#mainnav .current-menu-item section

Hi,

I am trying to build a website with multiple sections on one page and have each section listed as a menu item. Ideally, I only want the relevant section underlined when selected or scrolling. Also, how do I keep “home” as a menu item and not have it underlined?

The code I am currently using in the additional CSS is;

#mainnav .current-menu-item {
	border-bottom: 2px solid #d65050;
	color: #d65050;
     font-weight: bold;
}

TIA
