Hover zoom-in CSS

Hello,

​

I am trying to get a zoom-in effect on hover for my images inside a gallery.

However, the center image is always showing a weird scaling or margin issue that I cannot get rid of.

The issue is more visible in the middle image inside my 3-columns-galleries.

The issue is more or less visible depending on the width of the browser window.

​

Attached is a small GIF showing the issue.

The margin is not respected and behaving weirdly

​

This is the example page from my website :

​

Here is my current CSS code :

`.wp-block-gallery .wp-block-image {`

`overflow: hidden;`

`}`

`.wp-block-gallery .wp-block-image img {`

`transform: scale(1);`

`transition: .3s ease-in-out;`

`}`

`.wp-block-gallery .wp-block-image:hover img {`

`transform: scale(1.03);`

`}`

​

I have tweaked the CSS without success and I cannot understand why only the middle image is behaving like this.

FYI my images have a .5px margin.

​

Thank you for you support !

Have a nice day 🙂
