How to modify the templates in the listing templates extension
All the templates that are in the Listing Templates extension can be overridden when placed into your active theme. Once the files are in your active child theme they will be used instead of the files that come with the plugin.
Copy the templates from plugins/epl-listing-templates/templates/content into the /easypropertylistings directory of your active theme.
You can now make alterations to the items on the template to suit your designs.
The plugin has minimal CSS so you can apply your own CSS to suite your design by either adding a custom style.css file in the /easypropertylistings folder or use the Additional CSS in WordPress 4.7+ Customizer.
