STYLE FONT CHANGE mobile only

Hello guys! Can someone help me with a css code to change the style of a H2 font a specific page?  I've been trying but cant figure it out. Thank you!!!

I'm not really to sure how you want to stye your H2 but you'll need something along the lines of this...

@media (max-width:640px){
	h2 {
		font-size:20px!important
	}
}

Thank you. Thom! 

On that page I have two block  using H2, is there anyway I can make it affect only one of the blocks font? Thank you 🙂

Yes, I have linked to the below blog post which details how to target a specific block.
