i just ran into the same issue. I’m not webdev person, so any css hacks i’d attempt would be terrible, but i did find the file /srv/bench/erpnext/apps/frappe/frappe/templates/pages/integrations << stripe_checkout.css and .html. your folder will of course depend where you installed. but per this thread, Build.json and custom CSS - #2 by revant_one i think directly modifying these files is not recommended, and doing so may break your erpnext updating. I DID just modify the stripe_checkout.html, to see if it works, and it does. please share if you come up with a good fix.
