Animacion de control input text

Publicado por Maria Elena (3 intervenciones) el 16/09/2021 13:57:39
Hola a todos! Espero puedan ayudarme. Soy nueva en JS.
He personalizado un control input (he conseguido en la web como hacer esto) y funciona muy bien pero solo para el primer control. No se como hacerlo funcionar para el resto de input's del formulario.

<div class='ctrl__button ctrl__button--decrement'>&ndash;</div>
                          <div class='ctrl__counter'>
                              <input class='ctrl__counter-input'   maxlength='3' type='text' value='0'>
                            <div class='ctrl__counter-num'>0</div>
                          </div>
                          <div class='ctrl__button ctrl__button--increment'>+</div>
