Target This and Class not working as expected

For some reason, as you can see in my pen, when I hover over a learn more button it adds the details class to all the cards.
I've tried with no luck :
$(this).find('element')
And :
('', this)
//slick slider
$('.responsive').slick({
dots: true,
prevArrow: $('.prev'),
nextArrow: $('.next'),
infinite: false,
speed: 300,
slidesToShow: 4,
slidesToScroll: 4,
responsive: [{
breakpoint: 1024,
settings: {
slidesToShow: 3,
slidesToScroll: 3,
infinite: true,
dots: true
}
},
{
breakpoint: 600,
settings: {
slidesToShow: 2,
slidesToScroll: 2
}
},
{
breakpoint: 480,
settings: {
slidesToShow: 1,
slidesToScroll: 1
}
}
// You can unslick at a given breakpoint now by adding:
// settings: "unslick"
// instead of a settings object
]
});
//tilt
$('.tilt-card').tilt({
perspective: 1000,
})
//show details
$(".faction-more-btn").hover(
function() {
$('.description-overlay').addClass('desc-hover');
},
function() {
$(".description-overlay").removeClass('desc-hover');
}
);
$(document).ready(function() {
$('button').hover(function() {
$(this).text('Read More');
}, function() {
$(this).text('Learn More');
});
});
//scroll text
$(document).ready(function() {
var count;
var interval;
$(".faction-more-btn").on('mouseover', function() {
var div = $('.description-container');
interval = setInterval(function() {
count = count || 1;
var pos = div.scrollTop();
div.scrollTop(pos + count);
}, 100);
}).click(function() {
if (count < 6) {
count = count + 1;
}
}).on('mouseout', function() {
// reset the speed on out
count = 0;
clearInterval(interval);
$(".description-container").scrollTop(0);
});
});

Live version on codepen

is this what you are looking for:
$(this).closest('.tilt-card').find('.description-overlay').addClass('desc-hover');
instead of
$('.description-overlay').addClass('desc-hover');
https://codepen.io/anon/pen/zJaPbQ
Your problem is that you are adding class to all elements with css class 'description-overlay', you have to add only to the one inside current tilt-card

Working codepen.
That happens because of the hover part bellow, you're using class selector $('.description-overlay') that will select all the elements with this class and add/remove class desc-hover.
$(".faction-more-btn").hover(
function() {
$('.description-overlay').addClass('desc-hover');
},
function() {
$(".description-overlay").removeClass('desc-hover');
}
);
Should use $(this) to target the related .description-overlay div of every button :
//show details
$(".faction-more-btn").hover(
function() {
$(this).siblings(".description-overlay").addClass('desc-hover');
},
function() {
$(this).siblings(".description-overlay").removeClass('desc-hover');
}
);
NOTE : Both functions you've tried doesn't work since they look inside the current hovered button when the div is a sibling of the button, so you could use siblings() function or the combination of parent()/closest() method and find() like :
$(this).parent().find(".description-overlay");
$(this).closest('.tilt-card').find(".description-overlay");
$(this).siblings(".description-overlay")

CSS, express and bootstrap : overflow and margin error

I stack two circles over an image, using the position and overflow properties.
It works fine but I have the circle running over the image on left and right (not top and left.
Here is the image : Circle overflowing
Here is the CSS.
.mainContainer {
background-color: #A6A4AA
}
.targetImage {
margin: 0;
width: 100%;
height: auto;
border: solid medium #2C3756;
border-radius: 0 0 8px 8px;
background-color: #A6A4AA;
position: relative;
}
#targetCol {
overflow: hidden;
position: absolute;
}
.impact, .ajustement {
position: absolute;
background-color: #dc022e;
border-radius: 100%;
opacity: 0.75;
margin: 0;
width: 100%;
height: auto;
border: solid medium #2C3756;
}
.ajustement {
opacity: 0.5;
}
The code source (ejs+bootstrap) : the row is a child of mainContainer
<div class="row"> <!-- Row : target -->
<div class= "col-xs-12" id="targetCol">
<img id="target" class="targetImage"></img>
<div id="ajustement" class="ajustement"></div>
<div id="impact" class="impact"></div>
</div>
</div>
How can I draw my circles into the images only, without running out the border ?
Here is what I would like :

Do you looking something like this:
body{
margin: 0;
background-color: #A6A4AA
}
.mainContainer {
background-color: #A6A4AA;

border-radius: 0 0 8px 8px;
background: #A6A4AA;
position: relative;
}
#targetCol {
overflow: hidden;
position: absolute;
border: 3px solid #2C3756;
line-height: 0;
border-radius: 12px;
}
.impact, .ajustement {

Fit 4 divs inside each 2 divs which are aligned left and right

I'm developing a little application using Angular 2 for somebody whose doing an experiment, and so I'm trying to fit 4 divs, each containing an image, into each 2 divs.
For some reason, all the divs (containing the images) are aligned one above the other, instead of one next to each other and only going down one row in case of wrapping. I'm expecting the guesser and describer divs to fit in the designated area: guesser left of the vertical divider and describer right to the vertical divider, and both above the horizontal divider, but they don't seem to fill the width of the area, and overflow vertically past the horizontal divider.
How the website currently looks
What I'm expecting the website to look (I edited this using Paint, it's just for illustration)
And this is my component's HTML and CSS:

}
div.describer div.container {

div.describer div.container img.blocked {

}
div.describer div.container img.target {

I searched for solutions on Stack Overflow and tried implementing what I found but for some reason it didn't help.

If you want the elements side by side, you should use style "display: inline-block".
And you can try wrap the content with a div and put a border layout at bottom like this:
UPDATE
Wrap the containers in a div with style display: grid; grid-template-columns: 50% 50%;

Toggle Class while removing class from siblings

I have a map where I am toggling a class when you click on a dot/location that pops up a tooltip. The issue I'm running into is that when I click on another dot the other siblings tooltips are not going away. I tried to solve this by removing the class of the siblings on click, but when I do this the toggle stops working and I cannot click the dot again to get rid of the active tooltip.
I need the toggle on the currently active tooltip to still work but I also need the sibling tooltips to disappear as well.
I hope I explained that right. Here is a codepen: http://codepen.io/anon/pen/BzQrLV
$('.dot').click(function() {
$('div.toggle-active').removeClass('toggle-active');
$(this).next().toggleClass('toggle-active');

Add .not($(this).next()) to your removeClass statement so you don't remove the active class from all the dots, just the dots not being clicked on.
$('.dot').click(function() {
$('div.toggle-active').not($(this).next()).removeClass('toggle-active');
$(this).next().toggleClass('toggle-active');
});

Updated to check whether the tooltip was already being displayed before displaying it.
$('.dot').click(function() {
var displayed = $(this).next().attr('class').match('toggle-active');
$('div.toggle-active').removeClass('toggle-active');
if(!displayed){
$(this).next().toggleClass('toggle-active');
}

Uncaught ReferenceError: slide is not defined

I'm trying to make the left arrow in my page change the background color of the container on click, but whenever I click it I get this error: (index):147 Uncaught ReferenceError: slide is not defined I've tried every solution available here and still no luck. Here's the jsfiddle: https://jsfiddle.net/mLr6oax0/

I would do the following:
use element.style.backgroundColor instead of your intended element.setAttribute('style', 'background-color: 'orange')
use of addEventListener with id or class hooks over HTML's onclick
Test the solution below:
var container = document.getElementById("container");
var clickable = document.getElementById('clickable');
clickable.addEventListener('click', function () {
container.style.backgroundColor = 'orange';
});
