Equalizing column heights in Divi driving you crazy?
Getting your columns to be equal heights in your Divi Theme is quite simple to do, but there is a common mistake that people seem to be making that results in un-equal column heights. That mistake is to add the background colour to the modules within your row, rather than the columns within the row itself.

The key to getting the equalized column heights is to add the background colour within the rows advanced design settings rather than adding a background colour to the actual modules within the row.
