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 fadeInTooltip {

opacity: 0;
}
to {
opacity: 1;
}
}
#keyframes fadeOutTooltip {

}
}
<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");
});

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.

How can i change my css overflow depending on the content?

I'm making my own dropdown with CSS. You hover on it, then some options appear below it, you pick one and that's it. If there are too many options to fit there is a scroll bar. You can see the whole thing here: JSFiddle
let testData = [
"qwertyuiop",
"asdfghjkl",
"zxcvbnm",
"axdxfcbhdhvhv",
"äöäööäöääöää",
"zoinkszoinks",
"brrrrrrrrrr",
"gygygygyasdasda",
];
getTestStuff();
function getTestStuff() {
let content = document.getElementById("content");
let text = document.getElementById("text");
for (let group of testData) {
let div = document.createElement("div");
div.innerHTML = group;
div.addEventListener("click", function() {
text.innerHTML = group; // update button text
}, false);
content.appendChild(div);
}
}
let dropdown = document.getElementById("dropdown");
let arrow = document.getElementById("arrow");
let content = document.getElementById("content");
dropdown.addEventListener("mouseenter", function () {
arrow.className = "open";
content.classList.add("open");
}, false);
dropdown.addEventListener("mouseleave", function () {
arrow.className = "closed";
content.classList.remove("open");
}, false);

</div>
</div>
The Problem:
The scrollbar appears during my animation. Which is not a problem, if it is going to stay, but when the content fits, it disappears again.
When the scroll bar is not there, the space that the scrollbar would take, does not have the right background color, when i hover over the option. Making a very ugly gap.
I know about overflow: auto; but i still use overflow: scroll; with margin-right: -16px; on the children, because my scrollbar moves the children and i only have that scrollbar sometimes.
I need some kind of CSS conditional hack to set overflow to hidden if we don't need it or use JS to change the margin-right but trying to check the parent height after adding the kids gave me this:
content.height: undefined
content.style.height: empty string
So i'm very lost with this.

I got it working with this trick on the children:
margin-right: calc(100% - 300px);
And setting the parent overflow to auto
This works because here 100% is the elements full width. Without a scroll bar, 100% is 300px, so margin is set to 0. With a scroll bar, 100% is around 290px so margin is set to around -10, so the text stays centered.

As #CBroe pointed out, i couldn't get the height of my element, or the children because it had display: none so to get around that:
let content = document.getElementById("content");
content.style.display = "block";
let height = content.offsetHeight;
content.style.display = "";
It's amazing something this dumb works so well. Now i can hide the scrollbar when i don't need it and fix the offset, that the scrollbar creates, when i do need it:
if (height < 300) {
content.style.overflowY = "hidden";
} else {
content.style.overflowY = "scroll";
for (let kid of content.children) {
kid.style.marginRight = "-16px";
}
}
This solution has the added bonus, that it works well with my animation. A problem that the CSS only solution couldn't solve.

how to show text when hover over an image

how do I make a text like this show up once I hover over an image? some tumblr themes have this same feature too so i wonder how do you do it heres an example of what I mean

you can try this
.container{
width:200px;
height:200px;
text-align:center;
display:flex;
justify-content:center;
align-items:center;
position: relative;
}
.hide {
display: none;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
img{
width:200px;
height:200px;
}
img:hover + .hide {
display: block;
}
.hide:hover{
animation: color-change 1s infinite;
}
#keyframes color-change {
0% { color: orange; }
50% { color: green; }
75% { color: yellow; }
100% { color: lightblue; }
}
<div class="container">
<img src="https://i.imgur.com/W0cq73T.jpg">
<div class="hide">this text will be shown when someone hovers the image</div>
</div>
so basically you set the text to display:none to hide the text.
And set it to display:block to show the text when someone hovers it, javascript is not needed at all
and now you can use the animation to animate the color of the text like in the video when someone hovers the text

let test = document.getElementById("test");
test.addEventListener("mouseover", function(event) {
// highlight the mouseover target
event.target.style.color = "orange";
// reset the color after a short delay
setTimeout(function() {
event.target.style.color = "";
}, 500);
}, false);
#center {
display: flex;
justify-content: center;
align-items: center;
height: 300px;
width: 300px;
background: url('https://www.iso.org/files/live/sites/isoorg/files/news/News_archive/2017/08/Ref2213/Ref2213.jpg/thumbnails/300x300');
color: #fff
}
<div id="center">
<p>Te<span id="test">ss</span>s</p>
</div>

Stuck on trying to replicate a certain CSS-Transition (CTA-Button that moves to the bottom corner of the page when scrolling down and gets fixed)

So here is a simple fiddle (http://jsfiddle.net/t1xywroc/2/) I created to show you the animation I'm trying to replicate (from this website: https://paperpillar.com/).
I'm still fairly new to Javascript/Jquery and have only been doing HTML and CSS for a couple months.
The problem about my animation is that (as far I know) there is no transition from an absolute position to a fixed position, which I believe causes that small jump, right after triggering the animation (or transition if you will). The second problem is, that the content of the ::before element can't be transitioned either. How can I fix these things using jQuery?
I tried to get it work by using mostly CSS but I keep coming across new problems. I guess it's inevitable to use JavaScript, which is what I need help with. I'd really appreciate it.
Note: not a native speaker.

}
JS
$(document).ready(function() {
$(window).on('scroll', function() {
if ($(window).width() <= 768) {
var scrollTop = $(this).scrollTop();
$('.button').each(function() {
var topDistance = $(this).offset().top;
if ((topDistance - 30) < scrollTop) {
$(this).addClass('floating');
// Haven't put much thought into this part yet
} else if ((topDistance - 30) >= scrollTop){
}
});
}
});
});

A couple of problems have been highlighted in the question: the 'jump' when the transition moves between absolute and fixed and the fact that pseudo elements' content can not be transitioned.
To get round the absolute to fixed jump problem we can set the button to fixed as soon as the transition is to start and then transition. This is possible by introducing CSS animations rather than transitions.
To appear to transition between content we use before pseudo element to hold the initial text (as in the code given) and introduce an after pseudo element that holds the svg. To give the appearance of transitioning between the two we animate opacity.
Note: in the website which is to be emulated the button initially has a white background over the page's white background. This means the change in shape as the initial button fades away is less obvious. With a contrasting blue background the change in shape is much more obvious. That may or may not be the effect required.
Here's a snippet with animations instead of transitions and moving to fixed immediately the animation starts.
$(document).ready(function() {
$(window).on('scroll', function() {
if ($(window).width() <= 2500) {
var scrollTop = $(this).scrollTop();
$('.button').each(function() {
var topDistance = $(this).offset().top;
if ((topDistance - 30) < scrollTop) {
$(this).addClass('floating');
} else if ((topDistance - 100) >= scrollTop){
}
});
}
});

half borders at top right corner and bottom left corner with css

I have a few images where I'd like half borders to the top right corner and to the bottom left corner. The problems I am running into are:
problem 1: I have managed to cut of borders at all four corners, but can't cut of top left and bottom right. code below (I'm using this fiddle provided by KillaCam, and experimented a little, with the result that all four corners appear at first and then three of them disappears! : http://jsfiddle.net/3jo5btxd/
#div1 {
position: relative;
height: 100px;
width: 100px;
background-color: white;
border: 1px solid transparent;transition: border 2000ms ease 0s;
}
#div2 {
position: absolute;
top: -2px;
left: -2px;
height: 84px;
width: 84px;
background-color: #FFF;
border-radius: 15px;
padding: 10px;
}
Problem 2 I already have a panel that has a link vertically centered using the css table method, which is also visible on hover. When I combine the panel's code with the corner borders, my vertical centering goes out of whack! I guess that is happening because of the extra div I am using for borders, but I haven't managed to make the corners with :before (doesn't work on hover). HTML and css below and the also the image showing what I want to make:
<ul class="img-list">
<li class="category_lists one-third column-block" '="">
<a href="http://kohphangan.smartsolutionpro.us/category/adventure/">

And the image showing what I want to make: http://tinypic.com/r/2gy5zk4/8 .
If I have to use javascript, I will, but I am not very good at it, so counting on css to make it work. Thanks a lot for any help.

Here's one solution: http://jsfiddle.net/f7u6yxLq/.
HTML:
<div></div>
CSS:
* {
margin: 0;
padding: 0;
}
body {
padding: 10px;
}
div {
position: relative;
display: table;
width: 200px;
height: 100px;
background: url("http://placehold.it/200x100")
no-repeat
top left;
}
div:before,
div:after {
content: "";
position: absolute;
width: 50px;
height: 50px;
border: solid white;
border-width: 2px 2px 0 0;
display: none;
}
div:before {
right: 5px;
top: 5px;
}
div:after {
border-width: 0 0 2px 2px;
bottom: 5px;
left: 5px;
}
div:hover:after,
div:hover:before {
display: block;
}

Solution for problem #1: http://jsfiddle.net/3jo5btxd/2/
.div2:before, .div2:after {width:9px; height:9px; position: absolute;background:#fff; content:'';}
.div2:before {top:0; left:0;}
.div2:after {bottom:0; right:0; }
