How do I edit html/css of a specific page?

Hey, I’d like to edit the link properties of a specific page so they direct elsewhere than what I specified in the social settings menu, which works globally. So, as it is now the links inherit their properties and theres no way in the cms to change this for every page. Is there a way to add it in the css? I’m not sure how to format it correctly. Here’s the hmtl:

The page id: body.page-id-85

<div class="wrapper">
	<div class="thb-social-home">
		<a title="Facebook" href="https://www.facebook.com/">
		   <span class="thb-social-icon">2</span>
		</a>
		<a title="YouTube" href="https://www.youtube.com/">
		   <span class="thb-social-icon">5</span>
		</a>
	</div>
</div>
