Flip box

I have a flip box on my website and I’m trying to inspect the back of it to change the font size but it seems impossible because when I click on it to inspect it doesn’t flip over!
Any ideas?? Thanks

It can’t be done in the dashboard?

I made it responsive in the dashboard as much as it allowed but I need to fix something on another device that they don’t give the option for so I’m doing it with CSS… but I’m a bit stuck now

If you want to see the over state you have select it from the above
