visibility hidden after playing animation

I'm trying to add effects on modal.
I want to make like this:
When modal--show class added, visibility set to visible and opacity continues to grow 0% to 100%.
When modal--show class removed, opacity continues to decrease 100% to 0%, and after then, visibility set to hidden.
Showing modal animation works well, but hiding modal animation doesn't. When hiding animation plays, visibility becomes hidden immediately when animation starts.
How to set visibility: hidden after opacity: 0% with CSS or pure JS?
JSFiddle: https://jsfiddle.net/p1gtranh/1/
document.querySelector('.open').addEventListener('click', () => {
document.querySelector('.modal').classList.add('modal--show');
});
document.querySelector('.close').addEventListener('click', () => {
document.querySelector('.modal').classList.remove('modal--show');
});
.modal {
display: flex;
align-items: center;
justify-content: center;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.3);
visibility: hidden;
opacity: 0%;
}
.modal--show {
animation: show 0.5s both;
visibility: visible;
}
#keyframes show {
0% {
visibility: hidden;
opacity: 0%;
}
1% {
visibility: visible;
}
100% {
opacity: 100%;
}
}
<button class="open">open</button>
<div class="modal">
<button class="close">close</button>
</div>

I would probably scrap the whole animation and just make a simple transition instead.
In this case, transition is specified in a shorthand. The associated properties are:
transition-timing-function: ease-in-out - how the transition should be played, this value will play an easing fading transition when both opening and closing the modal.
transition-property: all - what property is associated with the transition. Since we are transitioning both the opacity and visibility-properties, using all will select both of these.
transition-duration: 0.5s - how long the transition should last.
More on the transition-shorthand here
document.querySelector('.open').addEventListener('click', () => {
document.querySelector('.modal').classList.add('modal--show');
});
document.querySelector('.close').addEventListener('click', () => {
document.querySelector('.modal').classList.remove('modal--show');
});
.modal {
display: flex;
align-items: center;
justify-content: center;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.3);
visibility: hidden;
opacity: 0%;
transition: all 0.5s ease-in-out;
}
.modal--show {
visibility: visible;
opacity: 100%;
}
<button class="open">open</button>
<div class="modal">
<button class="close">close</button>
</div>

Is there a way to make an element spin around without a variable telling how far it has already turned?

I have an experimental website that plays music, and I want the forward and backward buttons to spin when you click them. But, I also don't want to have 2 variables to be how far they have turned, or a function to get how far they have turned from the CSS transform property. They have a transition, for hover effects. I have tried
backward.classList.add("notrans");
backward.style.transform = "rotateZ(0deg)";
backward.classList.remove("notrans");
backward.style.transform = "rotateZ(-360deg)";
and some closely related things, and also have a setTimeout to reset it afterwards, which it too long for a post.

Animate is what you are searching for.
This should be a working example: (Tested in FF and Chrome)
/* THIS IS A JAVASCRIPT CLASS THAT ADDS AND
REMOVES THE CSS CLASS FROM YOUR ELEMENT
USING THE ELEMENT'S ID VALUE TO REFERENCE. */
function startStop(strstp) {
var infinite = document.getElementById("imSpinning");
var once = document.getElementById("imSpinningOnce");
if(strstp == 1)
{
infinite.classList.add("spin");
once.classList.add("spinOnce");
timer = setTimeout(function() {
once.classList.remove("spinOnce");
},1000);
}
else
{
infinite.classList.remove("spin");
once.classList.remove("spinOnce");
}
}
/* THIS IS THE CSS CLASS THAT CREATES INFINITE ROTATION */
.spin {
-webkit-animation:spin 1s linear infinite;
-moz-animation:spin 1s linear infinite;
animation:spin 1s linear infinite;
}
#-moz-keyframes spin { 100% { -moz-transform: rotate(360deg); } }
#-webkit-keyframes spin { 100% { -webkit-transform: rotate(360deg); } }
#keyframes spin { 100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); } }
/* THIS IS THE CSS CLASS THAT ROTATES ONCE */
.spinOnce {
-webkit-animation:spin 1s linear;
-moz-animation:spin 1s linear;
animation:spin 1s linear;
}
#-moz-keyframes spinOnce { 100% { -moz-transform: rotate(360deg); } }
#-webkit-keyframes spinOnce { 100% { -webkit-transform: rotate(360deg); } }
#keyframes spinOnce { 100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); } }
<div style="width: 100px; height: 30px; background-color: green; color: white; margin: 20px; text-align: center; cursor: pointer;" onclick="startStop(1)">
GO
</div>
<div style="width: 100px; height: 30px; background-color: red; color: white; margin: 20px; text-align: center; cursor: pointer;" onclick="startStop(0)">
STOP
</div>
<!-- ELEMENT TO ROTATE INFINITLY WITH "spin" CLASS -->
<div id="imSpinning" class="spin" style="position: absolute; top: 10px; right: 30px; height: 140px; width: 140px; background-image: url(https://icons.iconarchive.com/icons/thehoth/seo/256/seo-web-code-icon.png); background-size: 100% 100%; background-position: center center; border-radius: 50%; overflow: hidden;"></div>
<!-- ELEMENT TO ROTATE ONCE WITH "spin" CLASS -->
<div id="imSpinningOnce" class="spinOnce" style="position: absolute; top: 10px; right: 200px; height: 140px; width: 140px; background-image: url(https://icons.iconarchive.com/icons/thehoth/seo/256/seo-web-code-icon.png); background-size: 100% 100%; background-position: center center; border-radius: 50%; overflow: hidden;"></div>
Simply copy the CSS class above to the style section/sheet of your page and modify it as needed. Ensure you reference the class in your html element.
Also I edited in a small JavaScript class that add/removes the spin class from the DIV element if it helps you in starting and stopping the animation.
Hope this helps, and best of luck!

Clicking trough a visibility:hidden element

I made a div with 2 elements inside: an image and an another div (about). The image is hiding the about div.
Is that possible to make elements which are in the about div clickable when the image disappear with a hover property ?
Thanks in advance !
Also, here's my code but the elements aren't clickable
#logo {
opacity: 1;
visibility: visible;
margin-top: 12.5px;
-webkit-transition: opacity 600ms, visibility 600ms;
-o-transition: opacity 600ms, visibility 600ms;
-moz-transition: opacity 600ms, visibility 600ms;
transition: opacity 600ms, visibility 600ms;
}
.blue_border:hover #logo {
opacity: 0;
visibility: hidden;
}
.blue_border {
width: 625px;
height: 625px;
background-image: url("./border.png");
background-repeat: no-repeat;
background-position: 50%;
}
#about {
z-index: -1;
position: relative;
margin-top: -605px;
width: 600px;
height: 600px;
border-radius: 100%;
background-color: #25B8EE;
}
<div class="blue_border">
<img id="logo" src="./logo.png" />
<!-- Img is "on" the about div" -->
<div id="about">
I want to be clicked :-(
</div>
<div class="la-ball-scale-multiple">
<div></div>
<div></div>
<div></div>
</div>
</div>

I don't think I understand it completely, but you cannot click under another element but you can use CSS display: none attr or you do this in a fake way. You can listen to the top element for this and check other conditions on javascript.

As mentioned in the comments, you may can use the pointer-events: none on the overlay to cause it to not receive click events, and allow them to pass through.
function whoWasClicked(e) {
console.log(`${e.target.id} was clicked!`);
};
document.querySelector('#lowerElement').addEventListener('click', whoWasClicked);
document.querySelector('#upperElement').addEventListener('click', whoWasClicked);
#lowerElement {
background-color: rgb(128, 128, 128);
min-width: 25vw;
height: 100px;
text-align: center;
position: absolute;
top: 37vh;
left: 37vw;
z-index: 1;
}
#upperElement {
min-width: 25vw;
height: 100px;
text-align: center;
line-height: 50px;
position: absolute;
top: 37vh;
left: 37vw;
z-index: 2;
pointer-events: none;
}
<div id="lowerElement">Click Me</div>
<div id="upperElement">Overlay</div>

With my current code, I think the z-index: -1; in #about is the problem: #blue_border is an image background and it's upper my "about" div... So I'm trying to find a way to replace that background.
Edit:
Okay. I figured out that the element with z-index: -1; will never be clickable the way I want to.
So I decided to reverse everything: the logo has now the property z-index: -1; and the about div (which is upper now) is hidden until the hover trigger. I also changed my background image by a border.
My code now :
/*Under #about and visible*/
#logo {
z-index: -1;
}
.blue_border {
width: 600px;
height: 600px;
border: 15px solid #71d1f4;
border-radius: 100%;
/*background-image: url("./border.png");
background-repeat: no-repeat;*/
background-position: 50%;
}
/*Hidden first*/
#about {
opacity: 0;
visibility: hidden;
position: relative;
margin-top: -605px;
width: 600px;
height: 600px;
border-radius: 100%;
background-color: #25B8EE;
-webkit-transition: opacity 600ms, visibility 600ms;
-o-transition: opacity 600ms, visibility 600ms;
-moz-transition: opacity 600ms, visibility 600ms;
transition: opacity 600ms, visibility 600ms;
}
/*Unhidden on hover*/
.blue_border:hover #about
{
opacity: 1;
visibility: visible;
}
I didn't changed my html
Thanks anyway guys. It was my very first question and I'm glad that some of you already answered me !

transform: scale(n); - different on mousein than on mouseout

I am using transform: scale(); on a website. I hope somebody can help me with a question I could not resolve by searching in the web.
Here is my code:
HTML:
<div class="hopp_circle_img">
<img src="..." alt="" />
</div>
CSS:
.hopp_circle_img {
position: relative;
width: 100% !important;
height: 100% !important;
max-width: 100% !important;
max-height: 100% !important;
overflow: hidden;
-webkit-border-radius: 50%;
border-radius: 50%;
z-index: 0;
}
.hopp_circle_img img {
-webkit-transition: transform 0.15s;
transition: transform 0.15s;
}
.hopp_circle_img img:hover {
display: block;
z-index: 100;
-webkit-transform: scale(1.25);
transform: scale(1.25);
}
That works fine, but I was asked to make the effect different when the courser moves in, than when it moves out. E.g. to scale fast on mouse-in, but slow on mouse-out. Is there any solution for that either in CSS3 or in Javascript?
Thank you
rabox

Set a the slow transition to the element (.hopp_circle_img img), and the fast transition to the element while it's hovered (.hopp_circle_img img:hover). So when you leave the element, the slower transition will be in effect.
I've set the transition shorthand property with different duration and easing, but you can just change transition-duration or set transition-delay or a different transition-timing-function (easing).
.hopp_circle_img {
position: relative;
width: 100% !important;
height: 100% !important;
max-width: 100% !important;
max-height: 100% !important;
overflow: hidden;
-webkit-border-radius: 50%;
border-radius: 50%;
z-index: 0;
}
.hopp_circle_img img {
-webkit-transition: transform 0.5s ease-out;
transition: transform 0.5s ease-out;
}
.hopp_circle_img img:hover {
display: block;
z-index: 100;
-webkit-transform: scale(1.25);
transform: scale(1.25);
-webkit-transition: transform 0.15s;
transition: transform 0.15s;
}
<div class="hopp_circle_img">
<img src="https://65.media.tumblr.com/avatar_39c12973e9fe_128.png" alt="" />
</div>

Sorry, directly after posting I resolved the topic on my own. There has to be a different transition-time on :hover. e.g.
.hopp_circle_img img {
-webkit-transition: transform 0.15s;
transition: transform 0.15s;
}
.hopp_circle_img img:hover {
display: block;
z-index: 100;
-webkit-transform: scale(1.25);
transform: scale(1.25);
-webkit-transition: transform 2s;
transition: transform 2s;
}
}

Move div when hovering another div with jquery

When I hover a div at the bottom, which only is shown a little bit, (div has width:100%;), I want this div to move up with a mouseovereffect, and the same time push the logo, which is in the center of the screen, upwards. I want to use jQuery, because nothing else works. When the mouse is off the div, I want the div to fall back down to hiding. They are two div's inside the body.
Here is parts of the html and css: code
I hope someone knows how to make a javascript to make this hover function where hovering a div moves another div, then goes back to normal.

Does this help
using the jquery animate you can animate the movement of divs easily..
<div id="box1"></div>
<div id="box2"></div>
<style type="text/css">
#box1
{
width: 100px;
height: 100px;
background-color: red;
}
#box2
{
width: 100px;
height: 100px;
background-color: yellow;
margin-top: 10px;
}
</style>
<script type="text/javascript">
$("#box1").hover(function(){
//alert("hover");
$("#box2").animate({marginLeft: "200"});
});
$("#box1").mouseleave(function(){
$("#box2").animate({marginLeft: "0"});
});
</script>

There are few changes which need to be made in your code,
1) You have given class boks1 in jquery , but such class does not exist in your code.
2)you can combine both mouseover and mouseout in hover function itself.
Jquery
$(document).ready(function () {
$(".box1").hover(function () { // on hover
$(".box").css("margin-top", "-20px");
},function() {//on mouseout
$(".box").css("margin-top", "20px");
});
});

Something like this should work (if I understand your question).
I only changed the jQuery and one line of the CSS (the last line in .box was changed to transition: background 0.4s 0.5s, margin 0.4s;).
$(document).ready(function () {
$(".textarea").hover(
function () {
$(this).height($(this).height() + 200);
$(".box").css("margin-top", "-200px");
},
function () {
$(this).height($(this).height() - 200);
$(".box").css("margin-top", "");
}
);
});

});
see Fiddle
For your information: Your code did not work because of typo in your jQuery selectors. I also mentions that you are using float left a certain time that makes no sense because you overrule it with other styles.
I'm animating the top position because the margin will not do the right thing. When using margin the animation stops when there is no space.
I'm trigger the hover on the texarea becaus it covers the hole width. When using the .box itselfe then you will loose the focus during the hover effect. This will end up in a jumping effect.
I also us the stop function to clear the quehe otherwhise every hover event will be stored an triggerd (makes also an jumping effect)
So my snippet may give you an idea of how to achieve your needs.
