CSS code needed for Hensen Template for Index Settings > Page Description

My site is not live yet as I'm doing a complete portfolio overhaul. My template is Hensen. I'm just tryng to bring in my custom fonts and I got it to work for my site title and tagline using this code:

.site-tagline {
    font-family: 'billion_reach_demoregular' !important;
}

I am looking to adjust the Index > Page Description, the main text on my site homepage (work), with the same custom font I used for my tagline. It's the main centre text in the screenshot below (set in Timberland font currently) 

Any help greatly appreciated! Thank you!
