Transform your 2D image into a 3D one using a few lines of code

3D images using CSS

img {
  --d: 18px;  /* the depth */
  --a: 20deg; /* the angle */
  
  /* the below value is based on the depth and the angle.
     the formula is a bit difficult to express so we update it manually
  */
  --x: 10px;
  
  width: 250px; /* control the size */
  aspect-ratio: 1.1; /* you can use 1 as ratio but I found 1.1 a little better */
  padding-block: var(--d);
  transform: perspective(400px) rotateY(calc(var(--_i,1)*var(--a)));
  outline: var(--d) solid #0008;
  outline-offset: calc(-1*var(--d));
  --_d: calc(100% - var(--d));
  --_l: 0px;
  --_r: 0px;
  clip-path: polygon(
    var(--_l) calc(var(--_d) - var(--x)),
    var(--_l) calc(var(--d)  + var(--x)), 
    var(--d) var(--d),var(--_d) var(--d),
    calc(var(--_d) + var(--_r)) calc(var(--d)  + var(--x)),
    calc(var(--_d) + var(--_r)) calc(var(--_d) - var(--x)),  
    var(--_d) var(--_d),var(--d) var(--_d)
   );
  transition: transform .3s,--_r .15s,--_l .15s .15s;
  transition-timing-function: linear;
}
img:hover {
  --_l: var(--d);
  --_r: var(--d);
