html - CSS Circular Cropping of Rectangle Image

Question

I want to make a centered circular image from rectangle photo. The photo's dimensions is unknown. Usually it's a rectangle form. I've tried a lot of methods:

Code

.image-cropper {
    max-width: 100px;
    height: auto;
    position: relative;
    overflow: hidden;
}

.image-cropper img{
    display: block;
    margin: 0 auto;
    height: auto;
    width: 150%; 
    margin: 0 0 0 -20%;
    -webkit-border-radius: 50%;
    -moz-border-radius: 50%;
    -ms-border-radius: 50%;
    -o-border-radius: 50%;
    border-radius: 50%;  
}

<div class="image-cropper">
   <img src="https://sf1.autojournal.fr/wp-content/uploads/autojournal/2012/07/4503003e3c38bc818d635f5a52330d.jpg" class="rounded" />
</div>

Answer 1

The approach is wrong, you need to apply the border-radius to the container div instead of the actual image.

This would work:

.image-cropper {
  width: 100px;
  height: 100px;
  position: relative;
  overflow: hidden;
  border-radius: 50%;
}

img {
  display: inline;
  margin: 0 auto;
  height: 100%;
  width: auto;
}

<div class="image-cropper">
  <img src="https://via.placeholder.com/150" class="rounded" />
</div>
