Change Title/Heading Font Size - Dawn Theme

Store Design
1

Hello,

Searching for a solution to change the title/heading font size in the Dawn Theme.

I’ve changed the body text font size with the code below but now I’m wondering how to change the title font size.

@media only screen and (min-width: 750px){
body {font-size: 1.2rem !important;}
}
@media only screen and (max-width: 749px){
body {font-size: 1.2rem !important;}

Thank you!
