I'm trying to make a responsive Navigation Bar Menu in jQuery, but one problem is when you resize the window, click the menu button, then click it again, and then resize the window to full screen, the navigation bar will disappear. I'm not sure how to fix this.
Here is a JSFiddle: https://jsfiddle.net/tqu1edez/ I also posted the code here too.
HTML:
<!DOCTYPE html>
<html>
<head>
<meta name = "viewport" content = "width=device-width, initial-scale=1.0">
<link rel = "stylesheet" type ="text/css" href = "nav.css">
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js">
</script>
</head>
<body>
<nav class = "navigationBar">
<img src = "https://i.imgur.com/nfbKl0W.png" class = "menuIcon">
<ul class = "linkBar">
<li>Home</li>
<li>Contact</li>
<li>About</li>
<li>Media</li>
<li>Miscellaneous</li>
</ul>
</nav>
<script>
$('.menuIcon').on('click', function() {
$('nav ul').fadeToggle('slow');
});
</script>
</body>
</html>
CSS:
#import url('https://fonts.googleapis.com/css?family=Asap');
body
{
background-color: #598392;
margin: 0;
padding: 0;
font-family: 'Asap', sans-serif;
}
.menuIcon
{
display:none;
}
.navigationBar
{
background-color: #124559;
width:100%;
overflow:hidden;
}
.navigationBar li
{
padding:20px;
display: inline;
list-style-type:none;
}
a
{
color: #EFF6E0;
text-decoration: none;
}
a:hover
{
color: #AEC3B0;
}
nav ul
{
padding: 20px;
margin: 0;
}
.show
{
display:block;
transition: fadeIn 2s
}
#media only screen and (max-width: 768px)
{
.menuIcon
{
display:block;
}
.navigationBar li
{
display:block;
padding: 0px;
text-align: center;
}
nav ul
{
display:none;
}
}
Just need to force the nav to show if the screen is large enough
#media only screen and (min-width: 768px)
{
nav ul
{
display: block !important;
}
}

i took this code from w3school where create a responsive nav bar. the nav bar add icon, add functionality for icon and change menu display.
in js code, nav is assign to div element and nav has 2 case, if has class topnav or else (dont have class topnav). in html, nav has class top nav, so i dont understand what else case is for. else case is needed because when i remove else case functionality also change.
please someone explain
body {

overflow: hidden;

</html>
this function is for /* Toggle between adding and removing the "responsive" class to topnav when the user clicks on the icon */
else part is for removing the "responsive" class so that it remain topnav like default it was
nav.className === "topnav" is a exact match statement, so if you click the icon, the nav.className become 'topnav responsive', which is not exact match to 'topnav'(in other words, 'topnav' === 'topnav responsive' is false), this is the functionality that the else block want to handle.
For my webpage (Github Page), I want to make my menu sensible to the size of the screen, such that it collapses when they are too small and the elements do not fit. I am planning to add the following solution: w3schools, using a "burguer" icon to join all the elements when the screens are small.
I am able to create the menu with the different elements, to add the "burguer" icon, and then to hide it by default when the screen is big. However, the media queries and the js function must be wrong, because when I do my screen small, the "burguer" icon appears, but the other elements do not dissapear, and cliking on the "burguer" does nothing. I guess there is a mistakes or confussion with the id names somewhere. Could it be?
In the example from w3schools uses the div tab, but I am not. Is it indispensable for the example to work?
/* Toggle between adding and removing the "responsive" class to topnav when the user clicks on the icon */
function myFunction() {
var x = document.getElementById("nav");
if (x.className === "header_nav") {
x.className += " responsive";
} else {
x.className = "header_nav";
}

The whole code can be found in the repo (Github Repo).
Can you see maybe the error that I am not able to spot? Why the example from w3school is not applicable?
I would really appreciate your help here. Thank you very much in advance!
Here's a small reproducible solution based on your code:
https://jsfiddle.net/hneromu4/5/
I added a class fixed to the link elements that were supposed to stay when we resized the window:
<section id="header_nav">
<nav id="nav">
<ul>
<li class="fixed">Home</li>
<li>Research</li>
<li>Game-dev</li>
<li>Photography</li>
<li class="fixed hamburguer"><i class="fa fa-bars"></i></li>
</ul>
</nav>
</section>
I also tweaked your css and js.
In your CSS and HTML I have made some alterations as your hamburger menu was inside the same thing which you were trying to hide which is not really a good idea I have also adjusted your CSS slightly as you were setting a position to relative but not setting display to block. Hope this helps!
CSS (line 2525 - 2547):
#media screen and (max-width: 600px) {
#nav {display: none;}
#header_nav a.icon {
float: right;
display: block;
}
}
/* The "responsive" class is added to the topnav with JavaScript when the user clicks on the icon. This class makes the topnav look good on small screens (display the links vertically instead of horizontally) */
#media screen and (max-width: 600px) {
#nav.responsive {position: relative;display: block;}
#header_nav.responsive a.icon {
position: absolute;
right: 0;
top: 0;
}
#nav.responsive a {
float: none;
display: block;
text-align: left;
}
}
HTML:
<!-- Header Navigation Menu -->
<section id="header_nav">
<a class="icon" onclick="myFunction()"><i class="fa fa-bars"></i></a><nav id="nav" class="header_nav">
<ul>
<li><p style="color:white">Home</p></li>
<li><p style="color:white">Research</p></li>
<li><p style="color:white">Game-dev</p></li>
<li><p style="color:white">Photography</p></li>

I want to design a fixed height side nav bar , the issue i am facing is when i place the java script code inside html file its work fine but when i place the same code in external JS file it does not work

It looks like your script is missing the file.
It should be for example..
<script src="scripts/abc.js"></script>
I'm trying to create a side bar with 4 different options, when the selected option is active (Meaning you are on that specific page), I want the entire area behind the li, but inside the DIV, a background color slightly darker than what is already there but don't know how to achieve this. I have tried making the li itself 100% width of the div but it doesn't affect it at all.
Here is the issue:
As you can see the li does not reach the start and end width of the sidebar div.

width: 20%;
height: 100%;

#nav li{

padding: 0;
text-align: center;
max-width: 100%;

#nav li a {
display: block;
padding: 0.5em 0;
}
#searchbar{
padding-bottom: 0.5em;
text-align: right;
}
#searchbar input{
max-width: 95%;
}
Your problem is in your #nav. You need to remove the x-margins:
#nav{
margin: 2em 0;
}
You can then do something like this:
#nav li:hover
{
background:#333;
}
But you'll also want to fix this:
#searchbar{
text-align: center;
}
http://jsfiddle.net/5amL4tx5/
Your problem is the #nav rule. If you remove the margins it will fill the entire containing div.
#nav{
margin: 2em 1em;
color: #888888;
display: block;
max-width: 100%;
}
As for changing the background to make it darker for the active element. I suggest creating an .active class and assigning that on the fly to the active page based off of the url.
Example active class:
.active {
background: c2c2c2;
}
I think the problem is here (specifically the 1em for left/right margin):
#nav{
margin: 2em 1em;
}
That's going to limit the size of anything within #nav.
I am designing my website and I'm trying to find a way to keep a header always in the screen.
For an example, take a look at this extra long page on Wikia.com. Notice that when you scroll the page, the little toolbar down the bottom stays in one place. However, scroll to the bottom of the page and you will realize that the toolbar stays in a fixed position until it gets out of view.
This is what I would like to do, but in reverse. Have a header that stays in a fixed position on the web-page, but when it was not in view have it at the top.
I tried looking at an example on DynamicDrive.com (search for Dock Content Script, because I can't post another link), but I found that it was too jittery for me.
Can someone please help me do this?
Thanks in advance.

P.S. Now that I notice, the How to Format box on the right of the submit question page has this effect.
Always remember if you have to stick the header or footer { position : fixed; } can be used.
So apply CSS like this:
.header{
top:0;
width:100%;
height:50px;
position:fixed; // this is the key
}
HTML:
<div id="wrap">
<div id="header"> HEADER </div>
<div id="navigation"> NAVIGATION </div>
<div id="content"> CONTENT </div>
</div>
JavaScript:
( function () {
var nav = $( '#navigation' )[0],
top = $( nav ).offset().top,
left,
height = $( nav ).outerHeight(),
width = $( nav ).width(),
fixedClass = 'fixed';
function pageOffset() {
return window.pageYOffset || document.body.scrollTop;
}
$( window ).
resize( function () {
left = $( nav ).offset().left;
}).
scroll( function () {
$( nav ).toggleClass( fixedClass, pageOffset() > top );
if ( $( nav ).hasClass( fixedClass ) ) {
$( nav ).
css({ 'left': left, 'width': width }).
prev().css({ 'marginBottom': height });
} else {
$( nav ).
prev().andSelf().removeAttr( 'style' );
}
}).
trigger( 'resize' );
})();
Live demo: http://jsfiddle.net/simevidas/Mx8hC/show/
If you want it to be stuck to the top even when the user scrolls (i.e. stuck to the top of the browser window), use:
.top-bar {
position: fixed;
top: 0;
left: 0;
width: 100%;
margin: 0;
}
Or just to the of the the page:
.top-bar {
margin: 0;
width: 100%;
}
You could use CSS positioning to solve this. The following link has instructions on what you need I believe.

Edit: Sorry I misread, these should work for headers as well.
