A couple things you can do to (fix) customize your needs.
1. You can place the following code in your
additional.css for your style. It changes the font:hover color for the popupctrl.
Change "#ffffff" to whatever color you need.
Code:
.navtabs li.selected li:hover a.popupctrl {
color:#ffffff;
}
2. Also add this code to your
additional.css of your style. 8px is a good starting point but you can adjust as needed.
Code:
.globalsearch .textboxcontainer span {
padding-top: 8px;
}
Hope that helps.
