/* Change Font Family in WordPress Comments */
#author, #email, #comment, #url, #submit {
font-family: inherit;
}Add the above CSS to your child theme’s style.css. This will change the font-family of the ‘WordPress Comments‘ to the body font family of your site. However, you can change the font-family if you need, replace ‘inherit‘ with font-family you wish to have on your Comment Form.
