How do I change the font of a specific block/section of a page?

Hello,

I am trying to change the font of a specific section without changing the font style of the entire site. I know there is some coding required and I have zero experience with coding. I have seen some codes on google but I have no idea how to use it... Would appreciate any help with this. Thank you in advance!

Hi,

Can you share link to page & let me know which section you want to change? We can help easier
