Changing font size for mobile

Site URL: https://www.ambiancecurator.com/

Hello, I am trying to use the code below to optimize my font size on the mobile display. For some reason it is not picking it up. Could this be because I already have a custom CSS code for a custom font? How can I code this so that the mobile layout responds to the code?

@media screen and (max-width: 641px) {
body {font-size: 11pt}
h1 {font-size: 13pt}
h2 {font-size: 13pt}
h3 {font-size: 16pt}
}

Hi. Add above code to Design > Custom CSS

@media screen and (max-width: 641px) {
body {font-size: 11pt;}
h1 {font-size: 13pt;}
h2 {font-size: 13pt;}
h3 {font-size: 16pt;}
}

I have the same issue, font size is to big on my mobile menu and the css isn't working. www.rabbiasukkariehart.com
