Custom css doesn't apply properly to my site

Hi 🙂
I made a custom css for image swap on hover like this video: https://youtu.be/7WC906n4t5c.

Here is the code I used 

.image-swap img:nth-child(1) {
  position: absolute;
  transition: .5s;
}

.image-swap img:nth-child(1):hover {
  opacity:0;
}

 

In the edit page it's looking great! But in my website the top image is bigger then the bottom image (https://talshait.com/work/color).

Here is my video screenshot: https://youtu.be/Hvf7Re0VGKQ

 

I would appreciate any help

Try adding to Home > Design > Custom Css

.image-swap {
  position: relative;
}

Let me know how it works on your site
