CSS translation animation doesn't work when parent is shown

There are similar questions like this and this, but don't address this situation.
The goal is to slide a menu onto the screen with CSS translation when its parent is shown. However, showing the parent then applying the CSS class to trigger the translation happens instantly instead of over time. Effectively, there's no animation.
JavaScript could be used to slide the child element onto the screen, but the goal is to keep as much of the animation logic in CSS.
Setting the opacity to 0 doesn't work because we need the menu and its parent to not take any space or be part of the layout.

You can't animate display: none; Set opacity to 0 and then 1 on toggle class. Here's the CodePen for you. ;)
I added a button for the toggle event. Let me know if you need any more help!
enter link description here
$(".btn").on("click", toggleSidebar);
function toggleSidebar() {
$("#sidebar").toggleClass("show");
}
body {
margin: 0;
padding: 0;
}
#sidebar {
opacity: 0;
transition: all 300ms ease-in-out;
}
#sidebar.show {
display: block;
opacity: 1;
}
.overlay {
position: fixed;
width: 100vw;
height: 100vh;
background: red;
z-index: -1;
}
.menuBox {
width: 200px;
height: 100vh;
background: blue;
transition: 300ms ease-in-out;
-webkit-transform: translate(-100%);
}
#sidebar.show .menuBox {
-webkit-transform: translate(0);
}
.btn {
position: absolute;
top: 10px;
left: 20px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="sidebar">
<div class="overlay"></div>
<div class="menuBox"></div>
</div>
<button class="btn">Click</button>

You need to consider an animation. The animation will run automatically when the element appear on the screen
function toggleSidebar() {
$("#sidebar").toggleClass("show");
}
$("#button").on("click", function() {
toggleSidebar();
});
body {
margin: 0;
padding: 0;
}
#button {
position: fixed;
top: 0;
left: 200px;
width: 150px;
height: 50px;
background: yellow;
display: flex;
justify-content: center;
align-items: center;
z-index: 8;
cursor: pointer;
}
#sidebar {
display: none;
}
#sidebar.show {
display: block;
}
.overlay {
position: fixed;
width: 100vw;
height: 100vh;
background: red;
z-index: -1;
}
.menuBox {
width: 200px;
height: 100vh;
background: blue;
transform: translate(-100%);
animation: show 0.3s ease-in-out forwards;
}
#keyframes show {
to {
transform: translate(0);
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="sidebar">
<div class="overlay"></div>
<div class="menuBox"></div>
</div>
<div id="button">CLICK ME</div>
updating display to a value other than none will start all animations applied to the element by the animation-name property, as well as all animations applied to descendants with display other than none. ref

I think you should define the action for your function called. When load page or on click like below:
$(document).ready(function () {
$('#sidebar').on('click', function () {
$(this).toggleClass('show');
});
});

JQuery create expanding div on navigation

Take this snippet:
.container {
width: 150px;
height: 100px;
}
.test {
color: white;
background-color: red;
width: 100%;
height: 25%;
transition: height ease 1s;
}
.test:hover {
height: 100%;
}
<div class="container">
<div class="test">Hover Here</div>
</div>
A simple div inside a container which expands to 100% when hovered over. What I am trying to make is very simular to this, but in a navigation menu (similar to http://www.mineplex.com/).
When a user hovers over the container div (not the main box itself) I need the main div to expand from 0% to 100% in height.
I have tried using JQuery to solve this using a ".hovered" class with no luck. How can one code this?
Any help is much appreciated. Thanks!

Here's a demonstration:
Similarities between both the code snippets:
The containers make use of flex display to make a responsive navbar container, with each of its items spanning a width of 20% (which can be adjusted).
Each of the items (with relative positioning) has two sub containers (with absolute positioning), the first being overlay which we're making use for getting the blue transitioning background(z-index:1) and the second which has a fixed text on the front (z-index:2).
Now, the z-index makes sure that the overlay will be transitioned at the back and text will be fixed in the front, another thing to keep in mind is since we're transitioning it from the bottom up, we set the bottom:0 on the overlay class as well as height:0%;.
On hovering , we transition the height from 0% to 100%.
Differences between both the code snippets:
In the first snippet, we're transitioning each item on hover by making use of .items:hover .overlay.
Whereas in the second snippet, we're transitioning every item when the container is hovered instead of individual items by using .container:hover > *.items> .overlay ( ">" is a direct child selector ).
First: Hovering each item individually to expand the overlay.
.container {
width: 100%;
display: flex;
height: 80px;
background: gray;
justify-content: center;
align-items: center;
}
.items {
flex: 0 1 20%;
height: 100%;
margin-right: 5px;
position: relative;
overflow: hidden;
}
.overlay {
position: absolute;
background: blue;
z-index: 1;
width: 100%;
height: 0%;
bottom: 0;
transition: all 0.5s ease-in-out;
}
.item-text {
position: absolute;
text-align: center;
color: white;
z-index: 2;
width: 100%;
height: 100%;
top: 0;
}
.items:hover .overlay {
height: 100%;
}
<div class="container">
<div class="items">
<div class="overlay"></div>
<div class="item-text">Home</div>
</div>
<div class="items">
<div class="overlay"></div>
<div class="item-text">About</div>
</div>
<div class="items">
<div class="overlay"></div>
<div class="item-text">Contact</div>
</div>
<div class="items">
<div class="overlay"></div>
<div class="item-text">Other</div>
</div>
</div>
Second: When the user hovers over the container, expanding all the overlays.
.container {
width: 100%;
display: flex;
height: 80px;
background: gray;
justify-content: center;
align-items: center;
}
.items {
flex: 0 1 20%;
height: 100%;
margin-right: 5px;
position: relative;
overflow: hidden;
}
.overlay {
position: absolute;
background: blue;
z-index: 1;
width: 100%;
height: 0%;
bottom: 0;
transition: all 0.5s ease-in-out;
}
.item-text {
position: absolute;
text-align: center;
color: white;
z-index: 2;
width: 100%;
height: 100%;
top: 0;
}
.container:hover > *.items> .overlay {
height: 100%;
}
<div class="container">
<div class="items">
<div class="overlay"></div>
<div class="item-text">Home</div>
</div>
<div class="items">

Cut/Rearange background centered instead of resizing

I have a little test site, where the width of a div gets decreased to 50% and another div appears when we click on button.
Here is my codepen
When you click on the button, the image just gets resized.
Because I am using: background-size: 100%;
But I want the image to move a bit to the left, so that it gets centred.

There's one simple thing you can do:
Just remove the bg image from content-container div and add it to the body
body{
background: url("http://foto-muehlbacher.at/wp-content/uploads/2014/01/Landschaft33-1.jpg");
}
Here's a working example:
$('#button').click(function(){
$('.new-content').toggleClass('half').delay(0).fadeIn(200);
$('.content-container').toggleClass('half').style.width = "50%".backgroundSize = "200%";
});
.content {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
text-align: center;
width: 100%;
}
body{
background: url("http://foto-muehlbacher.at/wp-content/uploads/2014/01/Landschaft33-1.jpg");
}
.content-container {
height: 100vh;
display: block;
background-size: 100%;
float: left;
width: 100%;
position: relative;
transition: .2s ease-in-out;
}
.new-content {
display: none;
overflow: auto;
float: right;
width: 0;
height: 100vh;
background: #f60;
transition: .2s ease-in-out;
}
.new-content.half,
.content-container.half {
width: 50%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="content-container">
<div class="content">
<div>text</div>

Css transform animation from right to left

I am working with a navigation bar that has slides a menu from right to left.
With my code, when the user picture is being clicked, it will show the menu.
So when it is loaded, menu is hidden and when it is clicked will be showed. I used to add class hidden and show to toggle to menu.
$(document).ready(function(){
$(".img-profile").click(function(){
$(".menu-wrapper").addClass("show");
});
$(".menu-bg").click(function(){
$(".menu-wrapper").removeClass("show");
});
});
CSS
.show{
display: inline-block !important;
}
.hidden{
display: none;
}
The problem is it's not animating even if I added the transition: all 0.2s linear 0s and the transform from 250px to 0
.menu-wrapper > .login-menu{
background-color: #fff;
height: 100%;
overflow-y: auto;
position: fixed;
right: 0;
width: 250px;
z-index: 5;
padding: 30px 20px;
text-align: center;
transition: all 0.2s linear 0s;
transform: translateX(0px);
}
.menu-wrapper .show > .login-menu{
transform: translateX(250px);
}
Also, I want to animate it on menu-close from right to left.
My full code is at JSFIDDLE

Changing the display CSS attribute does not trigger animations. Use the visibility attribute instead. This one triggers animations.
If you have good reason to use display (which is completely possible), you'll need to set the display attribute first to show the element, but keep the visibility on hidden. Set the visibility: visible attribute right after and the animation will be triggered.
Edit: I had a look at your fiddle. Don't use the .hidden class, because bootstrap sets display:none on .hidden elements. Just use the .show class alone, putting visibility:visible in the show class, and setting visibility:hidden on the .menu-wrapper element. Remove all the display:none lines in your CSS and you'll be fine.

Try to do it with this trick.

this is working for me
$(".myButton").click(function () {
// Set the effect type
var effect = 'slide';
// Set the options for the effect type chosen
var options = { direction: $('.mySelect').val() };
// Set the duration (default: 400 milliseconds)
var duration = 500;
$('#myDiv').toggle(effect, options, duration);
});

making a toggle button to change panels

I have two panels at the top of my application and one button at the button. By default only panel one must be visible, but by clicking on the button panel one fades away, and panel two fades in. I created the layout, but I do not know how to achieve it.

First of all since I did $('.panel2').hide();, in page load first it loads the panel then hides it. How can I make it invisible from the beginning?
Secondly how can I make the panel2 visible only by pressing the button?
And finally is there anyway to add some transitions effects for changing panels?

You may try:
$(".grid-button").on("click", function() {
var visibleObj = $('.mainSection div:visible');
var inVisibleObj = $('.mainSection div:hidden');
visibleObj.fadeOut(500, function() {
inVisibleObj.fadeIn(500);
});
});
While for the visibility you need:
<div class="panel2" style="display: none;">Panel2</div&gt
The running snippet:
$(function () {
$(".grid-button").on("click", function() {
var visibleObj = $('.mainSection div:visible');
var inVisibleObj = $('.mainSection div:hidden');
visibleObj.fadeOut(500, function() {
inVisibleObj.fadeIn(500);
});
});

To make one of the panels hidden in the first place, I'd use a css class called hidden:
.hidden{
display : none;
}
Which simply makes what it sounds like, hiding the element.
Than, I'd set this class in the HTML decleration:
<div class="panel2 hidden">Panel2</div>
That will hide panel2 on page load, and by that you don't have to hide it using js code.
Than, I'd use a helper css class called panel that stands to be a panel identifier (you can either use the data attribute, or any other way of identifying those elements).
For 5 panels, it would look like this:
<div class="panel panel1">Panel1</div>
<div class="panel panel2 hidden">Panel2</div>
<div class="panel panel3 hidden">Panel3</div>
<div class="panel panel4 hidden">Panel4</div>
<div class="panel panel5 hidden">Pane5</div>
At last, to make this work for any number of panels you want (not necesseraly 2), I'd use a "carousel" effect to toggle the panels visibility, while having a way to keep track with them (adding and removing the hidden class), and use the fadeIn/fadeOut effect. (again, instead of identifying the panels using the panel1,panel2,panel3... classes, you can always use the data attribute (please read more about it in jQuery docs), or in any other way).
var currentPanel = 1;
$(".grid-button").on("click", function() {
$(".grid").toggleClass("open close");
$(".panel"+currentPanel).fadeOut("normal", function(){
$(this).addClass('hidden');
});
currentPanel = currentPanel >= $(".panel").length ? 1 : currentPanel+1;
$(".panel"+currentPanel).fadeIn().removeClass('hidden');
});
Just note that the hidden class actually "looses" it's functionality after the first click, since jQuery changes the display property inline, but I think that it might not be harmful to keep them anyway (it will be easier to track them).
