Since Instagram is a third party embed into Webflow, we aren’t actively working on building out exactly how that will render on Webflow sites. It can be quite challenging to adjust the rendering settings for a third party integration as they can update their systems at any time, which would break the flow on many customer sites.
For more control, I would recommend considering the use of an Instagram ➞ New Webflow Collection item flow (this would give you full control of how a collection list of data from Instagram would render on your Webflow site): https://zapier.com/app-directory/instagram/integrations/webflow
However, it looks as though you found a third party solution for the embed and that is rendering quite nicely on your site.
You mentioned that I am using a third party integration, what do you mean?
For the examples given above I am simply pasting the link to the Instagram image into the CMS in the “embed rich content” option.
I imagine the way I have outlined is the only way to have the Instagram embed at a specific part of the post that I like?
