Why doesn't my nav bar hide when scrolling down and appear when scrolling up?

So I've tried adapting this http://jsfiddle.net/mariusc23/s6mLJ/31/ code to my webpage so that my nav bar hides when scrolling down and appears when scrolling back up, however it doesn't seem to work and I just can't see the problem, I've included my code below, thanks for the help!
<script>
// Hide Header on on scroll down
var didScroll;
var lastScrollTop = 0;
var delta = 5;
var navbarHeight = $('header').outerHeight();
$(window).scroll(function(event){
didScroll = true;
});
setInterval(function() {
if (didScroll) {
hasScrolled();
didScroll = false;
}
}, 250);
function hasScrolled() {
var st = $(this).scrollTop();
// Make sure they scroll more than delta
if(Math.abs(lastScrollTop - st) <= delta)
return;
// If they scrolled down and are past the navbar, add class .nav-up.
// This is necessary so you never see what is "behind" the navbar.
if (st > lastScrollTop && st > navbarHeight){
// Scroll Down
$('header').removeClass('nav-down').addClass('nav-up');
} else {
// Scroll Up
if(st + $(window).height() < $(document).height()) {
$('header').removeClass('nav-up').addClass('nav-down');
}
}
lastScrollTop = st;
}

<h1>Titanic Movie Review 1996</h1>

<p>
The Titanic is a classic movie filmed in 1996, with jack and rose, it is a classic tradgedy and feautures kate and leonardo da vinci, one is poor, one is rich, the girl has a expensive random amulet that look quite cool i think, yeah, and then the ships crashes and they all die! except for rose. And heres a random movie review from somewhere:<br><br>
Like a great iron Sphinx on the ocean floor, the Titanic faces still toward the West, interrupted forever on its only voyage. We see it in the opening shots of “Titanic,” encrusted with the silt of 85 years; a remote-controlled TV camera snakes its way inside, down corridors and through doorways, showing us staterooms built for millionaires and inherited by crustaceans.<br><br>
These shots strike precisely the right note; the ship calls from its grave for its story to be told, and if the story is made of showbiz and hype, smoke and mirrors--well, so was the Titanic. She was “the largest moving work of man in all history,” a character boasts, neatly dismissing the Pyramids and the Great Wall. There is a shot of her, early in the film, sweeping majestically beneath the camera from bow to stern, nearly 900 feet long and “unsinkable,” it was claimed, until an iceberg made an irrefutable reply.<br><br>
James Cameron's 194-minute, $200 million film of the tragic voyage is in the tradition of the great Hollywood epics. It is flawlessly crafted, intelligently constructed, strongly acted and spellbinding. If its story stays well within the traditional formulas for such pictures, well, you don't choose the most expensive film ever made as your opportunity to reinvent the wheel.<br><br>
We know before the movie begins that certain things must happen. We must see the Titanic sail and sink, and be convinced we are looking at a real ship. There must be a human story--probably a romance--involving a few of the passengers. There must be vignettes involving some of the rest and a subplot involving the arrogance and pride of the ship's builders--and perhaps also their courage and dignity. And there must be a reenactment of the ship's terrible death throes; it took two and a half hours to sink, so that everyone aboard had time to know what was happening, and to consider their actions.<br><br>
All of those elements are present in Cameron's “Titanic,” weighted and balanced like ballast, so that the film always seems in proportion. The ship was made out of models (large and small), visual effects and computer animation. You know intellectually that you're not looking at a real ocean liner--but the illusion is convincing and seamless. The special effects don't call inappropriate attention to themselves but get the job done.<br><br>
The human story involves an 17-year-old woman named Rose DeWitt Bukater (Kate Winslet) who is sailing to what she sees as her own personal doom: She has been forced by her penniless mother to become engaged to marry a rich, supercilious snob named Cal Hockley (Billy Zane), and so bitterly does she hate this prospect that she tries to kill herself by jumping from the ship. She is saved by Jack Dawson (Leonardo DiCaprio), a brash kid from steerage, and of course they will fall in love during the brief time left to them.<br><br>
The screenplay tells their story in a way that unobtrusively shows off the ship. Jack is invited to join Rose's party at dinner in the first class dining room, and later, fleeing from Cal's manservant, Lovejoy (David Warner), they find themselves first in the awesome engine room, with pistons as tall as churches, and then at a rousing Irish dance in the crowded steerage. (At one point Rose gives Lovejoy the finger; did young ladies do that in 1912?) Their exploration is intercut with scenes from the command deck, where the captain (Bernard Hill) consults with Andrews (Victor Garber), the ship's designer and Ismay (Jonathan Hyde), the White Star Line's managing director.<br><br>

I'm currently trying to make a movie review blog post and really want to make everything just stand out, but I'm only relatively new to Css,html and javascript therefore I really can't identify any problems I might have and how to fix them. Again thank you for y'alls help :)

its because you have additional closing tag on line no 15 and 98 in your html, I have fixed that see below demo
var didScroll;
var lastScrollTop = 0;
var delta = 5;
var navbarHeight = $('header').outerHeight();
$(window).scroll(function(event){
didScroll = true;
});
setInterval(function() {
if (didScroll) {
hasScrolled();
didScroll = false;
}
}, 250);
function hasScrolled() {
var st = $(this).scrollTop();
// Make sure they scroll more than delta
if(Math.abs(lastScrollTop - st) <= delta)
return;
// If they scrolled down and are past the navbar, add class .nav-up.
// This is necessary so you never see what is "behind" the navbar.
if (st > lastScrollTop && st > navbarHeight){
// Scroll Down
$('header').removeClass('nav-down').addClass('nav-up');
} else {
// Scroll Up
if(st + $(window).height() < $(document).height()) {
$('header').removeClass('nav-up').addClass('nav-down');
}

URL structure for tabs issue

As I have issue with URL Structure within the tabs. if I have selected the tab-2 and the url is changed to https://example.com/#tab-2 and for tab-3 https://example.com/#tab-3 and so on.
The issue is if I have entered in this https://example.com/#tab-4 or any other, in search bar, it always shows me https://example.com/#tab-1 as current.
But, I would like to do https://example.com/#tab-4 the current shows me tab-4 selected. How would I implement in my current code?
$('.projects_select').click(function(){
var tab_id = $(this).attr('data-tab');
$('.projects_select').removeClass('current');
$('.tab-content').removeClass('current');
$(this).addClass('current');
$("#"+tab_id).addClass('current');
// window.location.href = window.location.href+"#tab_id";
});
.tab-content {
display: block; /* undo display:none */
height: 0; /* height:0 is also invisible */
overflow: hidden; }
.tab-content.current {
height: auto; /* let the content decide it */ }
.projects_select {
font-weight: 400;
letter-spacing: 1px;
text-align: center;
color: #333;
padding: 17px 0;
width: 16.66%;
float: left;
cursor: pointer;
border-style: solid;
border-width: 1px 1px 1px 0px;
font-style: normal;
font-weight: 700; }
.projects_select.current {
font-weight: 500;
position: relative;
color: #fff;
background: #313641; }
.projects_select.current:after {
top: 100%;
left: 50%;
border: solid transparent;
content: " ";
height: 0;
width: 0;
position: absolute;
pointer-events: none;
border-color: transparent;
border-top-color: #333;
border-width: 20px;
margin-left: -20px;
}
.tab_Menu{
padding: 35px 10.7% 75px;
background: #efefef; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="wrapper tab_Menu">
<a class="projects_select tab-link current" data-tab="tab-1" href="#tab-1"> Tab-1 </a>
<a class="projects_select tab-link" data-tab="tab-2" href="#tab-2"> Tab-2 </a>
<a class="projects_select tab-link" data-tab="tab-3" href="#tab-3"> Tab-3 </a>
<a class="projects_select tab-link" data-tab="tab-4" href="#tab-4"> Tab-4 </a>
<a class="projects_select tab-link" data-tab="tab-5" href="#tab-5"> Tab-5 </a>
</div>
<div class="tab-content current" id="tab-1"> Tab-1 </div>
<div class="tab-content" id="tab-2"> Tab-2 </div>
<div class="tab-content" id="tab-3"> Tab-3 </div>
<div class="tab-content" id="tab-4"> Tab-4 </div>
<div class="tab-content" id="tab-5"> Tab-5 </div>

You can get the hash with window.location.hash. So in your script you can do something like this:
$(document).ready(function(){
if($('.tab-link[href=' + window.location.hash + ']')){
$('.tab-link[href=' + window.location.hash + ']').addClass('current');
}
else {
$('.tab-link[href=#tab1]').addClass('current');
}
});
Not tested this code tho. You don't need to set current class in HTML anymore. You can remove it there.

How to increase the width of my twitter feed

I am trying to increase the width of the twitter feed displayed on my webpage, I added a Div id to it and tried increasing its size in css however it stops getting bigger after a certain point, Also I want to add images in my portfolio section which includes 3 random pictures of like computers which get bigger and change size when you hover over them in css, how do I do this? Also I can't figure out how to change the color of the background of the webpage, everything I have tried doesn't work. Thanks.
I have provided the HTML, CSS and JS code for my code below.

Your Twitter feed has a width set in HTML property. Erase the property and move it to CSS. That should fix the Twitter thing. Edit: Remember that the height is set on Twitter > Settings > Widget > Height.
- EDIT 1 -
Now that I know your Twitter feed can't be controlled by you, you have to control the result of your Twitter script which will normally be 600px of height by default. No matter what this is, you know it will end up styling an iframe with the twitter-timeline CSS class, so you only need to overwrite the value like this:
.twitter-timeline {
height: 503px; // 503 because for some reason it needs 3 more pixels to catch up with your video, as I could see.
}
- END EDIT 1 -
You just gave away all of your personal information to strangers around the web. You'll probably be spammed in a few seconds if they are true. I suggest you ONLY provide necessary code. There is a lot of CSS and HTML not related to the question, you can simply ask them in another question or explain them apart of each other.
To place pictures you can do many things, being them random means either JavaScript or preloaded with PHP. I imagine you would be loading them from your site, let's say /images/computers/ and give them a class, for instance photo. Then on CSS, you can do the following:
.photo {
height:200px;
}
.photo:hover {
height:400px;
}
That will make it bigger on hover using CSS. If you like to animate it, you might want to use other CSS properties. Search on the web, you'll find them.
- EDIT 2 -
So, looking at your pictures with the class photo, I see that you were not adding the % values correctly. You need to find a balanced value for each one of your images. In your case, we are playing with image padding, margin and width basically. So there are 3 images and you know that the percentage must reach something around 100%:
.photo {
background-color: white;
padding: 1%;
margin-left: 5%;
margin-bottom: 2%;
-webkit-box-shadow: 0 0 0.2em 0.15em rgba(00, 00, 00, 0.35);
box-shadow: 0 0 0.2em 0.15em rgba(00, 00, 00, 0.35);
float: left;
width: 25%;
transition: all 0.25s ease-out;
}
According to this code I wrote for you, now the formula is:
(3 * 25%) + (6 * 1%) + (3 * 5%) = 75% + 6% + 15% = 96%
6 times 1% because the padding will be added to both left and right of the picture.
- END EDIT 2 -
The background color of the website? That is just too basic. It depends on your needs, you can set your background color to the <html> or <body>. I'll use HTML:
html {
background-color:red;
}
With that, your website will have a red background. Of course you can use HEX, or rgb() or rgba() or color names, whatever you want.

Try this codes.
twitter frame having max-width="520" that is a boundary.portfolia images supported responsive also.
MAKE IT COOL,WE LOVE OUR CODING.

Why are my links at different heights?

I have a page that includes links, in the form of inline-blocks, to a couple of pages. My links stay at the same height, as long as they have identical text. Like this: Screenshot of webpage
However, when I change the text in the boxes, whichever box has fewer characters is lower than the other. Like this: Screenshot of webpage
Can anyone tell me why this is happening and how to fix it?
Here is my HTML, CSS, and JavaScript:
//The JavaScript is probably irrrelevant, but maybe not
//Set menu block height proportionally to the width
var menuAWidth = $('.menu a').css('width');
menuAWidth = menuAWidth.substring(0, menuAWidth.length - 2);
var menuAHeight = menuAWidth*1.618;
menuAHeight = (Math.round(menuAHeight*1000))/1000;
$('.menu a').css('height', menuAHeight);
//Reset height of menu block on resize
$(window).resize(function() {
var menuAWidth = $('.menu a').css('width');
menuAWidth = menuAWidth.substring(0, menuAWidth.length - 2);
var menuAHeight = menuAWidth*1.618;
menuAHeight = (Math.round(menuAHeight*1000))/1000;
$('.menu a').css('height', menuAHeight);
});

display: inline-block causes this behaviour. There's a decent amount of info about this here: http://designshack.net/articles/css/whats-the-deal-with-display-inline-block/
Short answer: use vertical-align: top on your inline-block elements to keep the tops aligned (rather than sticking to the baseline default), or try floats instead.

JavaScript Enabled Scroll Fixed Nav Bar Trouble

I have a JavaScript enabled scrolling nav bar. It starts below a hero graphic then sticks to the top when it gets to the top. It works perfectly, however, when it reaches the top it causes the div below it to snap to the top instead of smoothly getting there. It's hard to explain so here's the code.
I know what's happening: Once the nav bar reaches the top, it stacks above the div causing the div to "jump." I just can't figure out how to make it smoother.
Here's the code and thanks for your thoughts!

var win = $(window),
fxel = $(".header"),
eloffset = fxel.offset().top;
win.scroll(function() {
if (eloffset < win.scrollTop()) {
fxel.addClass("fixed");
} else {
fxel.removeClass("fixed");
}
});
</script>

When a div is fixed, it will no longer take up "space", meaning the next div will do exactly as you described -- stack up near the top.
Consider wrapping all of your content after the header using a div:
<div class="header">
...
</div>
<div class="main-body">
<div class="intro">
<p class="maintext">
We are dedicated to delivering the latest information on current threats, to provide industry best practices, and to enhance every public sector IT professional's understanding of cybersecurity by opening direct conversations between the government and IT community.
</p>
</div>
</div>
When we fix the header, we can add top-padding equal to the height of the header to the main-body div to prevent it from jumping.
var win = $(window),
fxel = $(".header"),
eloffset = fxel.offset().top;
win.scroll(function() {
if (eloffset < win.scrollTop()) {
$(".main-body").css("padding-top", fxel.height());
fxel.addClass("fixed");
} else {
$(".main-body").css("padding-top", 0);
fxel.removeClass("fixed");
}
});
