Need to remove rules under all links

Site URL: https://tomato-ellipsoid-sa98.squarespace.com/config/design/

My links to phone numbers, email addresses, and partner businesses are all underlined. How do I get rid of those? I found one bit of code for footers but this info is in the body of the site pages. Rules seem to be randomly applied.

Thanks.

Add to Design > custom CSS

/* remove underline */
#page a {
	background-image: none !important;
}
