We open popup window. We want to slide this off the screen. The "Right" and "Top" parts can be made as much as possible. How can we slide out of the screen?
var wind = window.open("https://www.google.com","","width=50,height=50,left=1500%,top=1000%");
While I'm not exactly sure about your particular use case, but by toggling opacity and right/left, you can achieve the "effect" of the div going out of the screen.
function move() {
let element = document.getElementById("box");
element.style.transform = "translate(-400px)";
element.style.right = 0;
element.style.opacity = 0;
}
#box {
width: 300px;
height: 200px;
background: blue;
margin-bottom: 20px;
color: white;
transition: all 0.3s ease;
opacity: 1;
position: absolute;
}
#btn {
margin-top: 300px;
}
<div id="box">Hello</div>
<button id="btn" onclick="move()">Click</button>

I'm new to the web development world and wanted to know if there is a way to disable background scrolling.
I've tried z-index for the pop-up to display above all the elements, but some background content was getting overlapped with the pop-up.
I'm not much familiar with JS but was not able to get any help.
Below please find my code
body {
height: 200vh;
}
.bg-noscroll {
}
.overlay {
position: fixed;
top: 0;
bottom: 0;
left: 0;
right: 0;
background: rgba(0, 0, 0, 0.7);
transition: opacity 500ms;
visibility: hidden;
opacity: 0;
}
.overlay:target {
visibility: visible;
opacity: 1;
}
.popup {
transform: translateY(-60px);
margin: 70px auto;
padding: 20px;
background: #fff;
border-radius: 5px;
width: 30%;
position: relative;
transition: all 5s ease-in-out;
}
.popup .close {
position: absolute;
top: 20px;
right: 30px;
transition: all 200ms;
font-size: 30px;
font-weight: bold;
text-decoration: none;
color: #333;
}
.content {
height: 250px;
}
.popup .content {
overflow-y: scroll;
}
#media screen and (max-width: 700px){
.popup{
width: 70%;
}
<body class="bg-noscroll bg-scroll">
<span><a class="popupBG-Disable" href="#popup">Full Recipe</a></span>
<div id="popup" class="overlay">
<div class="popup">
<h3>Foxtail Millet Porridge:</h3>
<a class="close" href="#">×</a>
<div class="content">

Thank you for your help!
I have a live codepen with your original code so you can just copy and paste if you wish.
Using Jquery, we can enable and disable overflow using some simple code:
const modal = document.querySelector("#btn");
const body = document.querySelector("body");
const showModal = function (e) {
modal.classList.toggle("hidden");
if (!modal.classList.contains("hidden")) {
body.style.overflow = "hidden";
} else {
body.style.overflow = "hidden";
}
}; // just reversed for re-enabling scroll, as seen in the codepen
Currently, you have to make use of javascript and add or remove the scrollbar-properties or css-class using a hashchange event-listener for example:
window.addEventListener("hashchange", event => {
const newHash = new URL(event.newURL).hash,
el = document.getElementById(newHash.substr(1));
if (el && el.classList && el.classList.contains("overlay")) {
document.body.style.overflow = "hidden";
// or document.body.classList.add("bg-noscroll");
} else {
document.body.style.overflow = "";
// or document.body.classList.remove("bg-noscroll");
}
});
Starting from chromium 101 the support for the :has()-selector has been implemented (experimental flag only) and the current chromium 105 dev channel brings the :has()-selector enabled by default.
With the has()-selector it will be possible using:
body:has(.overlay:target) {
overflow: hidden;
}
Keep also mind, it may take some more time for other browsers to implement the has()-selector. Therefor the best would be to stick with the javascript method for a while.
What I'm trying to achieve here is that when I scroll on a particular div here .ball, it should scale up to 1.5.
but when I'm not scrolling on that ball div it should shrink down to it's original height and width.
Here I'm using window method to do this trick and as soon as I scroll ball scale up which isn't what I'm trying to do. What can I use instead of window method and is there any other approach to do achieve this?
const ball = document.querySelector('.ball');
window.addEventListener('scroll', ()=> {
if (scroll) {
ball.classList.add('active');
} else {
ball.classList.remove('active');
}
});
.ball {
height: 200px;
width: 200px;
border-radius: 100%;
background-color: orange;
}
.ball.active {
transform: scale(1.5);
position: fixed;
}
body {
height: 150vh;
}
<div class="ball"></div>
I would use a setTimeout function to remove the class after a short period after the scroll. Do not forget to clear the timeout otherwise it will lead to weird behaviour. (as suggested by Lakshya when I was answering to the question).
To make the ball smoothly transition, I would add a css transition as shown bellow.
const ball = document.querySelector('.ball');
const container = document.querySelector('.container')
let scrollTimeout;
container.addEventListener('scroll', ()=> {
ball.classList.add('active');
clearTimeout(scrollTimeout);
scrollTimeout = setTimeout(()=> ball.classList.remove('active'), 100);
});
.ball {
height: 200px;
width: 200px;
border-radius: 100%;
background-color: orange;
transition: transform 0.3s ease;
position: fixed;
top: 50px;
left: 50px;
}
.ball.active {
transform: scale(1.5);
}
.container{
width: 100%;
background: red;
overflow: scroll;
height: 500px;
}
.inside_container{
position: relative;
width: 100%;
height: 2000px;
}
<div class="container">
<div class="inside_container">
<div class="ball"></div>
</div>
</div>
One of the approaches could be delaying the removal of .active class on ball by 200ms such that each time you try to scroll again, the timer is cleared and a new one starts to do the same. A debounce approach in a nutshell.
const ball = document.querySelector('.ball');
let scrollTimeout;
window.addEventListener('scroll', ()=> {
ball.classList.add('active');
clearTimeout(scrollTimeout);
scrollTimeout = setTimeout(()=> ball.classList.remove('active'),200);
});
.ball {
height: 200px;
width: 200px;
border-radius: 100%;
background-color: orange;
}
.ball.active {
transform: scale(1.5);
position: fixed;
}
body {
height: 150vh;
}
<div class="ball"></div>
I have an overlay which contains a div and a couple of other elements.
I'm trying to get the div to scale up with a transition upon opening the overlay.
HTML
<div id="item-overlay" class="overlay">
<div id="item-panel" class="overlay-panel">
<div class="overlay-panel-top">
<h1 id="item-panel-title" class="main-panel-txt">Item</h1>
<img class="close" src="images/close.png" alt="" onclick="closeOverlay()">
</div>
</div>
</div>
CSS
.overlay{
display: none;
align-items: center;
justify-content: center;
position: fixed;
width: 100%;
height: 100%;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: rgba(0, 0, 0, 0.5);
z-index: 2;
}
#item-panel{
width: 0%;
height: 75%;
background: white;
border-radius: 15px;
padding: 25px;
-webkit-transition: width 0.25s ease-in-out;
}
JS
var itmOverlay = document.getElementById("item-overlay");
var itemPanel = document.getElementById("item-panel")
function itemOverlay(){
itmOverlay.style.display = "flex";
itemPanel.style.width = "50%";
}
function closeOverlay(){
itmOverlay.style.display = "none";
itemPanel.style.width = "0%";
}
This doesn't work, the of div just appears at full-size when opening the overlay. However, I can past the code above into the console and the transition will work.
I'm really not sure what's going on here.
I'm unsure why the code above doesn't work, but I managed to get the desired effect by changing the width in a separate function that's called after the overlay is enabled.
function itemOverlay(){
itmOverlay.style.display = "flex";
setTimeout(openOverlayTimer, 10);
}
function openOverlayTimer(){
itemPanel.style.width = "50%";
}
I've been trying to create the following animation:
(1) I have a button consisting of a white 100x100 box on top of a black 100x100 box.
(2) Clicking on the button makes the white box disappear into the black box.
(see the result here)
// html
<div class="button">
<div class="white u-on-top"></div>
<div class="black"></div>
</div>
// css
.button {
width: 100px;
height: 100px;
margin: 10px;
position: relative;
display: inline-block;
.white {
width: 100%;
height: 100%;
background: #fff;
border: 1px solid #000;
position: absolute;
transition: .5s;
}
.black {
width: 100%;
height: 100%;
background: #000;
border: 1px solid #000;
}
}
.u-on-top {
z-index: 1;
}
.u-at-bottom {
z-index: -1;
}
// javascript
var btn = document.querySelector(".button");
var btnState = false;
btn.addEventListener("click", () => {
var btnw = btn.querySelector(".white");
if (!btnState) {
btnw.style.transform = "scale(0)";
btnState = true;
} else {
btnw.style.transform = "scale(1)";
btnState = false;
}
})
(3) What I've unsuccessfully been trying to do is to also make the black box disappear into the white box when clicked on.
So:
clicking on the white box makes it disappear into the black box
clicking on the black box makes it disappear into the white box
clicking on the white box makes it disappear into the black box
And so on...
My idea was to obtain the effect by modifying the z-index of the boxes when clicked on, using the utility classes u-on-top and u-at-bottom (eg the black box is brought to the top after the white box disappears), but I got some weird results.
You can try to adjust some transition, the trick is to add a delay to z-index so it changes after the scale effect. I have also change the JS code and reduced the CSS:
var btnW = document.querySelector(".white");
var btnB = document.querySelector(".black");
var btnState = false;
btnW.addEventListener("click", () => {
btnB.classList.remove('hide');
btnW.classList.add('hide');
btnW.classList.remove('u-on-top');
btnB.classList.add('u-on-top');
})
btnB.addEventListener("click", () => {
btnW.classList.remove('hide');
btnB.classList.add('hide');
btnB.classList.remove('u-on-top');
btnW.classList.add('u-on-top');
})
.button {
width: 100px;
height: 100px;
margin: 10px;
position: relative;
display: inline-block;
cursor: pointer;
}
.button>div {
width: 100%;
height: 100%;
border: 1px solid #000;
position: absolute;
transition: transform 0s, z-index 0s 0.5s;
z-index:0;
}
.button .white {
background: #fff;
}
.button .black {
background: #000;
}
.button>div.hide {
transform:scale(0);
transition: transform .5s, z-index 0s 0.5s;
}
.button>div.u-on-top {
z-index:1;
}
<div class="button">
<div class="white u-on-top"></div>
<div class="black"></div>
</div>
I'm trying to switch images in a div every few seconds
the current code works, but there are 2 things that I want to change and I need your help for that:
The div resizes to the current image displaying in it, I want it to always use the size of the bigger image
I want to fade between the images instead of just switching
Thanks for reading, I hope you can help me.
This is what I got so far:
var imgIndex = 0;
setInterval(function() {
images[imgIndex].style.display = "none";
imgIndex++;
if (imgIndex >= images.length) {
imgIndex = 0;
}
images[imgIndex].style.display = "block";
}, 5000);
.imageDisplay {
display: inline-block;
width: 100%;
background-Color: white;
color: black;
border-radius: 5%;
margin: 2px;
padding: 1px;
opacity: 0.5;
transition-duration: 0.5s;
}
.imageDisplay:hover {
opacity: 1;
}
.Image {
width: 99%;
height: auto;
margin: 1px;
padding: 1px;
border-radius: 5%;
cursor: pointer;
display: none;
}
<div class="imageDisplay">
<p>Description</p>
<img class="Image"></img>
<img class="Image"></img>
</div>
Firstly you could set the div to be equal to the size of the large image and then use:
object-fit: cover;
object-position:center;
As for switching you could use:
transition: opacity .3s linear;
Read here on how to exactly implement the transitions. My suggestion would be stacking them all up and fading them in one by one every few seconds.
