Try to reset the animation, also avoid too many parent() call as possible by select closest element or create better class names.
So here I make a small modification to get what you need, by add a class name to the background img that trigger animation, every time you change the hover to other menu item (LI element) it will toggle the class name so the animation will restart each time.
$(function () {
var image = $('.menu').find('img').attr('src');
var lastImage
$('.menu ul li.navLink').mouseover(function () {
var currentImage = $(this).attr('data-img');
$('.navigationGif img').attr('src', currentImage);
if(lastImage !== currentImage) {
$('.navigationGif').removeClass('animation')
setTimeout(() => {
$('.navigationGif').addClass('animation')
}, 10);
lastImage = currentImage
}
})
});

How can I get the FadeInLeft effect when changing content from .opacity=0 to .opacity=1 on the left side.
I tried to solve this problem with the given script, but it did not work for me.
P.S. See this layout in fullscreen.

Here is a very ruff first draft
Since you already have the .active class being added to your .subtitle class to change opacity, you can just tack on CSS Animation to those classes.
In my example I have .subtitle > div set to right: 100%; and .active > div set to right: 0%; with a transition: 300ms;
Which will animate the block from the left side of the screen over to the right side in 300ms. You can play around with this until you get the animation where you'd like.
Here's a great article from MDN with more information about Using CSS Transitions
CSS transitions provide a way to control animation speed when changing CSS properties. Instead of having property changes take effect immediately, you can cause the changes in a property to take place over a period of time. For example, if you change the color of an element from white to black, usually the change is instantaneous. With CSS transitions enabled, changes occur at time intervals that follow an acceleration curve, all of which can be customized.
Examples
div {
transition: <property> <duration> <timing-function> <delay>;
}
#delay {
font-size: 14px;
transition-property: font-size;
transition-duration: 4s;
transition-delay: 2s;
}
#delay:hover {
font-size: 36px;
}
.box {
border-style: solid;
border-width: 1px;
display: block;
width: 100px;
height: 100px;
background-color: #0000FF;
transition: width 2s, height 2s, background-color 2s, transform 2s;
}
.box:hover {
background-color: #FFCCCC;
width: 200px;
height: 200px;
transform: rotate(180deg);
}

Javascript eventListener only working in some areas of the element

So i was building a burger menu responsive navbar. I finished up most of the working but i got stuck at one point. The problem is i have applied the javascript onClick event listener on the div .burger so that it changes the opacity of the .nav-container to 1. Up until to this point this works fine. The problem is this click event only works in some areas on the .burger. Like if clicked on of the lines in it or somewhere to the right. I can't seem to find the problem. Can someone help me with this? Thanks in advance.
Here is my code
function showNav() {
var nav = document.getElementById("nav");
nav.classList.add("show-nav");
}
* {
margin: 0px;
padding: 0;
box-sizing: border;
}
.container {
display: flex;
margin-top: 2%;
}
header {
position: relative;
z-index: 1;
}
.line1,
.line2,
.line3 {
width: 40px;
height: 8px;
background-color: black;
margin-top: 3px;
}
.nav-heading {
flex: 4;
margin-left: 5%;
}
.burger {
flex: 1;
margin-left: 40%;
background-color: red;
padding: 0;
width: auto;
}
.nav-container {
position: absolute;
width: 100%;
opacity: 0;
transition: .2s ease-in-out;
transform: translateY(-20%);
transform-origin: left;
ul {
display: flex;
flex-direction: column;
background-color: blue;
width: 100%;
align-items: center;
list-style-type: none;
li {
flex: 1;
padding: 15px;
}
}
}
.show-nav {
opacity: 1;
transform: translateY(20%);
}
<header>
<div class="container">
<div class="nav-heading">
<h1>Navbar</h1>
</div>
<div class="burger" onclick="showNav()">
<div class="line1"></div>
<div class="line2"></div>
<div class="line3"></div>
</div>
</div>
<div class="nav-container" id="nav">
<ul>
<li>Home</li>
<li>About</li>
<li>Contact</li>
</ul>
</div>
</header>

Just put z-index = 1 on .burger.
.burger {
flex: 1;
margin-left: 40%;
background-color: red;
padding: 0;
width: auto;
z-index: 1;
}

to bring your menu up front , you can add position:relative + z-index:1; to make sure it stands on top.
You also add the rule cursor: pointer; to show it is a clickable element :)
For the class you add, you could use classList . toggle() , so it shows/hides alternatively.
example
function showNav() {
var nav = document.getElementById("nav");
nav.classList.toggle("show-nav");
}
* {
margin: 0px;
padding: 0;
box-sizing: border;
}
.container {
display: flex;
margin-top: 2%;
}
header {
position: relative;
z-index: 1;
}
.line1,
.line2,
.line3 {
width: 40px;
height: 8px;
background-color: black;
margin-top: 3px;
}
.nav-heading {
flex: 4;
margin-left: 5%;
}
.burger {
flex: 1;
margin-left: 40%;
background-color: red;
padding: 0;
width: auto;
cursor: pointer;
position:relative;
z-index:1
}
.nav-container {
position: absolute;
width: 100%;
opacity: 0;
transition: .2s ease-in-out;
transform: translateY(-20%);
transform-origin: left;
}
ul {
display: flex;
flex-direction: column;
background-color: blue;
width: 100%;
align-items: center;
list-style-type: none;
}
li {
flex: 1;
padding: 15px;
}
li a {
color: black;
}
.show-nav {
opacity: 1;
transform: translateY(20%);
}
<header>
<div class="container">
<div class="nav-heading">
<h1>Navbar</h1>
</div>
<div class="burger" onclick="showNav()">
<div class="line1"></div>
<div class="line2"></div>
<div class="line3"></div>
</div>
</div>
<div class="nav-container" id="nav">
<ul>
<li>Home</li>
<li>About</li>
<li>Contact</li>
</ul>
</div>
</header>

Just change the width of
.nav-container {
width: 30%;
}
so it doesn't overlap the burger. In general your CSS structure is not good.

});

$('.gallery').on('click', function(event){
event.preventDefault();

});
});
The problem I am having is that if a category is more than 2 words, it doesn't show the projects with that category. You'll see in the code pen that there is a category called "Testing Testing Testing" and one of the projects has that category assigned to it. But, when you click the Testing Testing Testing category, no projects show up. All of the other categories work however, because they are all only 2 words long.
Any help is greatly appreciated!

Your code break because the .replace(' ', '-') code just replace the first space
if you want to change all space with '-', you should change this code
var category = $(this).text().toLowerCase().replace(' ', '-');
to this
var category = $(this).text().toLowerCase().split(' ').join('-');

Click back arrow not working properly in JavaScript

This is my html and JavaScript code I want help in this task, After I go back and forth into the submenus several times, the padding gets messed up for the elements and the icons get cut off.
Some times it work properly but when I click back arrow very quickly Its messed the paddings.
I am sharing screenshot also.
$(document).ready(function() {
// Variable declaration...
var left, width, newLeft;
// Add the "top-menu" class to the top level ul...
$('.mobile-menu').children('ul').addClass('top-menu');
// Add buttons to items that have submenus...
$('.has_child_menu').append('<button class="arrow"><i class="fa fa-chevron-right"></i></button>');
// Mobile menu toggle functionality
$('.menu-toggle').on('click', function() {
// Detect whether the mobile menu is being displayed...
display = $('.mobile-menu').css("display");
if (display === 'none') {
// Display the menu...
$('.mobile-menu').css("display", "block");
} else {
// Hide the mobile menu...
$('.mobile-menu').css("display", "none");
// and reset the mobile menu...
$('.current-menu').removeClass('current-menu');
$('.top-menu').css("left", "0");
$('.back-button').css("display", "none");
}
});
// Functionality to reveal the submenus...
$('.arrow').on('click', function() {
// The .current-menu will no longer be current, so remove that class...
$('.current-menu').removeClass('current-menu');
// Turn on the display property of the child menu
$(this).siblings('ul').css("display", "block").addClass('current-menu');
left = parseFloat($('.top-menu').css("left"));
width = Math.round($('.mobile').width());
newLeft = left - width;
// Slide the new menu leftwards (into the .mobile viewport)...
$('.top-menu').css("left", newLeft);
// Also display the "back button" (if it is hidden)...
if ($('.back-button').css("display") === "none") {
$('.back-button').css("display", "flex");
}
});
// Functionality to return to parent menus...
$('.back-button').on('click', function() {
// Hide the back button (if the current menu is the top menu)...
if ($('.current-menu').parent().parent().hasClass('top-menu')) {
$('.back-button').css("display", "none");
}
left = parseFloat($('.top-menu').css("left"));
width = Math.round($('.mobile').width());
newLeft = left + width;
// Slide the new menu leftwards (into the .mobile viewport)...
$('.top-menu').css("left", newLeft);
// Allow 0.25 seconds for the css transition to finish...
window.setTimeout(function() {
// Hide the out-going .current-menu...

<h1>Mobile menu demo</h1>
<p>Click the button above to see the mobile menu in action!</p>
<p>The menu functionality was inspired by the Settings app in iOS.</p>
<p>This implementation uses some jQuery and flexbox. The orginal code was written for a WordPress theme, so absolute positioning was used (rather than fixed positioning - which is easier) to avoid conflicts with the admin bar (when the user is logged-in).</p>

Do transition: 0.15s; instead of transition: 0.25s; in css file.

JQuery - Add/Remove class on vertical scroll has no effect

I am trying to add and remove a class based on vertical scroll (to the navbar) but there seems to be no effect.
I want the navbar to change background color on scroll and I cant understand why it has not effect.
I have tried adding just css using $(element).css but that doesnt seem to be making a difference either

Checks if offset is > 50 and then should add css (color:black)
JQuery:
$(document).ready(function() {
$(window).scroll(function() {
var scroll_offset = $(window).scrollTop;
if (scroll_offset > 50) {
$(".nav").css("color", "black");
}
});
});

var scroll_offset = $(window).scrollTop();
$.fn.scrollTop is a function. You forgot to invoke it.

Also can try this:
$(window).scroll(function() {
if ($(window).scrollTop() >= 50) {
$(".nav ul li a").css("color", "black");
} else {
$(".nav ul li a").css("color", "white");
}
});
JSFiddle

Invoke the scrollTop function (scrollTop())
Fix the selector: nav a instead of .nav
Add else statement to restore original color
jsFiddle demo
$(document).ready(function() {
$(window).scroll(function() {
var scroll_offset = $(window).scrollTop();
//alert(scroll_offset);
if (scroll_offset > 50) {
$("nav a").css("color", "black");
} else {
$("nav a").css("color", "white");
}
