{
    list-style-type:none;
    float:left;
    border-bottom: solid 2px Red;
    padding-right:40px;
}

    width:auto;
    padding:8px;
    display:block;
    cursor:pointer;
}
</style>

<script type="text/javascript" language="javascript">

    function checklist(ctrl)
    {
       
        var list = document.getElementById("menu").getElementsByTagName('li');
       
        for(i=0; i<list.length; i++)
        {
            list[i].style.background = '#ffffff';
        }
       
        ctrl.style.background = '#ff0000';
    }

    1. Here you go...
      but i have used # instead of ? because this become a query string and the page reloads and as you know javascript is static so it again loads with the page load. So you can use as in the below topic

      Change Css Class of li in ul onclick with Anchor Tag

      Or if you want to use ? then you have to write the code on each page by getting the url and set the button clicked

      For your solution you need to write script on each page that are linked to your menu.
