[SOLVED] Single Posts "squished" to the left in Mobile

I just switched to Montezuma for mobile only (I'm still very attached to my Atahualpa, but needed a dynamic theme for mobile). The category lists, etc. are working beautifully - it's just the individual posts where it's a problem (I'm also having an issue with the home page, but I suspect that's a caching issue and I'm not worrying about it right now). I've played around with the single.php template enough to narrow the problem down to the php content, but I'm not sure where to go from there. My Content CSS is unmodified from the default, except from one small change in color.

I'm far from an expert in CSS, but I have so far managed to jury-rig my site so it works well enough.
