rounded corner for project thumbnails when mouseover

[Thomas_blank]

I would like to know if there is any way to get rounded corner on project thumbnails when mouseover?

.thumb-rel{
    overflow: hidden;
    transition: all 200ms ease;
    border-radius: 0;
}

.thumbnail-wrap:hover .thumb-rel{
    border-radius: 30px;
}

Great! Thanks @arminunruh it works perfect 👌

Hey, my Thumbnails are already set to a rounded border, when I use the code above to ensure that they stay at that radius when hovering, there is still some glitching happening, showing the sharp (not rounded) edges between the hovering and not hovering state.
Is there a way to fix that?
