Harlowe and Mobile Text Sizing

I've noticed when I open my harlowe based game in my mobile, some pages show incredibly small text. This doesn't seem to have any rhyme or reason to it. I deleted my CSS stylesheet to see if this was affecting it, but the issue persists.

The game looks awesome on the PC, but I'd really like it to look just as good on mobile. Does anyone know what this issue is, and if so, how to solve it?
