Changing H2 size on MOBILE ONLY - CSS code needed

Hi 

I have followed that many tutorials today with coding and nothing is working 😞

I am only wanting to change H2 on home page of mobile - "let me help lighten your load" to a smaller sized header as looks so out of whack on mobile version but perfect on desktop. 

Any help with code to copy and paste would be super duper appreciated. 

Need the URL to the site to fix this...

You can try this to Design > Custom CSS

/* Mobile h2 */
@media screen and (max-width:767px) {
	body.homepage h2, body.homepage h2 * {
		font-size: 12px !important;
}
}
