Hi Folks,
Loading component is a very common requirement in react to represent the loading state. In this tutorial, I will explain how you can create bouncing dots loader using CSS.
We will be creating a loader as shown below -
Let's get started -
For this tutorial, I'm assuming you already have a React project setup ready with you.
Now, let's create a BouncingDotsLoader component in React and add JSX to create those three dots.
BouncingDotsLoader.js
import React from "react";
const BouncingDotsLoader = (props) => {
return (
<div className="bouncing-loader">
<div></div>
<div></div>
<div></div>
</div>
);
};
export default BouncingDotsLoader;
Let's understand the above code-
Here, I have created an outer div container to wrap all the
three identical dots with class bouncing-loader
. To create these three dots, I've added three div element inside this container.
Now, Let's add CSS to style the dots-
.bouncing-loader {
display: flex;
justify-content: center;
}
.bouncing-loader > div {
width: 16px;
height: 16px;
margin: 3px 6px;
border-radius: 50%;
background-color: #a3a1a1;
opacity: 1;
animation: bouncing-loader 0.6s infinite alternate;
}
Let's understand the above CSS -
I've added display: flex
and justify-content: center
to bouncing-loader
class to make those dots inline & center. Also, added CSS to bouncing-loader > div
to style each dot with an animation
shortand property with value bouncing-loader 0.6s infinite alternate
representing CSS properties animation-name animation-duration iteration-count animation-direction
.
It will look like this -
Let's add the final CSS to create the bouncing effect-
@keyframes bouncing-loader {
to {
opacity: 0.1;
transform: translateY(-16px);
}
}
.bouncing-loader > div:nth-child(2) {
animation-delay: 0.2s;
}
.bouncing-loader > div:nth-child(3) {
animation-delay: 0.4s;
}
Let's understand the final CSS -
I've added keyframes to the bouncing-loader animation at start point with opacity: 0.1
& transform: translateY(-16px)
& delayed the animation for second and third dot with 0.2 & 0.4 seconds respectively.
This way, Our very simple bouncing dots loader is ready.
