Need Help Figuring Out Admin Menu Hover Styling Class

#adminmenu li.menu-top:hover,
#adminmenu li.opensub>a.menu-top,
#adminmenu li>a.menu-top:focus {
    position: relative;
    background-color: #191e23;
    color: #00b9eb;
}

Make sure your plugin is using the structure:

<li> <- position within admin menu is as a list item, using the <li> tag.

    <a>LINK</a> <- main link

    <ul> <- submenu container
        <li><a>submenu item here</a></li>
    </ul>
</li>

ofc dont put anything with those <- bits inside the code, it’s just an example of structure!
Hope it helps
