Change the active navbar color in css

I am using a simple top css navbar(just a css and html, without bootstrap/other framework) and i would like to change the active page. So when i go to the home page, the button color in navbar changes into red/whatever, likewise when i go to the other page...
here the code:
body {
margin: 0;
}
.logo {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #f2f2f2;
float: left;
width: 25%;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 40px;
text-decoration: none;
font-size: 18px;
}
li a:hover {
background-color: #111;
}
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>
do you have an idea? it's ok to add javascript
Thanks a lot!

What I did here is when $(document).ready(function() {..} get the path using var url = window.location.pathname; so you know which link the user coming from therefore you know which menu item they clicked.
Then $('ul li a').each(function() {...} will check each menu item, try to match the url path with the menu's href attributes, if a match found, make that menu item active (with css active class added), if not match remove the active class if any. That should do the trick.
(note: assume your app is not single page app)
for Single page app it is much easier, deactive all menu item then active the one you clicked.
$(document).ready(function() {
//var url = window.location.pathname;
var url = 'http://stacksnippets.net/js#division';
console.log('url-->', url);
$('ul li a').each(function() {
var href = $(this).attr('href');
if (!!url.match(href)) {
$(this).addClass('active');
} else {
$(this).removeClass('active');
}
});
});
body {
margin: 0;
}
.logo {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #f2f2f2;
float: left;
width: 25%;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 40px;
text-decoration: none;
font-size: 18px;
}
li a:hover {
background-color: #111;
}
.active {
background-color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>

The simplest solution would be to add an active class to the link of the page you're on:
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>
Then style those that class accordingly:
li a.active {
background: #F00;
}
If you're using a CMS (Wordpress, etc), adding some sort of active class on the active link is usually done for you. If you're doing your own static HTML, you would have to do it manually.

try below code for active menu
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('li a').on('click', function(){
$('li a').removeClass('active');
$(this).addClass('active');
});
});
</script>
<style type="text/css">
body {
margin: 0;
}
.logo {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #f2f2f2;
float: left;
width: 25%;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 40px;
text-decoration: none;
font-size: 18px;
}
li a:hover, li a.active {
background-color: #111;
}
</style>
<ul>
<li>Home</li>
<li>News</li>
<li>Contact</li>
<li>About</li>
<li>Division</li>
<li>Career</li>
<li>MChoice's</li>
</ul>

To change the color of active link in your navigation you need to do the following things:
On click of navigation link add css class:
$('ul li a').click(function(){
$('li a').removeClass("active");
$(this).addClass("active");
});
Add CSS for active class
ul li a.active {
background-color: #f4f4f4;
}

One possible way is to use the active selector in CSS. This selector highlights the active element you are using when its clicked.
a:active {
background-color: yellow;
}
a:focus {
background-color: yellow;
}
You can use some JQuery to turn it on and off too. Try looking at this post here, I think you may have get your answer.
(Related to How to keep :active css style after clicking an element)
jQuery('button').click(function(){
jQuery(this).toggleClass('active');
});

function redButtons() {
$(".inclusive-buttons").on("click", "a", function() {
$(".inclusive-buttons a").css("background", "#333");
$(this).css("background", "red");
})
}
var x = document.getElementsByTagName("li");
x.onclick = redButtons();
body {
margin: 0;
}
.logo {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #f2f2f2;
float: left;
width: 25%;
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 40px;

font-size: 18px;
}
li a:hover {
background-color: #111;
}
a:active {
background-color: red;

here is JSFiddle result
http://jsfiddle.net/Ag47D/775/

Here's a JSFiddle: https://jsfiddle.net/timhjellum/nw3n7eka/103/
This is a jQuery option which looks at the page URL (window.location) and specifically for a string which you define in the .indexOf(" add a unique string here ") and asks if that string is greater than -1, then locate the li element with the class you assigned to it, and add another class called active.
In the example I'm using "display" because that the URL for that iFrame that JSFiddle uses so hopefully that's not confusing.
Here's the navigation:
$(document).ready(function () {
if(window.location.href.indexOf("home") > -1) {
$(".home").addClass("active");
}
if(window.location.href.indexOf("display") > -1) {
$(".news").addClass("active");
}
//make one for each nav element
});
The HTML needs to be modified like:
<ul>
<li class="home">Home</li>
<li class="news">News</li>
<li class="contact">Contact</li>
<li class="about">About</li>
</ul>
And then a simple css addition:
li.active {
background-color: white;
}
li.active a {
color: black;
}
If you can't use jQuery, let me know but this is the easiest solution for you to implement and allow you to easily modify

You could try having separate classes in your CSS file, like "ul-home," "ul-news," etc. and define different background colors for each, then simply set the class for your <ul> tag on each page to match the class you want. So:
.ul-home {
background-color: red;
}
.ul-news {
backrgound-color: yellow;
}
And then on your home page:
<ul class="ul-home>
<li>Home</li>
<li>News</li>
</ul>
On your news page:
<ul class="ul-news">
<li>Home</li>
<li>News</li>
</ul>
Etc. with all the other pages you have.

Attach event handler to every li

I have this code and I want to attach DIFFERENT event handlers to every <a> without using id or class.
I tried this but didn't work...
$('#points ul li a').on('click', function(event) {
// I don't know why this selectors doesn't work
if ($(event.target).is(':eq(0)')) {
alert('0') // and do something
}
if ($(event.target).is(':eq(1)')) {
alert('1') // and do something
}
if ($(event.target).is(':eq(2)')) {
alert('2') // and do something
}
})
#points ul {
list-style: none;
font-size: 5em;
padding: 0;
margin: 0;
line-height: .5em;
}
#points ul li {
float: left;
}
#points ul li a {
text-decoration: none;
color: grey;
padding: .1em;
line-height: .1em
}
#points {
position: relative;
margin: 0 auto;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="points">
<ul>
<li>.
</li>
<li>.
</li>
<li>.
</li>
</ul>
</div>
<script
Thanks in advance.

As suggested there are many alternate solutions, but the specific
error in your code was regarding your usage of :eq(0). Change it to #points>ul>li>a:eq(0) as per the jQuery documentation .
REPLACE
if ($(event.target).is(':eq(1)')) {
WITH
if ($(event.target).is('#points>ul>li>a:eq(0)')) {
Note: I have used #points>ul>li>a so that other <a> tags above and below are not selected. ( in light of your comment regarding the same )
I want to just add that if I was asked to do the same I'd take an
approach like:
var objArr = $('#points>ul>li>a');
objArr.on('click', function(event) {
switch($(objArr).index(this)){
case 0:
alert('0');
break;
case 1:
alert('1');
break;
case 2:
alert('2');
break;
}
});
That said your method works too and the WORKING EXAMPLE with the error I mentioned above adjusted for:
$('#points>ul>li>a').on('click', function(event) {
// I don't know why this selectors doesn't work
if ($(event.target).is('#points>ul>li>a:eq(0)')) {
alert('0') // and do something
}
if ($(event.target).is('#points>ul>li>a:eq(1)')) {
alert('1') // and do something
}
if ($(event.target).is('#points>ul>li>a:eq(2)')) {
alert('2') // and do something
}
})
#points>ul {
list-style: none;
font-size: 5em;
padding: 0;
margin: 0;
line-height: .5em;
}
#points>ul>li {
float: left;
}
#points>ul>li>a {
text-decoration: none;
color: grey;
margin: .1em;
}
#points>ul>li>a {
background-color: yellow;
}
div {
margin-bottom: 50px;
}

}
if (el.is('a:eq(1)')) {
alert('1') // and do something
}
if (el.is('a:eq(2)')) {
alert('2') // and do something
}
})
#points ul {
list-style: none;
font-size: 5em;
padding: 0;
margin: 0;

}
#points ul li {

stopping dropdown navigation bar from pushing elements aside

I have a dropdown navigation bar, and when elements like buttons or images are too high up on the page, the navigation bar pushes the elements to the right side when drop-down options appear. How do I stop this?
Navbar:
<nav id="nav1">
<ul>
<li>Home</li>
<li onmouseover = "DropDown1()" onmouseout="DropUp1()">Images<ul class="DropUp" id="Droplist1" >
<li class="DropDown"><a id="Droplist1" href="#">Test1</a></li>
<li class="DropDown">Test2</li>
<li class="DropDown">Test3</li></ul>
</li>
<li onmouseover = "DropDown2()" onmouseout="DropUp2()">Adverts<ul id="Droplist2" class="DropUp">
<li class="DropDown">Test1</li>
<li class="DropDown">Test2</li></ul>
</li>
<li>Data Validation</li>
<li>Security</li>
</ul>
</nav>
CSS:
nav#nav1 li a {
display: block;
padding: 3px 8px;
background-color: #5e8ce9;
color: #fff;
text-decoration: none;
}
nav#nav1 li {
list-style: none;
float: left;}
.DrowDown {
display: block;
position: absolute;
margin: 0;
padding: 0;
float: none;
}
nav#nav1 li:hover li {
float: none; }
nav#nav1 li:hover li a {
background-color: #69f;
border-bottom: 1px solid #fff;
color: #000; }
#navbar li li a:hover {
background-color: #8db3ff; }
nav#nav1 ul li a:hover { background: #686868 ; }
nav#nav1 ul li a:active { background: #F0F0F0; }
JavaScript functions for dropdown:
function DropDown2() {
var t = document.getElementById("Droplist2");
t.className = "DropDown";
}
function DropDown1() {
var t = document.getElementById("Droplist1");
t.className = "DropDown";
}
function DropUp2() {
var t = document.getElementById("Droplist2");
t.className = "DropUp";
}
function DropUp1() {
var t = document.getElementById("Droplist1");
t.className = "DropUp";
}
If you are wondering why I took such a difficult route for making the navigation bar, it's because I have to use JavaScript.
Here is JS fiddle example: http://jsfiddle.net/fNPvf/10015/
The window is small in the fiddle, and the effect is slightly different, but notice how when you hover over "Data Validation" the dropdown menu pushes the text/image/body downwards?

You need absolute positioning and a higher z-index for either the containing <div> or the <ul> itself. Just add this to your code and adjust the z-index as needed:
nav#nav1 ul{
position: absolute;
top: 0;
z-index: 9;
}
See working demo here

Dynamically set width of li to match width of parent ul

I am making a drop-up using li nested in ul but am not able to set the width of li to dynamically match the width of the ul.
Please note that the li elements are constricted within a drop-up list.

The width of the li seems to be the same as the ul by default.
Atleast based on my experiments here http://jsfiddle.net/dwCsW/
If you remove the ul width it will be 100%, and by setting ul width the li will follow.
So there must be something else in your code removing that.

You could either give the li's a percentage width in the css... there are 7 of them, right? so maybe make each 10% wide, put 4% between each one and 3% at the beginning and end? Or, you could use JavaScript and detect the page resize event, then get the page/ul width and set the width of each li item using some good ol' fashioned number crunchin'!

as you can see the 3rd level "Mession Statment 1" doesn't appear, and that's my problem, any suggestion ???

The problem is maybe due to these lines
$('#jsddm > li').bind('mouseover', jsddm_open);
$('#jsddm > li').bind('mouseout', jsddm_timer);
in which you set an event handler only to the direct <li> children of #jsddm element. But your third <ul> is not contained in a such <li>, so try to change the above lines in
$('#jsddm li').bind('mouseover', jsddm_open);
$('#jsddm li').bind('mouseout', jsddm_timer);
and
function jsddm_open() {
...
ddmenuitem = $(this).children('ul:first').css('visibility', 'visible');}
