How to Create a CSS Progress Circle that Stops at Specific Percentages?

CSS Progress Circle with Partial Completion Indication

Introduction:

Circular progress bars are a common UI element used to indicate progress or completion status. However, many CSS progress bars display full animations that reach 100%. This article demonstrates how to create a CSS progress circle that can stop at specific percentages, as seen in the screenshot below:

Solution:

To achieve this, we utilize CSS clipping and animations. The clip property is used to hide a portion of the progress circle, while the animation property defines the rotation of the circle.

CSS Code:

.wrapper {
  width: 100px;
  height: 100px;
  position: absolute;
  clip: rect(0px, 100px, 100px, 50px);
}

.circle {
  width: 80px;
  height: 80px;
  border: 10px solid green;
  border-radius: 50px;
  position: absolute;
  clip: rect(0px, 50px, 100px, 0px);
}

div[data-anim~=base] {
  -webkit-animation-iteration-count: 1; 
  -webkit-animation-fill-mode: forwards; 
  -webkit-animation-timing-function:linear; 
}

.wrapper[data-anim~=wrapper] {
  -webkit-animation-duration: 0.01s; 
  -webkit-animation-delay: 3s; 
  -webkit-animation-name: close-wrapper; 
}

.circle[data-anim~=left] {
  -webkit-animation-duration: 6s; 
  -webkit-animation-name: left-spin;
}

.circle[data-anim~=right] {
  -webkit-animation-duration: 3s; 
  -webkit-animation-name: right-spin;
}

@-webkit-keyframes right-spin {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(180deg);
  }
}

@-webkit-keyframes left-spin {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(360deg);
  }
}

@-webkit-keyframes close-wrapper {
  to {
    clip: rect(auto, auto, auto, auto);
  }
}

HTML Code:

<div class="wrapper" data-anim="base wrapper">
  <div class="circle" data-anim="base left"></div>
  <div class="circle" data-anim="base right"></div>
</div>

This solution ensures that the progress circle animates smoothly, with the ability to pause at specific percentages, as desired.
