Need help customizing code for text rotation on mobile

Hey all!

I used the below code I found online to rotate a small section of text in the footer of a site I am working on. However, I need to UNDO the rotation on mobile for it to look right and can't figure out how to update the code to revert back on mobile. 

#block-yui_3_17_2_1_1707432821850_197215 { transform: rotate(-90deg);}
 

Here's the site:
