Multiple callouts - One-Page Site

Is there are a way to put multiple callouts with images alternating left and right on this skeleton?

Yes, you would just need to create more 'text' modular sub pages, and alternate between left and right by setting the image_align option in the page header.

Do I create more text.md files in the _callout folder? or do I create more folders on the _callout folder level e.g. _callout2 and put stuff in there? How do I rearrange the items in modular.md. I get an error when I try to add _callout2 to it.

Thanks

more folders, each with test.md files. Each modular folder should be prefixed by _ to indicate it's a modular subpage.
