I am working with a theme called Divi from Elegant Themes. I wanted to see if anyone could help provide me some insight about how to reduce the blank space that shows up between the sections on the page? Overall I am creating a new Landing Page Template that you can see here and there is way too much space showing up by default as you can see on this page: http://bit.ly/1GtY77h
Overall I know I would go into the CSS section to adjust the spacing, but I am not sure for which reference the spacing would be listed under. Any assistance would be appreciated. Overall I have added a child theme to the site so I would plan on adjusting this style.css file so that if / when I am updates to the theme these adjustments I have made won't be affected by me doing the update.
Thank you for any insight you may be able to provide.
