Simple Success Loader Animation

Code Feedback
1

Hey all,

I made a simple (S)CSS based loader animation with a success end point. Thought I would share here in case anyone wishes to use it and to ask for some feedback/ways to improve it.

I know there are multiple libraries which do this sort of thing, just wanted to make one myself to learn and then get feedback on.

Some code:

SCSS

.loader {
    position: absolute;
    content: '';
    top: calc(50% - 2.5rem);
    left: calc(50% - 2.5rem);
    width: 5rem;
    height: 5rem;
    border: 5px solid lightGreen;
    border-radius: 50%;
    animation: spin 1s linear infinite;
    overflow: hidden;
    transition: 0.3s;
    background: lightGreen;
    box-shadow: 0rem 0rem 0.6rem rgba(0,0,0,0.3);
    
    .line-long {
      height: 7px;
      width: 2.5rem;
      position: absolute;
      top: 65%;
      left: 44%;
      background-color: green;
      transform: rotate(-45deg);
      transform-origin: 0% 50%;
      border-radius: 5px;
      animation: baseGrow 1s;
    }
    
    .line-short {
      height: 7px;
      width: 1.5rem;
      position: absolute;
      top: 65%;
      left: 50%;
      background-color: green;
      transform: rotate(-135deg);
      transform-origin: 0% 50%;
      border-radius: 5px;
      animation: tipGrow 1s;
    }
    
}

@keyframes spin {
  0% {
    transform: rotate(0deg);
        border-top: 5px solid darkGreen;
  }
  100% {
    transform: rotate(360deg);
        border-top: 5px solid darkGreen;

  }
}

@keyframes tipGrow {
  0% {
    width: 0px;
    left: 0;
    top: 0;
  }
  25% {
    width: 0px;
    left: 0;
    top: 0; 
  }
  50% {
    top: 0%;
    left: 0%;
    width: 0;
  }
  75% {
    top: 0%;
    left: 0%;
    width: 0rem;
  }
  100% {
    top: 65%;
    left: 50%;
    width: 1.5rem;
  }
}

@keyframes baseGrow {
  0% {

    width: 0;
  }
  90% {
    width: 0;
  }
  100% {

    width: 2.5rem;
  }
}

@keyframes pop {
  0% {
    transform: scale(1);
  }
  80% {
    transform: scale(1);    
  }
  100% {
    transform: scale(1.1);
  }
}

Javascript

const tickBase = document.createElement('span');
const tickFoot = document.createElement('span');
const loader = document.querySelector('.loader');
tickBase.classList.add('line-long');
tickFoot.classList.add('line-short');

function finish () {
  loader.appendChild(tickBase);
  loader.appendChild(tickFoot);
  loader.style.animation = 'none';
  loader.style.animation = 'pop 1.2s ease-in-out';
}

setTimeout(() => finish(), 2000);

HTML

<span class="loader">
</span>

Nice! I think that you should add it to a sample login page then post your project here.
