hight is equal to image css code example

Example: equal height and width image css

.container {
  position: relative;
  width: 37%; /* The size you want */
}
.container:after {
  content: "";
  display: block;
  padding-bottom: 100%; /* The padding depends on the width, not on the height, so with a padding-bottom of 100% you will get a square */
}

.container img {
  position: absolute; /* Take your picture out of the flow */
  top: 0;
  bottom: 0;
  left: 0;
  right: 0; /* Make the picture taking the size of it's parent */
  width: 100%; /* This if for the object-fit */
  height: 100%; /* This if for the object-fit */
  object-fit: cover; /* Equivalent of the background-size: cover; of a background-image */
  object-position: center;
}
