I am attempting to get a panel to slide up when a trigger is selected. This is working in my snippet. The issue is that the contents within the #proposal-panel are showing, even though I have #proposal-panel set to opacity: 0, until the trigger is clicked (.active is added). It is showing at the bottom of the page.
Also, for some reason on my actual site, the panel is not sliding up. I have multiple sections, just like the example. The panel just sets at the bottom of the page. The only thing that happens when the active class is added is the z-index takes effect.
I am wanting the panel to slide from the bottom to the top when triggered. That is what I am trying to do with translateYin the active class.
Does anyone know why the contents are showing and possibly why the panel is not sliding up?
Here is a fiddle.
$('#proposal-trigger').on('click', function () {
$('#proposal-panel').addClass('active');
});
#red {
height: 100vh;
width: 100%;
background: red;
}
#blue {
height: 100vh;

}
#proposal-trigger {
background: #3B3B3B;

Assuming it's the little black box you see at the bottom, that's from #proposal-trigger. #proposal-panel is hidden. I removed the background color from #proposal-trigger to get rid of that.
And to have the element slide up, use transform: translate().
$('#proposal-trigger').on('click', function() {
$('#proposal-panel').addClass('active');
});
#red {
height: 100vh;
width: 100%;
background: red;
}
#blue {
height: 100vh;
width: 100%;
background: blue;
}
#proposal-trigger {
width: 100px;
height: 100px;
position: fixed;
bottom: 0;
right: 200px;
}
#proposal-panel {
background: #333333;
width: 58%;
height: 100vh;
position: fixed;
padding: 15px 0;
right: 0;
opacity: 0;
transition: 0.3s;
transform: translateY(100%);
bottom: 0;
}
#proposal-panel.active {
transform: translateY(0);
z-index: 99;
opacity: 1;
}

<div id="proposal-panel"></div>
You don't need to use translateY to do this animations, just need to use top and bottom with the fixed position. And remove the background-color from #proposal-trigger so it doesn't show anymore
Here is a demo
$('#proposal-trigger').on('click', function () {
$('#proposal-panel').addClass('active');
});
<section id="red"></section>
<section id="blue"></section>
<div id="proposal-trigger">
<input>

<div id="proposal-panel"></div>

width: 100%;
background: blue;
}
#proposal-trigger {
width: 100px;
height: 100px;
position: fixed;
bottom: 0;
right: 200px;
}
#proposal-panel {
background: #333333;
width: 58%;
position: fixed;
padding: 15px 0;
right: 0;
bottom: 0;
top: 100%;
opacity: 0;

}
#proposal-panel.active {

Here is a codepen: https://codepen.io/jon424/pen/XWzGNLe
In this example, if you select the toggle button, the image will be covered by another div. The white square will gradually cover the image from the top of the image to the bottom.
I simply want to reverse this effect. I want the white square to cover the image, moving from the bottom of the image to the top.
I’ve tried using a negative value for max-height in the .covered class, but that wasn’t working. Any idea on how I can go about doing this?
document.querySelector('.child2').classList.add('covered');
document.querySelector('button').addEventListener('click', () => {
document.querySelector('.child2').classList.toggle('covered');
});
.parent {
position: relative;
width: 300px;
height: 300px;
margin: 10px;
overflow: hidden;
}
.child1 {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
}
.child2 {
z-index: 1;
background: #ffffff;
transition: max-height 1s ease-in-out;
max-height:100%;
}
.covered {
max-height: 0px;
}
<button>Toggle</button>
<div class="parent">
<img class="child1" src="https://picsum.photos/200/300">
<div class="child1 child2"></div>
</div>
Very simple: change the top: 0; attribute in .child1 to bottom: 0;
Here is another way to do it you can manipulate the top of the child2:
document.querySelector('button').addEventListener('click', () => { document.querySelector('.child2').classList.toggle('covered');});
.parent {
position: relative;
width: 300px;
height: 300px;
margin: 10px;
overflow: hidden;
}
.child1 {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
}
.child2 {
position: absolute;
top: 100%;
z-index: 1;
background: #ffffff;
transition: top 1s ease-in-out;
max-height: 100%;
}
.covered {
top: 0px;
}
<button>Toggle</button>
<div class="parent">
<img class="child1" src="https://picsum.photos/200/300">
<div class="child1 child2"></div>
</div>
By adding those lines on .child2 I am getting I think what you want:
bottom:0;
top:unset;
Here is the full working example:
document.querySelector(".child2").classList.add("covered");
document.querySelector("button").addEventListener("click", () => {
document.querySelector(".child2").classList.toggle("covered");
});
.parent {
position: relative;
width: 300px;
height: 300px;
margin: 10px;
overflow: hidden;
}
.child1 {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
}
.child2 {
z-index: 1;
background: #ffffff;
transition: max-height 1s ease-in-out;
max-height: 100%;
bottom:0;
top:unset;
}
.covered {
max-height: 0px;
}
<button>Toggle</button>
<div class="parent">
<img class="child1" src="https://picsum.photos/200/300">
<div class="child1 child2"></div>
</div>
Not sure but are you looking for this type of effect, I know CSS solution if this help you.
.parent {
position: relative;
}
.parent::before {
content: "";
position: absolute;
height: 0;
width: 100%;
background-color: white;
bottom: 100%;
left: 0;
transition: all 0.9s ease-in-out;
}
.parent:hover::before {
height: 100%;
bottom: 0;
-webkit-transition: height 0.9s ease;
transition: height 0.9s ease;
}
<div class="parent">
<img class="child1" src="https://picsum.photos/200/300">

I'm trying to create a sidebar like this:
function show_menu(){
document.querySelector('#sidebar').classList.toggle('sidebar_open');
document.querySelector('#blackscreen').classList.toggle('blackscreen_open');
}
#hamburger {
width: 5rem;
height: 5rem;
background-color: red;
}
#header_wrapper {
display: block;
}
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
transition: width 0.25s;
}
.sidebar_open {
width: 50% !important;
background-color: green;
display: grid !important;
}
#blackscreen{
position:fixed;
top:0;
right:0;
width:100vw;
height:100vh;
transition: background-color 0.25s;
}
.blackscreen_open {
background-color: rgba(0, 0, 0, 0.5);
}
<div id="hamburger" onclick="show_menu()">click here</div>
<div id='blackscreen' onclick="show_menu()"></div>
<span id='sidebar'>
</span>
but the sidebar transition only works one way,
My best guess is that the transition requires 2 classes to operate
but since I've removed one class the transition back might not be taking place
so I tried the solution according to this question like this:
function show_menu(){
document.querySelector('#sidebar').classList.toggle('sidebar_open');
document.querySelector('#blackscreen').classList.toggle('blackscreen_open');
}
#hamburger {
width: 5rem;
height: 5rem;
background-color: red;
}
#header_wrapper {
display: block;
}
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
}
#sidebar:not(.sidebar_open) {
transition: width 0.25s;
}
.sidebar_open {
width: 50% !important;
background-color: green;
display: grid !important;
}
#blackscreen {
position: fixed;
top: 0;
right: 0;
width: 100vw;
height: 100vh;
transition: background-color 0.25s;
}
.blackscreen_open {
background-color: rgba(0, 0, 0, 0.5);
}
<div id="hamburger" onclick="show_menu()">click here</div>
<div id='blackscreen' onclick="show_menu()"></div>
<span id='sidebar'>
</span>
but as you can see even that didn't work
I'm pretty sure I'm missing something obvious but any & all help is greatly appreciated!
I'm fairly certain that the transition IS working but you're not seeing it because when it's not open, your sidebar doesn't have a background colour, and since you don't have a transition setting for your background attribute, when you remove the sidebar_open class the background colour IMMEDIATELY reverts to none and the width transition becomes invisible.
You should be able to test this by moving background-color: green; from the .sidebar_open class to the #sidebar element.
You need to have the background-color set even when the sidebar is not open. Otherwise, when the class is removed, you can no longer see it even though the width is being animated.
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
background-color: green;
transition: width 0.25s;
}
function show_menu() {
document.querySelector('#sidebar').classList.toggle('sidebar_open');
document.querySelector('#blackscreen').classList.toggle('blackscreen_open');
}
#hamburger {
width: 5rem;
height: 5rem;
background-color: red;
}
#header_wrapper {
display: block;
}
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
background-color: green;
transition: width 0.25s;
}
.sidebar_open {
width: 50% !important;
display: grid !important;
}
#blackscreen {
position: fixed;
top: 0;
right: 0;
width: 100vw;
height: 100vh;
transition: background-color 0.25s;
}
.blackscreen_open {
background-color: rgba(0, 0, 0, 0.5);
}
<div id="hamburger" onclick="show_menu()">click here</div>
<div id='blackscreen' onclick="show_menu()"></div>
<span id='sidebar'></span>
Currently, I am building a style guide and I have a question about the transition of an element. Imagine you have a container with two elements besides each other. Both have 50% width. The left element should always be visible, but the right element slides from the right into its 50% width. How can I achieve something like this? I am a bit overwhelmed with the top, bottom, left, right, position:absolute properties.
The html would look like this:
<div class="module-container">
<div class="first-element">
<div class="second-element">
</div>
and the css like this:
.module-container {
display: flex;
}
.first-element {
width: 50%;
}
.second-element {
width: 50%;
}
which properties does the second Element need in the first place? And which should I add via JavaScript after pressing, for instance, a button?
try using jQuery and transitions
$('#btn').click(function() {
$('.secondElement').toggleClass("slide");
});
.moduleContainer {
display: flex;
height: 100px;
overflow: hidden;
}
.firstElement {
position: relative;
width: 50%;
border: 1px solid #000;
}
.secondElement {
position: relative;
width: 50%;
border: 1px solid #000;
left: 100%;
transition: left 1s;
}
.secondElement.slide {
left: 0;
}
#btn {
display: block;
margin-top: 20px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="moduleContainer">
<div class="firstElement"></div>
<div class="secondElement"></div>
</div>
<button id="btn">Click Here</button>
.moduleContainer {
display: flex;
height:100px;
}
.moduleContainer > * {
border:1px solid red;
box-sizing:border-box;
overflow:hidden;
}
.firstElement {
height: 100%;
width: 50%;
}
.secondElement {
height: 100%;
width: 0%;
transition:width 0.3s ease;
}
.moduleContainer:hover .secondElement {
width:50%;
}
<div class="moduleContainer">
<div class="firstElement"></div>
<div class="secondElement"></div>
</div>
I have achieved it with pure CSS.I think it's good to have a bar, so the user can hover it and expand.I hope it will help you.
.moduleContainer{ display: flex;flex-flow: row nowrap; }
.firstElement{ background-color:blueviolet;flex:1;height:100px;position:relative;max-width: 50%; }
.secondElement{ background-color:aqua;height:100px;flex:1;max-width:1%;position:relative;transition:1s ease;left:48%; }
.secondElement:hover{ background-color: chartreuse;left:0px;max-width:50%; }
<div class="moduleContainer">
<div class="firstElement">First Element</div>
<div class="secondElement"></div>
</div>
You can use a negative value for margin-left of the .second-element.
.module-container {
display: flex;
height: 50px;
overflow: hidden;
}
.module-container:hover .second-element {
right: 0;
}
.first-element {
flex: 0 0 50%;
background: #f90;
}
.second-element {
flex: 0 0 50%;
background: #0f9;
right: -50%;
transition: all .6s ease;
position: relative;
}
<div class="module-container">
<div class="first-element"></div>
<div class="second-element"></div>
</div>
Or you can use position: absolute and animate the left property
.module-container {
position: relative;
height: 50px;
overflow: hidden;
}
.module-container:hover .second-element {
right: 0;
}
.first-element {
width: 50%;
background: #f90;
position: absolute;
left: 0;
top: 0;
bottom: 0;
}
.second-element {
background: #0f9;
width: 50%;
position: absolute;
right: -50%;
top: 0;
bottom: 0;
transition: all .6s ease;
}
<div class="module-container">
<div class="first-element"></div>
<div class="second-element"></div>
</div>

Just to Help out others, I fixed the issue using area mapping...
I am just playing around trying to get a simple 3 slide slider working but run into some issues with the javascript. All i want to happen is on click of the slider colour i would like the current slider to slide out and the selected one to slide in. I am trying to do it by adding an active class to the slider number that I have clicked to show. I just cant quite work out where I have gone wrong. I don't want to use jQuery as I am trying to learn vanilla javascript.
Thanks as always

You're only adding an event listener to the first box and you're toggling every box's active class in order, and the last one is yellow, so you result with a yellow background.
querySelector returns the first DOM element it finds, which is the red box.
For the functionality that you want, you have to add event listeners to each box (querySelectorAll)
window.onload = onPageLoad();
function onPageLoad() {
document.querySelector('.red').classList.add('active');
};
document.querySelector('.redbox').addEventListener('click', function() {
document.querySelector('.red').classList.add('active');
document.querySelector('.green').classList.remove('active');
document.querySelector('.yellow').classList.remove('active');
});
document.querySelector('.greenbox').addEventListener('click', function() {
document.querySelector('.red').classList.remove('active');

document.querySelector('.yellow').classList.remove('active');

document.querySelector('.yellowbox').addEventListener('click', function() {

Here is a primitive example solution. It's overly verbose but shows you what is needed. This can be condensed.
To get an idea of how it can be condensed, all three listeners CAN be condensed into a single listener how you had it, listen just to the .box selector. But if you do that, you need a way to identify which box was clicked. This can be done via a data attribute or by looking at the html text. A data attribute would be my preferred method, as it separates the content from the logic a bit, but either would work.
Another less verbose solution:
window.onload = onPageLoad();
function onPageLoad() {
document.querySelector('.red').classList.add('active');
};
var boxes = document.querySelectorAll('.box');
for (var i = 0; i < boxes.length; i++) {
boxes[i].addEventListener('click', toggleSections);
}
var colors = ['red', 'green', 'yellow'];
function toggleSections(ev) {
var color = ev.currentTarget.innerText;
for (var c = 0; c < colors.length; c++) {
var colorElem = document.querySelector('.' + colors[c]);
if (colors[c] != color) {
colorElem.classList.remove('active');
} else {
colorElem.classList.add('active');
}
}
}

To achieve expected result, use below option
Use one section to avoid looping of section elements
Use querySelectorAll or elementsByClassName instead of querySelector to fetch all elements in array
Use forEach to loop through all elements of class- box and add addEventListener and run another loop with forEach for span elements
Use classList to add or remove
window.onload = onPageLoad();
function onPageLoad() {
document.querySelector('.red').classList.add('active');
};
// use querySelectorAll to get all elements of class-box and forEach to loop through
document.querySelectorAll('.box').forEach(function(ele){
//Add clici event through addEventListener
ele.addEventListener('click', function() {
// use another querySelectorAll to get all elements of tag span and forEach to loop through
document.querySelectorAll('span').forEach(function(e){
e.classList.remove('active');
//use querySelector for section element and empty classList to remove active and red/green/yellow class names
document.querySelector('section').className ='';
});
//toggle active class for clicked element
ele.children[0].classList.toggle("active");
//add active class for section
document.querySelector('section').classList.add('active');
//add class red/yellow/green using span innerHTML
document.querySelector('section').classList.add(ele.children[0].innerHTML);
});
});
