I’m working on a toggle, this is my code:

import style from "./Toggle.module.scss";

export default function Toggle() {
    return (
        <>
            <input type="checkbox" id="toggle" className={style.toggle} />
            <label htmlFor="toggle" className={style.label} />
        </>
    );
}


.toggle {
    height: 0;
    width: 0;
    opacity: 0;
}

.label {
    width:60px;
    height: 30px;
    border-radius:30px;
    display: block;
    background-color: #ebebeb;
    box-shadow: 1px 2px 5px 1px rgba(0,0,0,0.2) inset;
    left:10px;
    padding-left: 5px;
    position: relative;
    
    &::after {
        content: '';
        position: absolute;
        width: 23px;
        height: 23px;
        border-radius: 50px;
        background-color: green;
        top: 50%;
        transform: translateY(-50%);
        transition: 0.3s;
        
    }
}

.toggle:checked ~ .label::after{
    
    transform: translateX(32px);
    


}

initially the knob is perfectly centered inside the switch, but when i click it, it makes a diagonal movement instead of moving in a straight line to the right. See codesandbox for details.

  1. You need to add the translateY: -50% to the toggled transformation as well if you don’t that value will not be added to the transformation:

    .toggle {
      height: 0;
      width: 0;
      opacity: 0;
    }
    
    .label {
      width: 60px;
      height: 30px;
      border-radius: 30px;
      display: block;
      background-color: #ebebeb;
      box-shadow: 1px 2px 5px 1px rgba(0, 0, 0, 0.2) inset;
      left: 10px;
      padding-left: 5px;
      position: relative;
    
      &::after {
        content: "";
        position: absolute;
        width: 23px;
        height: 23px;
        border-radius: 50px;
        background-color: green;
        top: 50%;
        transform: translateY(-50%);
        transition: 0.3s;
      }
    }
    
    .toggle:checked ~ .label::after {
      transform: translateX(32px) translateY(-50%);
    }

  2. One solution is:

    &::after {
      ...
      top: 4px
      transform: translateX(0);
      ...
    }
    
    .toggle:checked ~ .label::after {
      transform: translateX(28px);
    }
    

    notice the translateX from translateY, since you’re moving horizontally you don’t need to set the Y axis at all.
