Block: Before & After
From Posstack.com Documentation
Before & After slider block lets you compare two versions of an image together. Before and after images will appear with a divider which can be moved so that users can see the difference.
NOTE: This block is only available for the Pro plan. You can still add and edit this block normally in the Theme Editor; however, you need to upgrade your plan to apply them to the front end.
If you are new to our Easy Content Builder, please take a look at the Add Sections section for detailed instructions on how to add a section to your theme.
