Why doesn't overflow: hidden work in Safari?

Question

css

Actually I encountered such a problem, in all browsers, everything works fine, but in safari it doesn’t want to and it turns out to be a whirlwind, are there any solutions?
And the second question, is there any thing that emulates the safari browser, which would be more convenient to test?
PS I do not own macos

Answer 2

if you want to check for cross-browser compatibility, then either have a real device or a virtual machine,
no emulators behave like a real browser in a real environment
