Predictive content for media queries - background code

Hi all

I've seen Marketo's predictive content tool through a webinar - you right click the content in the editor and click "Make Predictive." But how would this work if you want to use media queries, and switch content in and out?

Hopefully, there is a bit of code which you can use in Dreamweaver or similar to use predictive content and also control the size of the image and sub in and out content with media queries. Otherwise it's a bit restrictive - we code in Dreamweaver and import into Marketo, and never use the editor except to insert code.

Thanks!
