Images won't go vertically in Product Description in Davinci Theme


New Member
Hi there,
I'm trying to format my product descriptions in order to optimize them for conversions and better fit my main photos for Google Shopping ads. The formatting doesn't seem to transfer out of box, and after trying to add bootstrap to the page is still isn't working. Is there any way to format the product description?

i.e. this:

gives me the same output as it would without any formatting at all. It will only allow pictures in the product description to be stacked vertically, never horizontally.

Is there any way to better format the product description? I'll even switch themes if necessary. Landing page is everything for conversions!
