One of the fundamental principles of User Experience (UX) is that a visitor expects to see some feedback when they do actionable work on a website or an app. For example, when you click on a download button to download a file to your machine, the file processes in the background. On the front, till the file is ready, we want to let the user know that some process is running in the background, and they have to wait for a few seconds till the download begins. Here the CSS loader can be helpful. Let’s see the best and unique CSS loaders.
If the website shows nothing, most users will conclude that something is wrong with your site. By doing this, they will be able to navigate away before they realize your site has been processing their request!
You don’t want that to happen, so to solve this issue in CSS, we have the concept of adding a ‘loading’ state. This animation lets the user know that their request has been received and that the site is loading some relevant information.
Now, how to make one? If you have never coded a CSS loader, or just want to get some inspiration for some of the best ones, we have curated it all for you in this article.

CSS Loaders (CodePen)
The following CSS loaders are available as CodePen demos:
1. Neumorphism Gradient Loader
This loader is a mixed breed of both neumorphism and gradient design – the two highly trending things in the frontend world as of now.
What’s unique?
It heavily relies on box-shadows , pseudo-classes and the filter property to achieve this effect.
// Box shadow
box-shadow: -5px -5px 5px rgba(255, 255, 255, 0.1),
10px 10px 10px rgba(0, 0, 0, 0.4),
inset -5px -5px 5px rgba(255, 255, 255, 0.2),
inset 10px 10px 10px rgba(0, 0, 0, 0.4);
// Pseudo class
.loader:before {
content: "";
.
.
.
}
// Filter property
filter: blur(20px);
2. Loading Animation w/ Translate and Z-index
These blue-shaped circles showcase the best depth effect between themselves thanks to the different z-index values they have. They also animate on top of each other for a more natural transition.
What’s unique?
Not only z-index, but also it has some cool blue linear-gradient and transform properties on the x-axis.
// Linear gradient
background: linear-gradient(45deg,
rgba(2,0,36,1) 0%,
rgba(9,9,121,1) 35%,
rgba(0,212,255,1) 100%);
// Z-index and transforms
@keyframes move-1 {
0% {z-index: 3; transform: translateX(0);}
.
.
.
100% {z-index: 1; transform: translateX(0);}
}
3. Pure CSS loader #30: 1 element metaballs animation
Well, here is a meatball sticking to various other balls (circles) in a smooth animation.
Take a look at how it attaches to two and one of the balls on different axes. This is something appreciable!
What’s unique?
First of all, the code is in SASS (.scss) and therefore you can expect some cool use cases of the same with custom variables, @for flow control, and CSS blend mode.
// Custom variables
$n: 10;
$r: 1.5em;
$oa: -90deg;
$ba: 360deg/$n;
$hl: 2*$r;
.
.
.
// Flow control
@for $i from 0 to $n {
$ca: $oa + $i*$ba;
$sh: $sh,
$rc*cos($ca) $rc*sin($ca) currentcolor
}
// Blend mode
.loader {
.
.
.
mix-blend-mode: multiply;
.
.
.
}
4. Pure CSS loader #31 – 1 element swappy
Here’s a cool swappy animation where you have a box container inside which we have a circle that morphs or ‘swaps’ away from its shape after a set interval of time. It goes from a circle to a square to again a circle.
What’s unique?
- The animation values can be changed dynamically as per your liking as it uses SASS variables.
- The use of @for inside the animation @keyframes code.
- Use of clip-path to morph the shape.
// Dynamic animation
body { .
.
.
animation: fsx 4*$t steps(1) infinite
}
// Use of @for inside @keyframes
@keyframes fbg {
@for $i from 0 to $n {
#{$i/$n*100%} { background: nth($c, $i + 1) }
}
}
// Use of clip-path
@keyframes exp {
0%, #{$q} { clip-path: inset(0 .5*$d $d round 50%) }
100% { clip-path: inset(0 round 50%/ 0) }
}5. Spiral Loading
Need something infinite? This loading animation goes on and on with a soothing spiral shape. The good part is that towards the end it fades away and towards its origin, it stays solid white. It gives an immersive and soothing loading experience.
What’s unique?
You can change the number of circles you want to have in the spiral, the diameter, radius, and duration. It makes a ring of circles by using the transform: rotate() function.
// Control the amount of circles, diameter, radius and duration
.circle {
$circle-count: 60;
$circle-diameter: 0.5em;
$ring-radius: 4em;
$duration: 3s;
.
.
.
}
// Using rotate() to make a ring of circles
transform: rotate($ratio * 720deg) translateX($ring-radius);
6. Liquid Loader
Imagine a loader that is like a two-way open pipe. On one end, it takes in some liquid, and on the other one, it spits out the same liquid. Sound weird?
Then add an ultra-cool gradient to it and make it realistic with amazing shadow play. This is the liquid loader you don’t want to miss to take a look!
What’s unique?
It uses CSS filter property and many of the CSS-SVG values like stop-color, stroke-dasharray and more!
// CSS filter
.skugga {
filter: blur(5px);
.
.
.
}
// CSS-SVG values
.strecken {
stroke-dasharray: 26 54;
fill: none;
stroke: url(#gradient);
stroke-width: 23;
stroke-linecap: round;
}
7. Gradient Spinner
This looks like the perfect match for your upcoming meditation or breathing app. Or maybe it can also be used on a smart home appliance website where you want to mimic the dial functionality via a loading animation.
What makes it great is the choice of animation speed and the gradient color. It’s not too much and it fits so well!
What’s unique?
- Use of
linear-gradientvalues. - It uses the
blurfilter. - Pseudo-classes like
:nth-child()and:afterare used..loader {
.
.
.
background: linear-gradient(#f07e6e, #84cdfa, #5ad1cd);
animation: animate 1.2s linear infinite;}
8. Hexagon Loading With CSS (2)
It’s nothing but one of the simplest animations you can offer on your website. A thin-line hexagon forms itself and completes its shape in a loop.
What’s unique?
It achieves this effect by using the transform: rotate() function and with extra cautious values of @keyframes.
// Use of rotate
div:nth-of-type(2){transform:rotate(60deg)}
div:nth-of-type(3){transform:rotate(-60deg)}
// Use of precise values in @keyframes
@keyframes load1 {
0%{bottom:0;height:0}
6.944444444%{bottom:0;height:100%}
50%{top:0;height:100%}
59.944444433%{top:0;height:0}
/* 91.6666667%{top:0;height:0%;} */
}
9. Terminal Spinner
In love with your terminal where you run various commands? Well, then why not make a CSS loader out of it?
This one is monochrome (just as all terminal things should be), it flashes and blinks in a conform cycle and it does it all well!
What’s unique?
The clever use of pseudo-classes combined with an animation block, which in itself uses the content property.
// Pseudo class
.spinner:after {
animation: changeContent .8s linear infinite;
display: block;
content: "⠋";
font-size: 80px;
}
// The animation block
@keyframes changeContent {
10% { content: "⠙"; }
20% { content: "⠹"; }
30% { content: "⠸"; }
40% { content: "⠼"; }
50% { content: "⠴"; }
60% { content: "⠦"; }
70% { content: "⠧"; }
80% { content: "⠇"; }
90% { content: "⠏"; }
}
10. Weird Loader
Talk about loaders being drunk! This is a set of two circles that feel like they are competing with each other in the Weirdest of All Competition!
If your website is funky and quite animated, then this one will suit you the best.
What’s unique?
It has some of the best animation stops used which gives it a weird animation feel
// Use of animation stops
@keyframes circle--1 {
0% {
top: 50%;
}
50% {
top: 120%;
}
100% {
top: 50%;
}
}
@keyframes circle--2 {
0% {
top: 50%;
}
50% {
