Stripe credit card fields too small to enter information

I’m setting up Woocommerce on a site using Stripe as the method of payment, however on checkout the area where you enter credit card details is too small (i.e. very narrow) so you can’t actually complete the fields. I’ve tried some suggested solutions here and in other forums but with no luck.

It’s a Divi theme – I’m sorry I’m not really sure what other information to provide (I’m new to this).

Grateful for any help.
