You need to divide by 2 every values involved, even the clip(); ones (fiddle updated)

edit: in respond to comment @Filipe

How would the change from clip to clip-path be? I tried (also changing rect to inset), but the animation stops working.

Possible example with clip-path instead clip .

Animating circular image border - HTML & CSS - SitePoint Forums | Web Development & Design Community

June 21, 2021 - One half circle hides the other one until a half animation is complete and then the other half is animated to complete the circle. There is no border as such but a solid background which is hidden by the inner elements to just allow the edge of the circles to be seen.

There is a very easy to follow, informative and detailed tutorial on exactly how to achieve this (and more) by Anders Ingemann, which can be found here.

Its a fairly complex operation- so I'll simply distil the final stage from the tutorial here

Demo Fiddle

HTML

<div class="radial-progress">
    <div class="circle">
        <div class="mask full">
            <div class="fill"></div>

        </div>
        <div class="shadow"></div>
    </div>
    <div class="inset"></div>

CSS/LESS

.radial-progress {
    @circle-size: 120px;
    @circle-background: #d6dadc;
    @circle-color: #97a71d;

Example jQuery (could be substituted with CSS)

$('head style[type="text/css"]').attr('type', 'text/less');
less.refreshStyles();

window.randomize = function () {
    var rotation = Math.floor(Math.random() * 180);
    var fill_rotation = rotation;
    var fix_rotation = rotation * 2;
    for (i in transform_styles) {
        $('.circle .fill, .circle .mask.full').css(transform_styles[i], 'rotate(' + fill_rotation + 'deg)');
        $('.circle .fill.fix').css(transform_styles[i], 'rotate(' + fix_rotation + 'deg)');
    }

If you want the inner circle to be a cutout and see the content behind u can achieve the same effect using box-shadow This is the update

.circle2 {
 --circle-size: 200px;
 --fill-circle: calc(circle-size / 2);
 --stroke-size: 10px;
 width: var(--circle-size);
 height: var(--circle-size);
 background-color: pink;
 border-radius: 100vh;
 background: transparent;
 box-shadow: inset 0 0 0 var(--circle-size) lightblue;
 animation: parentFromCenter 1s ease-in forwards, shadow 1s 1s ease-in forwards;

Awesome CSS Border Animation Examples to Use in Your Websites

January 27, 2026 - Jessica Aiskel’s fancy border animation demonstrates how creative use of the border-radius property can create unique container shapes that stand out from conventional rectangles and circles. This technique uses multiple radius values to create complex curves that add visual interest to containers and buttons. The resulting shapes create distinctive visual elements that reinforce brand identity and improve recognition. ... Michelle Barker’s Chrome-specific animation leverages the CSS Houdini API to create advanced gradient effects beyond standard CSS capabilities.

December 15, 2016 - CSS code: .circle__spin circle { stroke-width: 5; /* control the dashes width */ stroke-dasharray: 120, 20; /* control the dashes spacing */ fill: none; stroke: orange; } Note that the circle radius is calculated this way: circle radius= ((circle height) +(2*stroke-width ) +(desired border to circle spacing)) / 2 67px = ((120px) + (2*5px)+ (4px)) / 2 · And finally you can add the animation.

html - CSS ONLY Animate Draw Circle with border-radius and transparent background - Stack Overflow

codepen.io › OlegJR › pen › bGpxMvr

This is my solution.

I set a background on body to show it is transparent

body {
  background: repeating-linear-gradient(45deg, white 0px, lightblue 100px);
  height: 500px;
  background-size: 500px 500px;
  background-repeat: no-repeat;
}

html {
  height: 100%;
}

#container {
  position: absolute;
  width: 400px;
  height: 400px;
   border: solid red 1px;
   animation: colors 4s infinite;
}

#halfclip {
  width: 50%;
  height: 100%;
  right: 0px;
  position: absolute;
   overflow: hidden;
   transform-origin: left center;
   animation: cliprotate 16s steps(2) infinite;
   -webkit-animation: cliprotate 16s steps(2) infinite;
}

.halfcircle {
  box-sizing: border-box;
  height: 100%;
  right: 0px;
  position: absolute;
  border: solid 25px transparent;
   border-top-color: blue;
   border-left-color: blue;
   border-radius: 50%;
}
#clipped {
  width: 200%;
   animation: rotate 8s linear infinite;
   -webkit-animation: rotate 8s linear infinite;
}
#fixed {
  width: 100%;
    transform: rotate(135deg);  
   animation: showfixed 16s steps(2) infinite;
   -webkit-animation: showfixed 16s linear infinite;
}

@-webkit-keyframes cliprotate {
  0% {transform: rotate(0deg);}
  100% {transform: rotate(360deg);}
}

@keyframes cliprotate {
  0% {transform: rotate(0deg);}
  100% {transform: rotate(360deg);}
}


@-webkit-keyframes rotate {
  0% {transform: rotate(-45deg);}
  100% {transform: rotate(135deg);}
}

@keyframes rotate {
  0% {transform: rotate(-45deg);}
  100% {transform: rotate(135deg);}
}

@-webkit-keyframes showfixed {
  0% {opacity: 0;}
  49.9% {opacity: 0;}
  50% {opacity: 1;}
 100% {opacity: 1;}
}

<div id="container">

        </div>
    </div>
    <div class="halfcircle" id="fixed">
    </div>
</div>

And this is a variation on the solution, to make it run only once on hover

body {
  background: repeating-linear-gradient(45deg, white 0px, lightblue 100px);
  height: 500px;
  background-size: 500px 500px;

  width: 300px;
  height: 300px;
   border: solid red 1px;
}

#halfclip {
    width: 50%;
    height: 100%;
    right: 0px;
    position: absolute;
    overflow: hidden;
    transform-origin: left center;
}

#container:hover #halfclip {
    animation: cliprotate 6s 1;
    transform: rotate(180deg);
} 

@keyframes cliprotate {
  0% {transform: rotate(0deg);}
  50% {transform: rotate(0deg);}
  50.01% {transform: rotate(180deg);}
  100% {transform: rotate(180deg);}
}

.halfcircle {
  box-sizing: border-box;
  height: 100%;
  right: 0px;
  position: absolute;
  border: solid 25px transparent;
   border-top-color: blue;
   border-left-color: blue;
   border-radius: 50%;
}

#clipped {
    width: 200%;
    transform: rotate(-45deg);
}
#container:hover #clipped {
    transform: rotate(135deg);
    animation: rotate 3s linear 2;
}


@keyframes rotate {
  0% {transform: rotate(-45deg);}
  100% {transform: rotate(135deg);}
}


#fixed {
