Acrobatic Preloader using CSS is a cool project. We can use this kind of preloader to entertain users while we load the webpage. Sometimes webpages take a long time to load, While the page is loading users see a blank white screen. Instead, we can show them a preloader to indicate the page is loading.

How to create an Acrobatic Preloader using CSS?
To create this kind of preloader we can use SVG and CSS.
Step 1: HTML
First, We will create an HTML file with the below code.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<link rel="stylesheet" href="style.css" />
<title>Acrobatic Preloader using CSS</title>
</head>
<body>
<main>
<svg
class="ap"
viewBox="0 0 128 256"
width="128px"
height="256px"
xmlns="http://www.w3.org/2000/svg"
>
<defs>
<linearGradient id="ap-grad1" x1="0" y1="0" x2="0" y2="1">
<stop offset="0%" stop-color="hsl(223,90%,55%)" />
<stop offset="100%" stop-color="hsl(253,90%,55%)" />
</linearGradient>
<linearGradient id="ap-grad2" x1="0" y1="0" x2="0" y2="1">
<stop offset="0%" stop-color="hsl(193,90%,55%)" />
<stop offset="50%" stop-color="hsl(223,90%,55%)" />
<stop offset="100%" stop-color="hsl(253,90%,55%)" />
</linearGradient>
</defs>
<circle
class="ap__ring"
r="56"
cx="64"
cy="192"
fill="none"
stroke="#ddd"
stroke-width="16"
stroke-linecap="round"
/>
<circle
class="ap__worm1"
r="56"
cx="64"
cy="192"
fill="none"
stroke="url(#ap-grad1)"
stroke-width="16"
stroke-linecap="round"
stroke-dasharray="87.96 263.89"
/>
<path
class="ap__worm2"
d="M120,192A56,56,0,0,1,8,192C8,161.07,16,8,64,8S120,161.07,120,192Z"
fill="none"
stroke="url(#ap-grad2)"
stroke-width="16"
stroke-linecap="round"
stroke-dasharray="87.96 494"
/>
</svg>
</main>
</body>
</html>
Step 2: CSS
Last, We will create a style.css and add the below code to it.
* {
border: 0;
box-sizing: border-box;
margin: 0;
padding: 0;
}
:root {
--hue: 223;
--bg: hsl(var(--hue), 10%, 90%);
--fg: hsl(var(--hue), 10%, 10%);
font-size: calc(16px + (24 - 16) * (100vw - 320px) / (1280 - 320));
}
body {
background-color: var(--bg);
color: var(--fg);
font: 1em/1.5 sans-serif;
height: 100vh;
display: grid;
place-items: center;
transition: background-color 0.3s;
}
main {
padding: 1.5em 0;
}
.ap {
width: 8em;
height: 16em;
}
.ap__ring {
stroke: hsla(var(--hue), 10%, 10%, 0.15);
transition: stroke 0.3s;
}
.ap__worm1,
.ap__worm2 {
animation-duration: 3s;
animation-iteration-count: infinite;
}
.ap__worm1 {
animation-name: worm1;
}
.ap__worm2 {
animation-name: worm2;
visibility: hidden;
}
/* Dark theme */
@media (prefers-color-scheme: dark) {
:root {
--bg: hsl(var(--hue), 10%, 10%);
--fg: hsl(var(--hue), 10%, 90%);
}
.ap__ring {
stroke: hsla(var(--hue), 10%, 90%, 0.1);
}
}
/* Animtions */
@keyframes worm1 {
from {
animation-timing-function: ease-in-out;
stroke-dashoffset: -87.96;
}
20% {
animation-timing-function: ease-in;
stroke-dashoffset: 0;
}
60% {
stroke-dashoffset: -791.68;
visibility: visible;
}
60.1%,
to {
stroke-dashoffset: -791.68;
visibility: hidden;
}
}
@keyframes worm2 {
from,
60% {
stroke-dashoffset: -87.96;
visibility: hidden;
}
60.1% {
animation-timing-function: cubic-bezier(0, 0, 0.5, 0.75);
stroke-dashoffset: -87.96;
visibility: visible;
}
77% {
animation-timing-function: cubic-bezier(0.5, 0.25, 0.5, 0.88);
stroke-dashoffset: -340;
visibility: visible;
}
to {
stroke-dashoffset: -669.92;
visibility: visible;
}
}
Boom! You have created a preloader.
