Change Leave a Reply and Previous/Next Post Font

I’d like help getting CSS to change the font of the “Leave a Reply” and the font of the previous and next post toggles at the bottom of my blog posts. I’d also like to make the toggle to go back to the previous post larger so it would say “Getting Out of Your Comfort Zone” in a larger font. Here’s a link to my page to see. Everything else is in Georgia except these two things.

Hey there,

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

/*left post navigation*/
#main > nav > div > div.nav-previous > a {
    font-family: "Montserrat", sans-serif;
    font-size: 15px;
/* Right navigation */
#main > nav > div > div.nav-next > a{
    font-family: "Montserrat", sans-serif;
    font-size: 13px;
/* Leave a coment */
.comment-reply-title {
    font-size: 16px;
    font-family: "Montserrat", sans-serif;

Best regards,
