[Theme: X-Theme] Display one logo for desktop and a different logo for mobile?

Hey everyone!

I’m working with a theme called “X” from Themeco for a friend and you need a license to post in their forums (and she bought the theme, so I don’t have the key to verify and make an account) but everyone here has always been so on point with help, I’m posting here.

This is the site: https://www.darkwhitecomic.com/

What I’m trying to accomplish is to display the current logo you see when a user is on a desktop but display a different (smaller) image for the logo when a user is on a mobile device.

Here is the URL for the image I’d like to use for mobile (and yes, I will be scaling it down before using it, I know it’s huge): https://www.darkwhitecomic.com/wp-content/uploads/2016/01/DarkWhite_logoLineV2.png

I’ve tried a few different custom CSS suggestions from other threads but most seem to be theme specific and don’t work.
