Create a Spinner Loader in React using CSS

Hi Folks,

In this article, we'll talk about how to create a spinner loader in React using pure CSS.

We will be creating a loader as shown below -

Let's start creating a file called spinner.js in the react project and add some JSX to it for the loader.

File: Spinner.js

const Spinner = () => <div className="loader"></div>;

export default Spinner;

Let's understand the above code -

Here, we have created a functional component called Spinner. Which is returning a div element with a class loader. That's all the JSX required for it.

Now, Let's add css for it.

.loader {
  border: 10px solid #f3f3f3;
  border-top: 10px solid #3498db;
  border-radius: 50%;
  width: 80px;
  height: 80px;
  animation: spin 1s linear infinite;
}

Let's understand the above CSS -

We've added border:10px solid #f3f3f3 property to create the gray circle and border-top: 10px solid #3498db to create the blue colored arc on top of the gray colored circle. After that border-radius: 50% property to make it circular and have given same amount of height & width.

Now, to add the spinning effect we've added animation: spin 1s linear infinite.

It will look like this -

Let's add the final CSS to create the spinning effect-

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

Let's understand the final CSS -

Here, we have added keyframes for the spin animation. Where we are rotating the element using transform: rotate() property from 0 degree to 360 degree.

Finally, Our Sinnner loader is ready.
