Divi is actually pretty good. Despite all it can do it still loads quickly. There are a few default CSS styles that are odd / don’t seem right.

I’ll update this as as find more but so far:

In default, phone icon is 1px too high and 3px too close to text. Fix:

#et-info-phone:before { top: 1px; margin-right: 3px; } 

Remove vertical gray sidebar line on blog page:

#main-content .container:before { background-color: transparent; }
