Are Layouts and Sections compatible with the Divi Builder Plugin?
All Layouts and Sections are compatible with the Divi Builder plugin v3.25+.
The Divi Builder Plugin v4.5.1, has a bug that overwrites Section custom width percentage settings if a background color has been set. For example if a Section has a custom width of 50% and a dark background color, the width will always be set to 80% instead of the custom width in the Sections settings.
Elegant Themes are aware of the bug however there is no ETA on a timeline for this fix.
This article will be updated as soon as the fix has been released.
Workarounds
Until a fix is out, you can set the width to 100% and then set the max-width to your custom width setting.
