I would like to ask everyone. I hope to make an effect. When the page is loaded, I can delay the transparency of the background for 2 seconds, and let the duck in the middle hide from the middle of the screen and slowly enlarge and appear.
But I have just learned javascript and CSS, and now I found a problem that the duck doesn't seem to be enlarged from the center point. I don't know why?
In addition, I want to trigger the animation with a delay of two seconds after the page is loaded. Is this way of writing OK? Since I'm a beginner, I don't know if this way of writing is correct?
Thanks for watching my question
let wrap = document.querySelector('.wrap');
let duck = document.querySelector('.duck');
window.onload = function() {
setTimeout(change, 1000);
// wrap.style.opacity = "0.6"
}
function change() {
wrap.style.opacity = "0.6";
wrap.transition = "1.2s";
duck.style.transform = "scale(1.6)";
}
.wrap {
position: relative;

Try to put the scale of duck to 0, or opacity of duck to 0 from the start, or apply css animation to .duck class. Not sure what are you trying to achieve.

How to stop/start CSS animation
Background-Info
I'm trying to make a loader for my website where when someone makes a search to my API it will popup the loader then after the table gets built it will stop the loading animation. I'm not good with javascript and I'm just trying to create this side project so I don't completely know how this stuff works. I did see another stack overflow post about this topic but it didn't apply to me because the way they called the CSS animation was different
I followed a tutorial for this loader here he shows how to stop it but he doesn't show how to start it, but it doesn't stop for me
What I tried
Like I was saying above I'm not good with javascript so I wasn't sure what i should try but like in the video I tried to make the CSS display = None and also i tried to remove the HTML entirely ( you can see it below in the code)
End goal
My end goal is to have a javascript function like start_loading() and stop_loading() I can call to stop and start the loading at any time
Code
function start_load() {
let spinnerWrapper = document.querySelector('.spinner-wrapper')
console.log(document.querySelector('.spinner-wrapper'))
window.addEventListener('load', function() {
spinnerWrapper.style.display = 'none';
// spinnerWrapper.parentElement.removeChild(spinnerWrapper)
});
}
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
html {
font-size: 10px;
}
.spinner-wrapper {
width: 100%;
height: 100%;
/* background-color: #151515; */
position: absolute;
top: 0;
left: 0;
z-index: 9999;
display: flex;
align-items: center;
justify-content: center;
}
.spinner {
position: relative;
width: 8rem;
height: 8rem;
border-radius: 50%;
}
.spinner::before,
.spinner:after {
content: "";
position: absolute;
border-radius: 50%;
}
.spinner:before {
width: 100%;
height: 100%;
background-image: linear-gradient(90deg, #212529 0%, white 100%);
animation: spin .5s infinite linear;
}
.spinner:after {
width: 90%;
height: 90%;
background-color: white;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
#keyframes spin {
to {
transform: rotate(360deg);
}
}
/*Simulate page content*/
.main-content {
width: 100%;
height: 100vh;
background: url("https://source.unsplash.com/random/4000x4000") center no-repeat;
background-size: cover;
}
<body onload="verifySession(), start_load()">
<div class="spinner-wrapper">
<div class="spinner">
</div>
</div>
const start_load = function () {
document.querySelector('.spinner-wrapper').style.display = "block"
}
const end_load= function () {
document.querySelector('.spinner-wrapper').style.display = "none"
}
You can change .spinner-wrapper by any class you want. Those function will set fisrt html tag have .spinner-wrapper class to display : block or display : none
Hope this help for you
Your question is not very clear on when you want to start and stop the loader but from my understanding you have an api and you want the loader to show when someone calls your api so in this particular case you want to work with DOM event listeners (at least when you start your search by a click of a button or when you press enter on your keyboard) you can read more on event listeners here:
https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener and here:
https://www.w3schools.com/js/js_htmldom_eventlistener.asp
As for stopping the event you will want to call the stop function once data are returned from your API
I've created a little codesandbox for you with two buttons to start and stop the loader as a simple example of how to use event listeners which you can find here: https://codesandbox.io/s/happy-rain-e9w3mz
I have a background-image with a button in the center. When I press the button, I want to zoom in on the background-image. When it's zoomed in I'm creating multiple charts using chartist.js. For a while now I've had the problem that the chart isn't registering the width and height I have assigned to it and I have finally figured out that it's the zoom effect causing the problem. I have no idea why this happens and I would like to find a different way than using transform:scale() to create the zoom effect. Any help would be appreciated!
The transform property changes the object without redrawing the page, which is a great performance boost since it reduces all the layout computations. If you don't want to use it, you can try the 'background-size' property.
First, set up your background image in css to have separate properties:
<div class='bg-img'></div>
<style>
.bg-img{
background-image: url(www.img.com/img.jpg);
background-position: center center;
background-repeat: no-repeat;
background-size:100%;
width: 200px;
height:200px;
}
</style>
Then use javascript to change the background-size
<script>
function zoomit() {
document.querySelector('.bg-img').style.backgroundSize = "200%";
}
</script>
you can try it by increasing the width
let btn = document.querySelector(".btn");
let image = document.querySelector(".image");
btn.addEventListener("click", function(e){
image.classList.add("zoom");
});
.img {
position: relative;
width: 200px;
overflow: hidden;
}
.image {
width: 100%;
height: 100%;
transition: width 0.1s linear;
}
.btn {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
.zoom {
width: 120%;
}
<div class="img">
<img class="image" src="https://i.picsum.photos/id/222/536/354.jpg?hmac=0F40OROL8Yvsv14Vjrqvhs8J3BjAdEC8IetqdiSzdlU" alt="">
<button class="btn">CLICK</button>
</div>
Working Fiddle
Hi i'm trying to make it so when someone hovers on an image it makes the play button turn up only on that image, I have a few different effects on the image so I've had to make it so that when i hover one class it shows another one with it too using java, only problem is I have 9 images that need to show the play button on hover indivudally but when I hover over 1 image it shows the play icon on all of the images at once,
Is there an easier way to do this so that the play icon only shows when I'm hovering the one specific image?
Javascript:
$(".portbg1").hover( function () {
$(this).addClass("active");
$(".playbutton").addClass("active");
}, function (){
$(this).removeClass("active");
$(".playbutton").removeClass("active");
});
HTML:
<div class="port_item"><div class="playbutton"></div><div
class="portbg1"><div class="port_item_title" data-modal="#modalOne"> .
<h4>Showreel</h4></div></div></div>
There's also portbg2, portbg3, portbg4 etc... portbg9
CSS:
.playbutton {
position: absolute;
background-image: url(IMAGES/openicon.png);
background-size: 80px 80px;
background-repeat: no-repeat;
background-position: center center;
width: 80px;
height: 80px;
left: 50%;
margin-left: auto;
margin-right: auto;
top: 50%;
transform: translate(-50%,-50%);
z-index: 1;
opacity: 0;
overflow: hidden;
transition: all 0.2s;
}
.playbutton:hover {
opacity: 1;
}
.active {
opacity: 1;
}
Just doing :
$(this).siblings('.playbutton').addClass("active");
doing the same on remove class.
So finally would be:
$(this).addClass("active").siblings('.playbutton').addClass("active");
EDIT: This is not the same as this post, How to reverse an animation on mouse out after hover. The difference being that in this case the state of the transition (how far it has progressed) is essential unlike in the aforementioned post that completely ignores it.
TL;DR: How to animate/transition an element back to it's original state after animation ends?
Hello,
I'm trying to make animate panels so that they "float" when hovered. My problem is that the mouse leaves the panel, instead of transitioning back to it's original state, it jumps instantly back.
A heavily simplified version of this can be found in the snippet available below.
body {
width: 100%;
height: 100vh;
margin: 0;
padding: 0;
display: flex;
justify-content: center;
align-items: center;
}
div {
width: 50px;
height: 50px;
background-color: red;
}
div:hover {
animation: float 2s infinite ease;
}
#keyframes float {
0%, 100% {
transform: none;
}
50% {
transform: translateY(-20px);
}
}
<html>
<head>
<title>animate to orignal position</title>
</head>
<body>
<div id='box'></div>
</body>
</html>
As you can see, floating it triggers a smooth animation that resembles a floating motion, however, it is abruptly interrupted as the mouse leaves the box and the animation stops.
So my question is: Is there a way to allow the box to transition back to it's original state, preferably without using JavaScript (although all suggestions are appreciated).
(This has probably been answered somewhere online and if that is the case, then I am truly sorry but I have been unable to find a proper solution to my problem. Please add duplicate if you find an applicable solution.)
Thanks.
You're going to have to use JavaScript and CSS Transitions:
var box = document.getElementById('box')
var timer
box.addEventListener('mouseenter', function () {
box.classList.add('up')
timer = setInterval(function () {
box.classList.toggle('up')
}, 1000)
})
box.addEventListener('mouseleave', function () {
clearInterval(timer)
box.classList.remove('up')
})
body {
width: 100%;
height: 100vh;
margin: 0;
padding: 0;
display: flex;
justify-content: center;
align-items: center;
}
div {
width: 50px;
height: 50px;
background-color: red;
transition: transform 1s ease;
}
div.up {
transform: translateY(-20px);
}
<html>
<head>
<title>animate to orignal position</title>
</head>
<body>
<div id='box'></div>
</body>
</html>
Hi guys I was trying to swap the background of two images down the footer section of my website using skrollr.js (https://github.com/Prinzhorn/skrollr). For some reason it won't scroll at all. I am trying to create a parallax site that has fixed position on the part below.
See image: http://prntscr.com/6yrckx
Here's the Markup of that part:
<div id="starynight"
data-bottom-top="opacity: 1; background: !url(images/sunny.jpg); background-size: cover;"
data--40-top="opacity: 0.5; background: !url(images/night.jpg); background-size: cover;"
data--50-top="opacity: 0; background: !url(images/night.jpg); background-size: cover;"
data--60-top="opacity: 0.5; background: !url(images/night.jpg); background-size: cover;"
data--70-top="opacity: 1; background: !url(images/night.jpg); background-size: cover;"
>
</div>
While here's the CSS:
#starynight{
background: url('../images/sunny.jpg') no-repeat center;
width: 100%;
height: 307px;
background-size: cover;
}
#road{
background: url('../images/road.jpg') no-repeat center;
width: 100%;
height: 145px;
background-size:cover;
}
#car{
background: url('../images/car.png') no-repeat center;
width: 325px;
height: 125px;
display: block;
position: absolute;
z-index: 9999;
left: 950px;
top: 2100px;
}
My issue here is that when I scroll this part of my website it should swap the images of the sunny.jpg and night.jpg while the car is moving from right to left and also this background image must be fixed in position. For some reason my codes won't just work. Any idea what went wrong?
See my website here: http://goo.gl/aNOCiJ
Animating backgrounds is not like animating positions or "number" data. You can't just transform one background into another by fading them (actually Firefox somehow can animate the transition, but lets not depend on that).
A solution to your problem is having 2 diferent divs for, 1 for your night scene, and other for your sunny sky just in the same position, one over the other and with the sunny one with a higher z-index.
Then what you need to animate on scroll is the opacity of the sunny sky, what makes the night scene appear.
Also I found that your level of scroll isn't enough to fade the opacity of the sunny sky completly, it ends in 0.603448.
Hope it helps, please tell me if this worked.
As stated already, background images can't be animated, only background colors. So you'll have to lay both images on top of each other and fade the top layer in like this -
