Hi all!

I'm currently running into a problem that may be very niche (or maybe not!). I'm hoping someone has the expertise to help me out. 

Attached are two different screenshots from two different phones. As you can see, Golden Oaks Developments is perfectly fine on my iPhone 14. But my friend who has an iPhone 13 shows the "s" in Golden Oaks Developments carrying over to the next line. How am I able to fix this so it views as it should (on my iPhone 14)? 

I've already implemented the following code:

//Change mobile font size//

@media screen and (max-width: 640px) {

  h1 {

    font-size: 2.1rem !important;

  }
   h2 {

    font-size: 1.56rem !important;

  }

}
 

The headings in question are Heading 1.

Thank you!

That's unfortunately what I had expected. Thank you for the recommendation! Seems like the best way to mitigate @CassAggett
