How to dynamically change the color of the selected menu item of a web page?

Tags: html,css,background-color,menu-items,menuitem-selection

Problem :

I am new to developing web pages. I am looking to create menus similar to the ones in (like Questions, Tags, Users shown above). How do I change the color of the selected menu (for example, the background color of the Question changes to orange when 'clicked')?

I have managed to change the color while hovering (using CSS) as that was simple, but I am having trouble with this.

Can I achieve this effect of changing the color of a clicked item using only CSS?

Solution :

Set the styles for class active and hover:

Than you need to make the li active, on the server side. So when you are drawing the menu, you should know which page is loaded and set it to:

 <li class="active">Question</li>

But if you are changing the content without reloading, you cannot change set the active li element on the server, you need to use javascript:

<script type="text/javascript" src=""></script>
  .menu{width: 300px; height: 25; font-size: 18px;}
  .menu li{list-style: none; float: left; margin-right: 4px; padding: 5px;}
  .menu li:hover, .menu {
        background-color: #f90;

<ul class="menu">
<li>Item 1</li>
<li class="active">Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
<li>Item 6</li>

<script type="text/javascript">

var make_button_active = function()
  //Get item siblings
  var siblings =($(this).siblings());

  //Remove active class on all buttons
  siblings.each(function (index)

  //Add the clicked button class

//Attach events to menu
    $(".menu li").click(make_button_active);
