How to use a custom blog page template

Go to Divi Theme Builder >> Build New Template 

Select Blog (This would override the current assignment that comes preassigned with the child theme) >> Create Template

To load the layout from the library click on the Add Custom Body then select Add From Library.

Choose the option Your Saved Layouts >> Mark the category Blog And Archive Layouts then choose any blog template you want to apply on your website’s blog page.

Save Changes.

That’s it!!!
