Use a different font on just one page of a Squarespace website without affecting the other pages

Hi,

On my Squarespace website i have one page that will be a landing page for ads. For this page I need to use a different font set to the rest of the site (one of the ones in Squarespace). I've been pulling my hair out all afternoon trying to do this but can't figure out how to change the fonts without it affecting all the fonts in the website. For example when I change the paragraph font, it changes for all the paragraphs in the website, but i just want to change the paragraph font and header fonts on this one page. 

Any help much appreciated.

If 7.1, you can use a specific theme style on this page, if 7.0, can you share link to this page? We need to use code to assign different font

@Natal Can you share your page URL that you're referencing? It's not possible to assign a different paragraph font, this is a global style change that affects all pages on your website. As the other member mentioned, you'd need to target that specific paragraph using CSS. 

Thanks i've resolved it now. I ended up changing the global font style to a better one that suited all pages.
