Circles in navigation and active on hover

I'm trying to achieve this effect in the header of circles next to navigation items and then they become active on hover?

Cheers!

@tuanphan Are you at all able to help with this?

Thank you!

Hi,

What is your site url?

For anyone interested with this effect. Use this code to Website Tools > Custom CSS

div.header-nav-item>a:before {
    content: "";
    width: 10px;
    height: 10px;
    display: inline-block;
    border: 2px solid #fff;
    border-radius: 50%;
    margin-right: 5px;
    position: relative;
    top: -2px;
}
div.header-nav-item>a {
    align-items: center;
    display: flex;
}
div.header-nav-item--active>a:before, div.header-nav-item>a:hover:before {
    background-color: #fff !important;
}
