Embed Third Party Iframe

Hi there,

We’re trying to embed a third party iframe in a post but it’s not showing properly on the post page (please see link below in the private content area). The iframe should display 3 columns of items but it’s only showing 1 column, perhaps because it is responsive and the width of the content container is below a certain limit?

We tried the same code on an Enfold page and it works fine, but it’s only displaying one column on the post, which is why we assume the issue is related to the width of the container in the post.

Is it possible to expand the content container width on this post alone to be above a limit that would trigger the responsiveness of the iframe (is this possible with Quick CSS?), assuming the issue is indeed the container width.

I’ve pasted below the iframe code as well in case you need it.

Appreciate any help you could provide on this issue.

Many thanks.
