How to remove underline from title and navigation

My page title and navigation field is now underlined. It wasn't yesterday. The odds are it was something I did but having trouble finding a solution. Did a search. Any help is appreciated.

Try this to Website Tools > Custom CSS

a#site-title, nav.header-nav-list * {
	border: none !important;
	text-decoration: none !important;
	background-image: none !important;
}

if it doesn' work, you can share site url, we can check easier
