    border: none;
    cursor: pointer;
}

.dropdown {
    position: relative;
    display: block;
}

.dropdown-content {
    list-style-type: none;
    display: none;
    position: relative;
    right: 0;
    background-color: black;
    /*background-image: url('../../Images/black-olive.jpg'); dropdowm popup*/
    min-width: 160px;
    box-shadow: 0px 8px 16px 5px rgba(0,0,0,0.2);
    z-index: 0;
    padding-right: 2px;
    margin-right: 2px;
}

    .dropdown-content a {
        color: white;
        padding: 10px 14px;
        text-decoration: none;
        display: block;
    }

        .dropdown-content a:hover {
            /*background-color: gray;*/
            color: black;
        }
