Rating component with simple animations

My second challenge. First time dealing with css animations and I have a question:

• what's the best way to retrigger css animation from vanilla JS? I used this rather hacky looking way of re-adding a class:

  radios.classList.remove('card__radios--alert')
  radios.offsetWidth //wtf
  radios.classList.add('card__radios--alert')
  

  but I think in modern css/js there should be a better way
