CSSBattle | #27 Lock Up

Welcome to CSSBattle Challenges!

In this short article, I go through my solution for CSSBattle - #27 Lock Up challenge. Please refer to the code snippet below to get a better insight into my thought processes and the implementation detail.


Lock Up Challenge


<div class="container">
  <div class="red-circle"></div>
  <div class="yellow-circle-borders"></div>

  * {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
  .container {
    background: #E38F66;
    width: 100vw;
    height: 100vh;
    position: relative;
  .red-circle {
    position: absolute;
    width: 200px;
    height: 200px;
    border-radius: 50%;
    background: #AA445F;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
  .yellow-circle-borders {
    border: 30px solid #F7EC7D;
    width: 140px;
    height: 140px;
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%) rotate(45deg);
    border-radius: 50%;
    border-left-color: transparent;
    border-right-color: transparent;
Enter fullscreen mode Exit fullscreen mode

Key Takeaway(s):

  • using transparent border colors to hide the entirety of an element's shape

As always, I welcome any feedback or questions regarding the implementation detail of the challenge. Otherwise, I hope this was useful!
