Auto resize iFrame

[wortberge]

A customer uses Lightcase on their website. Now we need a way to set the height of an iFrame depending on the content, like it would be possible with Fancybox 3. I need to be able to specify the maximum width. How can I implement this?

```
maxWidth:1920,
maxheight:1080,
