Question posted in 
Explanation
I’m trying to set a overlay on each image of the slider (slick.js) when hovering them, but for some reason, when I hover it, the overlay appears on top of the slider (all 12 images), not the image hovered.
Code
You can also see it in JSFiddle and in “fullscreen mode”.
ps: it’s be better to see the overlay content in fullscreen.
$('.carousel').slick({
arrows: false,
dots: true,
slidesPerRow: 3,
rows: 3
});.carousel-wrapper {
background-color: rgb(235, 235, 235);
position: relative;
}
img {
background-color: black;
}
.slick-slide {
text-align: center !important;
}
.overlay {
position: absolute;
height: 100%;
width: 100%;
top: 0;
left: 0;
background: rgba(1, 1, 1, .35);
transition: 0.2s;
opacity: 0;
}
.overlay:hover {
opacity: 1;
}
.overlay-content {
color: rgb(255, 255, 255);
position: absolute;
top: 50%;
left: 50%;

Why is it not working?
Your code doesn’t work as expected because your overlay is being positioned relatively to
.carousel-wrappernot theaelement (.carousel-wrapperis the first parent of.overlaythat haspositionother thanstatic– if you don’t set yourpositionexplicitly it defaults tostatic).How to avoid this mistake in the future?
If you want any element on your website to have an overlay (or in general you want to use
position: absolutesomewhere) you need to remember that this element is going to be positioned relatively to it’s parent that haspositon: relativeorposition: absolute. If there’s no such element it’s going to position itself to<html>.It’s very well explained here:
(on absolute positioning)

Check the working demo:
https://jsfiddle.net/thffcgqc/2/
Wrap your anchor tags and overlay content in a separate div and style as follows. The reason is due to the fact that you are not using a margin-right for whitespace between boxes. You are simply using a fixed with
litags and the images leaves a gap in the parent container . If an overlay is placed, you will see the overlay over the white gap and the image (which is somewhat not what you want – I believe)See snippet below
