What is a React loading spinner?

Can you explain what a React loading spinner is?

A React loading spinner is a visual indicator that shows users that content is being loaded in a React application.

How do I implement a loading spinner in my React app?

You can use libraries like 'react-spinners' or create a custom spinner using CSS and conditional rendering.

Can you show me a simple code example?

Sure! Here's a basic example using CSS:

function LoadingSpinner() {
  return <div className='spinner'></div>;
}

And in your CSS:

.spinner {
  border: 8px solid #f3f3f3;
  border-top: 8px solid #3498db;
  border-radius: 50%;
  width: 50px;
  height: 50px;
  animation: spin 2s linear infinite;
}
@keyframes spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(360deg); }
}

What if I want to customize the spinner's color?

You can change the border-top color in the CSS to any color you like to customize the spinner.
