Is there a way I can make headed bio text larger on desktop and keep the mobile view untouched. 

A code that will allow me to adjust the sizing myself would also be very helpful  but if not can I just have it larger.

Thanks for your help!

Add the below code in Page Settings -> Advanced -> Page header code injection.

You can adjust the font size to the one you want

<style>
@media (min-width: 768px) {
    #sections > :first-child h3 {
        font-size : 40px;
    }
}
</style>

Thank you mate! 
 

I’ll give that a try, thank you so much
