Make hovered tooltip disappear when clicking button

I am trying to create a tooltip for whatever that needs it on my website, e.g. a button, text, etc. So far I have something like this:
https://jsfiddle.net/f06q3cLg/
.content {
display: grid;
width: 100vw;
height: 100vh;
place-content: center;
}
.content .parent {
border: 1px red solid;
padding: 10px;
position: relative;
}
.content .parent:hover .tooltip-wrapper {
animation: 0.1s fadeInTooltip;
animation-fill-mode: forwards;
animation-delay: 0.4s;
}
.content .parent:hover:before {
animation: 0.1s fadeInTooltip;
animation-fill-mode: forwards;
animation-delay: 0.4s;
}
.content .parent:active .tooltip-wrapper {
animation: 0.05s fadeOutTooltip;
animation-fill-mode: forwards;
}
.content .parent:active:before {
animation: 0.05s fadeOutTooltip;
animation-fill-mode: forwards;
}
.content .parent:before {
content: "";
display: block;
width: 0;
height: 0;
position: absolute;
border-left: 6px solid transparent;
border-right: 6px solid transparent;
left: 50%;
transform: translateX(-50%);
opacity: 0;
}
.content .parent .tooltip-wrapper {
position: absolute;
display: grid;
left: 0;
width: 300px;
height: 100%;
opacity: 0;
pointer-events: none;
}
.content .parent .tooltip-wrapper.bottom {
top: calc(100% + 8px);
}
.content .parent .tooltip-wrapper .tooltip {
max-width: 300px;
width: fit-content;
padding: 8px;
position: absolute;
display: inline-block;
background: blue;
border-radius: 5px;
padding: 8px;
color: white;
font-size: 11px;
box-shadow: 0px 3px 3px rgba(0, 0, 0, 0.2);
line-height: 1.3;
text-align: left;
}
/* Keyframes */
#keyframes fadeInTooltip {
from {
opacity: 0;
}
to {
opacity: 1;
}
}
#keyframes fadeOutTooltip {
from {
opacity: 1;
}
to {
opacity: 0;
}
}
<div class="content">
<div class="parent">
Hover me
<div class="tooltip-wrapper">
<span class="tooltip">This is my tooltip</span>
</div>
</div>
</div>
As such, it works somewhat fine. My issue is that I would like the tooltip to disappear when I click the button. Now it vanishes, and then comes back with a 0.4s delay as the hover effect actually has. Ideally the tooltip should disappear as long as my mouse is still on the button, but when I remove it and re-enters the button, then the tooltip should re-appear.
I'm not sure if this is even achievable with pure CSS, but any JS would also do.

The problem is that :active is only applied as long as the mouse is down.
mdn: :active:
The :active CSS pseudo-class represents an element (such as a button) that is being activated by the user. When using a mouse, "activation" typically starts when the user presses down the primary mouse button.
What you could do (if you want to stay CSS only) is to use tabindex="0" on the <div class="parent"> and :focus instead of :active. But you need to verify that using tabindex="0" here won't hurt usability.
Ideally the tooltip should disappear as long as my mouse is still on the button, but when I remove it and re-enters the button, then the tooltip should re-appear.
That won't work with :focus either. I'm pretty sure that this behavior can only be achieved with JS. If it is possible with CSS only it likely would be a pretty hacky solution.
But from the perspective of a user, this seems to be counterintuitive that the tooltip won't appear after clicked.
A JavaScript solution that does what you want could look like this.
It is a simplified version of the tooltip to only show the relevant parts.
Every element having a tooltip has an attribute data-has-tooltip.
// event delegation for all mouse down event:
// this ensures that the code also works for elements that have been added to the DOM after that script was executed.
document.addEventListener('mousedown', (evt) => {
// check if the mousedown happened in an element with a tooltip
const element = evt.target.closest('[data-has-tooltip]');
if (element) {
// if the user already clicked on the element ignore the click
if (!element.classList.contains('active')) {
// add the active class to the element so that hover won't show the toolip
element.classList.add('active');
function removeActiveOnLeave() {
// remove the active class
element.classList.remove('active');
// remove the mouseleave event listener again
element.removeEventListener('mouseleave', removeActiveOnLeave)
}
// add an event listener for mouseleave to remove the active class
element.addEventListener('mouseleave', removeActiveOnLeave)
}
}
});
.parent {
display: inline-block;
border: 1px solid red;
padding: 0.5rem;
margin: 0.5rem;
}
.tooltip-wrapper {
display: none;
}
.parent:hover .tooltip-wrapper {
display: block;
}
.parent.active:hover .tooltip-wrapper {
display: none;
}
<div class="content">
<div class="parent" data-has-tooltip>
Hover me A
<div class="tooltip-wrapper">
<span class="tooltip">This is my tooltip A </span>
</div>
</div>
</div>
<div class="content">
<div class="parent" data-has-tooltip>
Hover me B
<div class="tooltip-wrapper">
<span class="tooltip">This is my tooltip B</span>
</div>
</div>
</div>

HTML
<div class="content">
<div class="parent" onClick="myFunction()">
Hover me
<div class="tooltip-wrapper">
<span class="tooltip" id="tooltip">This is mytooltip</span>
</div>
</div>
</div>
Javascript
function myFunction(){
var tooltip=document.getElementById("tooltip");
if (tooltip.style.display=="none") {
document.getElementById("tooltip").style.display="block";
} else {
document.getElementById("tooltip").style.display="none";
}
}

Manipulating 'display' property.
const parent = document.querySelector('.parent');
const toolTip = document.querySelector('.tooltip');
parent.addEventListener('click', () => {
if(toolTip.style.display !== 'none') {
toolTip.style.display = 'none';
}else {
toolTip.style.display = 'grid';
}
});

A solution using jQuery 3.4.1:
$(".parent").click(function () {
$(".tooltip-wrapper").css("display", "none");
});
The only downfall with that solution is once you click and re-hover in the same session, the SCSS :hover doesn't work properly.
No need to stress, just add the following if you want that functionality:
$(".parent").hover(function () {
$(".tooltip-wrapper").css("display", "block");
});
Try it out in the attached snippet:
$(".parent").click(function () {
$(".tooltip-wrapper").css("display", "none");
});
$(".parent").hover(function () {
$(".tooltip-wrapper").css("display", "block");
});
.content {
display: grid;
width: 100vw;
height: 100vh;
place-content: center;
}
.content .parent {
border: 1px red solid;
padding: 10px;

}
.content .parent:hover .tooltip-wrapper {
animation: 0.1s fadeInTooltip;

}
.content .parent:hover:before {

}
.content .parent:active .tooltip-wrapper {

<div class="content">
<div class="parent">

<div class="tooltip-wrapper">
<span class="tooltip">This is my tooltip</span>
</div>
</div>
</div>
OR, you can see it working in this Fiddle. with your initial
SCSS.
You can uncomment the second function to see the hover working again after clicking.

JQuery rotation forward and backward animation

I am trying to make plus to cross toggle button. Ive already created a transforming forward animation with transition but i cant figure out how to make slight transition to backwards. Thanks in advance!
Here is my code snippets.
<div class="tog-holder" id="tog"></div>
<div class="anim" id="anim">
<p>blabla</p>
</div>
.tog-holder{
position:relative;
width:32px;
height:32px;
padding:15px 0;
cursor: pointer;
border-radius: 50%;
background: url(https://rscua.com/wp-content/uploads/2020/05/plus_icon-icons.com_69322.png);
background-size: cover;
}
.animaterotate {
transform: rotate(45deg);
transition:all .2s ease-in-out;
}
jQuery(document).ready(function(){
jQuery(".anim").hide();
jQuery(".tog-holder").click(function(){
jQuery(this).toggleClass('animaterotate');
jQuery(this).next(".anim").slideToggle();
});
});
A snippit to work with:
jQuery(document).ready(function() {
jQuery(".anim").hide();
jQuery(".tog-holder").click(function() {
jQuery(this).toggleClass('animaterotate');
jQuery(this).next(".anim").slideToggle();
});
});
.tog-holder {
position: relative;
width: 32px;
height: 32px;
padding: 15px 0;
cursor: pointer;
border-radius: 50%;
background: url(https://rscua.com/wp-content/uploads/2020/05/plus_icon-icons.com_69322.png);
background-size: cover;
}
.animaterotate {
transform: rotate(45deg);
transition: all .2s ease-in-out;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="tog-holder" id="tog"></div>
<div class="anim" id="anim">
<p>blabla</p>
</div>

I made a small change on your css and jquery code.
Therefore, I used "hasClass" to check the state of the rotation without really using the 'animaterotate' for css directly.
NEW VERSION:
jQuery(document).ready(function() {
jQuery(".anim").hide();
jQuery(".tog-holder").click(function() {
if(!jQuery(this).hasClass('animaterotate'))
jQuery(this).css("transform", "rotate(45deg)");
else
jQuery(this).css("transform", "rotate(0deg)");
jQuery(this).toggleClass('animaterotate');
jQuery(this).next(".anim").slideToggle();
});
});
.tog-holder {
position: relative;
width: 32px;
height: 32px;
padding: 15px 0;
cursor: pointer;
border-radius: 50%;
background: url(https://rscua.com/wp-content/uploads/2020/05/plus_icon-icons.com_69322.png);
background-size: cover;
transition: all .2s ease-in-out;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="tog-holder" id="tog"></div>
<div class="anim" id="anim">
<p>blabla</p>
</div>
OLD VERSION:
jQuery(document).ready(function() {
jQuery(".anim").hide();
jQuery(".tog-holder").click(function() {
if(!jQuery(this).hasClass('animaterotate'))
{
jQuery(this).css("transform", "rotate(45deg)");
}
else
{
jQuery(this).css("transform", "rotate(0deg)");
}
jQuery(this).css("transition", "all .2s ease-in-out");
jQuery(this).toggleClass('animaterotate');
jQuery(this).next(".anim").slideToggle();
});
});
.tog-holder {
position: relative;
width: 32px;
height: 32px;
padding: 15px 0;
cursor: pointer;
border-radius: 50%;
background: url(https://rscua.com/wp-content/uploads/2020/05/plus_icon-icons.com_69322.png);
background-size: cover;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="tog-holder" id="tog"></div>
<div class="anim" id="anim">
<p>blabla</p>
</div>

I added another class while going back.
jQuery(".anim").hide();
jQuery(".tog-holder").click(function(){
jQuery(this).toggleClass('animaterotate');
if(!jQuery(this).hasClass('animaterotate')) {
jQuery(this).addClass('animaterotate2');
}
else {
jQuery(this).removeClass('animaterotate2');
}
jQuery(this).next(".anim").slideToggle('2000');
});
.animaterotate2 {
transform: rotate(0deg);
transition:all .2s ease-in-out;
}

Add CSS Transition between image switch

In my site I have a switch between a down arrow & and an up arrow. See here
How do I change this to a CSS transition, so there's a brief break between the switch?
Here's my code:
function close_accordion_section(source) {
$(source).parent().find('.accordion-section-title').removeClass('active');
$(source).parent().find('.accordion-section-content').slideUp(300).removeClass('open');
}
$('.accordion-section-title').click(function (e) {
if ($(e.target).is('.active')) {
close_accordion_section(e.target);
} else {
$(this).addClass('active');
$(e.target).parent().find('.accordion-section-content').slideDown(300).addClass('open')
}
e.preventDefault();
});
.accordion {
overflow: hidden;
margin-bottom: 40px;
}
.accordion-section {
padding: 15px;
border: 1px solid #d8d8d8;
background: #fbfbfb;
}
.accordion-section-title {
width: 100%;
display: inline-block;
background-image: url("https://cdn3.iconfinder.com/data/icons/google-material-design-icons/48/ic_keyboard_arrow_up_48px-512.png");
background-size: 5% 100%;
background-repeat: no-repeat;
background-position: top right;
}
.accordion-section-title.active {
background: url("https://cdn3.iconfinder.com/data/icons/google-material-design-icons/48/ic_keyboard_arrow_down_48px-128.png") top right no-repeat;
background-size: 5% 100%;
background-repeat: no-repeat;
}
.accordion-section-title.active, .accordion-section-title:hover {
text-decoration: none;
transition: color 0.1s linear;
}
.accordion-section-content {
padding: 15px 0;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="accordion">
<div class="accordion-section"> <a class="accordion-section-title" href="#accordion-1">More information</a>
<div id="accordion-1" class="accordion-section-content">
<p>Text.</p>
<p>
</div>
</div>
</div>

You can do this in 2 ways that I can think of. One is by jQuery-UI and add a
.delay(2000)
to the end of your transition. The other way is in your css class for your transition is do a
transition-delay: 2s;
For the arrow, it would be better to transition and rotate the image.
.rotate{
-ms-transform: rotate(180deg); /* IE 9 */
-webkit-transform: rotate(180deg); /* Chrome, Safari, Opera */
transform: rotate(180deg);
}
Here is a neat website to help you with that: http://www.css3maker.com/css3-transition.html

Hiding a text when a sections width is set to 0

so I've had a bit of a problem with trying to make a section's width to 0 and have everything inside the object do the same thing. Essentially hide the section and everything inside it. Thing is, the section will change to a width of 0px but the text inside still displays and also sort of pushes off to the side. Is there any way that I can use either css or javascript to hide the text and bring it back when the sections width changes back over?
Code pasted into jsfiddle:
http://jsfiddle.net/t6ck9ajb/
$(document).ready(function(){
$("#about").click(function(){
if ($("#about-me").css("width") <= "0vw") {
$("#introduction").animate({width:"0vw"}, 500);
/*$("#intro").css("display","none");
$("#port").css("display","none");
$("#about").css("display","none"); */
}
else {
$("#introduction").animate({width:"0vw"});
}
});
});
This is what I have to attempt at hiding the text, but this didn't really hide it.

Here is a different approach:
$(function(){
$('#about').on('click', homeAboutToggle);
$('#home').on('click', homeAboutToggle);
});
function homeAboutToggle(){
$('#introduction').toggleClass('active');
$('#about-me').toggleClass('active');
}
* {
margin: 0px 0px;
padding: 0px 0px;
font-family: "Open Sans";
}
#container{
width: 100vw;
height: 100vh;
overflow:hidden;
position:relative;
}
.full-page {
width: 100vw;
height: 100vh;
background-color: #5085aa;
position: absolute;
float: left;
transition:all ease-in-out 400ms;
-webkit-transition:all ease-in-out 400ms;
}
.full-page.right{
transform: translateX(100vw);
-webkit-transform: translateX(100vw);
}
.full-page.left{
transform: translateX(-100vw);
-webkit-transform: translateX(-100vw);
}
.full-page.active{
transition:all ease-in-out 400ms;
-webkit-transition:all ease-in-out 400ms;
transform: translateX(0);
-webkit-transform: translateX(0);
}
#introduction {
z-index: 1;
}
#about-me {
z-index: 0;
}
#information {
text-align: center;
}
#intro {
font-size: 4vw;
color: white;
text-align: center;
padding-top: 30vh;
}
#port{
position: absolute;
right: 3vw;
bottom: 5vh;
color: white;
font-size: 1.5vw;
text-decoration: none;
font-weight: bold;
}
#home,
#about{
position: absolute;
left: 3vw;
bottom: 5vh;
color: white;
font-size: 1.5vw;
text-decoration: none;
font-weight: bold;
}
#about:active #about-me {
width: 100vw;
}
.big {
font-size: 8vw;
color: lightblue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div id="container">
<section class="full-page right" id="about-me">
<h1 id="information">About Me</h1>
<a id="home">Back home</a>
</section>
<section class="full-page left active" id="introduction">
<h1 id="intro">Hello, my name is<br/><span class="big">Michael!</span> </h1>
<a id="port">Portfolio</a>
<a id="about">About Me</a>
</section>
</div>
</body>

If you're wanting to hide the content when the '#about' selector is clicked, why not just use $('#introduction').toggle()?

This a CSS issue. You need to add overflow: hidden; to whatever you want to be hidden with a change of width, in this case #intro.

Here a working fiddle with the intended animation: fiddle
CSS:
#introduction {
z-index: 1;
visibility:"visible";
overflow:hidden;
}
jQuery
$(document).ready(function () {
$("#about").click(function () {
if ($("#about-me").css("width") <= "0px") {
$("#introduction").animate({
width: "0px"
}, 500, function () {
$("#introduction").css("visibility", "hidden");
})
} else {
$("#introduction").animate({
width: "0px"
});
}
});
});

Why is jquery only registering a click once?

I know it's got to be a stupid simple problem, but it's been holding my back for too long...
I want to click the menu icon (picture) in the top right corner and have it display a transparent div menu over the entire screen. Then when I click the icon again, I want it to disappear.
JQuery is supposed to be hiding and showing a div on each click of the button. It shows the div the first time but after that, it doesn't register the click. I'm using transparent divs quite a lot on this project so my first guess is that something loads that is covering the button and that is stopping the click from "reaching" the button in question. But I've set a z-index to the button so it appears above everything else (also corroborated by the background color property) and yet when I click the button a second time, the div that it is supposed to hide stays there.
Here's my JQuery code:
$("#menuButton").click(function(){
if($("#menuOverlay").hasClass("displayIt")){
$("#menuOverlay").fadeOut(400);
} else {
$("#menuOverlay").fadeIn(400);
}
});
And here's my HTML:
<link rel="stylesheet" href="css/reset.css">
<link rel="stylesheet" href="css/styles.css">
</head>
<body>
<div id="container">
<header>
<p class="homeLink">Company Name Here</p>
<div id="menuButton"><img class="menuIcon" src="images/menuIcon.png"/></div>
</header>
<div class="slider">
<div class="sliderPic"></div>
<div class="sliderText"><p>This is come content just chilling right here.</p></div>
</div>
</div>
<footer>
<div id="arrowJumper"><img class="arrowIcon" src="images/greyArrow.png"/></div>
</footer>
<div id="menuOverlay" class="menuDiv">
<ul id="menu">
<li>Work.</li>
<li>About.</li>
<li>Careers.</li>
<li>Ideas.</li>
<li>News.</li>
<li>Events.</li>

And here's a fiddle for convenience: http://jsfiddle.net/yv9mr/
I'm pretty new at all of this so I really appreciate your assistance. I'm sure it's something simple. Thanks all!

You need to add/remove class on each click like this in your if-else block
if($("#menuOverlay").hasClass("displayIt")){
$("#menuOverlay").fadeOut(400);
$("#menuOverlay").removeClass("displayIt"); //remove class
} else {
$("#menuOverlay").fadeIn(400);
$("#menuOverlay").addClass("displayIt"); //add class
}
But the simplest way would be to fadeToggle the required div , in order to hide/show:
$("#menuOverlay").fadeToggle();

I suggest you use jQuerys .fadeToggle() method. In my opinion cleaner to let jQuery manage the toggle effect:
$("#menuButton").click(function(){
$("#menuOverlay").fadeToggle(400);
});
Tested and works with your example: JSFiddle.

Try this:
var clicked = false;
$("#menuButton").click(function(){
if (clicked == true){
$("#menuOverlay").fadeOut(400);
clicked = false;
} else {
$("#menuOverlay").fadeIn(400);
clicked = true;
}
});

The issue is that you are not adding or removing the class. Your event listener is working correctly, but you should add
$("#menuOverlay").toggleClass("displayIt");
to the end of your javascript (after the if/else).
A class such as "expanded" would be more semantic.

Reason Function is called again but your condition if($("#menuOverlay").hasClass("displayIt")) is always true so else never executes.. You can do
$("#menuButton").click(function(){
if($("#menuOverlay").hasClass("displayIt")){
$("#menuOverlay").removeClass("displayIt");
$("#menuOverlay").fadeOut(400);
} else {
$("#menuOverlay").addClass("displayIt");
$("#menuOverlay").fadeIn(400);
}
});
Fiddle
Or Simply
var shown=false;
$("#menuButton").click(function(){
if(!shown)
{
$("#menuOverlay").fadeOut(400);
shown =true;
}
else
{
$("#menuOverlay").fadeIn(400);
shown=false;
}
});
