Adding a line under menu items on current item and on hover

Hi all,

A bit of a noob question.

I'm currently working on customising a theme, and am trying to change the look of the main menu. It currently displays a solid colour background behind both the current page title in the menu, and behind other menu items on hover. You can see it here:


I need to change both instances to a coloured line underneath the menu items (and remove the coloured background).

This image shows the effect we need:


I imagine you would use something like:

border-bottom: 2px #f62e9b

Would this be on the right track? I also for the life of me can't figure out what section of CSS is controlling the current page and hover menu functionality.

If anyone can point me in the right direction, it would be appreciated.

Thanks all.

You can do something like the below.

.sf-menu li:hover,
.sf-menu li.sfHover,
.sf-menu li.current-menu-item {
    background: none;
    border-bottom: 2px solid #f62e9b;

To keep the animation you can change the following

.sf-menu li {
    -webkit-transition: background .2s;
    transition: background .2s;


.sf-menu li {
    -webkit-transition: border .2s;
    transition: border .2s;
