anyone have an idea on how to reduce the spacing between a header and paragraph section?  Shift + enter changes it all into one type.  Thank you!

You may want to try margin top reducing

To add CSS, go to Design -> Custom CSS
 

.html-block h1 {
  margin-top: 0;
}
