Fluid Engine mobile text block grow/shrink not working

I have a client site that I recently built almost entirely on Fluid Engine. We started noticing some minor styling idiosyncrasies that seem to be bugs in the core functionality of Fluid Engine. This issue is essentially that the mobile design assumes a very narrow/lo-res mobile screen, so the text box takes x number of rows (in our case, it's around 25, I think). When a mobile screen is wider, the text obviously takes up fewer rows/less vertical space, but the text box in Fluid Engine stays the same size (25 rows), pushing the rest of the content down the page, below some white space. 

See attached screenshots for a comparison of narrow mobile to wide mobile views. 

Please let me know if anyone knows a fix or hack for this! The CSS fix wasn't immediately apparent from playing with Chrome dev tools. Input from SQS folks would also be great!
