    I'm sorry to say but Lightbox embed code is not mobile responsive. 

    However, you can check the workaround that I have in this other post: https://www.jotform.com/answers/755277.

    I will forward this to our developers so that we can add you to users who are looking for making the lightbox more mobile friendly or responsive.

    Hey gibsongrantstyle,

    Our UI developers fixed this situation, where the lightbox embedded forms were not responsive.

    You do not need any workarounds anymore. And also, since the lightbox embed code's updated through fetched JS files, you do not need to re-embed anything again. It should just work as responsive, still when you delete the workaround CSS codes.

    We will be still waiting for your response and feedback,
