Answer 1

This snippet will be useful

HTML

<ul id="menuList">
<li><a href="home">Home</a></li>
<li><a href="gallery">gallery</a></li>
<li><a href="about">about</a></li>
<li><a href="contact">contact</a></li>
</ul>

JS

$('#menuList li').click(function(e){
 e.preventDefault(); //Remove this in your main code
    $('#menuList li').removeClass("active");
    $(this).addClass("active");
});

CSS

.active{
    background-color:green;
}

WORKING EXAMPLE

Answer 2

Give a class or ID to the ul . Then, assuming jQuery and an ID of nav :

$(function() {
    $('#nav a[href^="/' + location.pathname.split("/")[1] + '"]').addClass('active');
});

All you need then is to style the .active class. Also, this assumes your links are /my-page , so if you are currently in my-page , the link will become .active .
