  transform: rotate(calc(30deg * var(--i)));
  inset: 12px;
  text-align: center;

.clock span b{
  transform: rotate(calc(-30deg * var(--i)));
  display: inline-block;

   let hRotation = 30*hh + mm/2;
   let mRotation = 6*mm;
   let sRotation = 6*ss; = `rotate(${hRotation}deg)`; = `rotate(${mRotation}deg)`; = `rotate(${sRotation}deg)`;

setInterval(displayClock, 1000);
