On a mini (latest Safari), it's pretty hopeless. Can't see prices, can't type in search. Being catty, it's junior college time. Then there's new collections where you have to squint at the picture to see what's included (https://www.logos.com/product/49776/select-works-of-john-dominic-crossan). I don't even like Crossan. And so airy too. Oh my ... it's in english!!
I don't use either but possibly you have Desktop Mode on for the site.
If your screen is that narrow, it should change to the mobile site, although on my android phone using firefox, if I do use desktop mode, it just zooms the whole screen out so very small, but still complete not cutoff.

Thank you, Kevin. Although workarounds are a common theme-song in Logosland. They fixed it not long after this thread.
Of course, they currently have the exact same issue on their app.logos.com. Like many on the forum, I do web coding, and it's not hard to guess what code checks they left out.
Many moons back, I developed neural software that could evaluate the intelligence or work habits of a competitor's buyers (and quickly shift pricing/assortment strategy). I suspect this type of machine learning is also appropriate to web coder prediction.
