Skeleton Loading: Enhancing the User Experience during Content Loading

When building web applications, one of the primary challenges is ensuring a smooth and seamless user experience. Slow loading times and content «jumps» can lead to frustrated users and potential abandonment of your website. One popular solution to this problem is using skeleton loading, a technique that creates a placeholder for content while it's loading to improve perceived performance and maintain a consistent layout.

In this article, we will discuss what skeleton loading is, why it's essential, and how to implement it in your web applications.

What is Skeleton Loading?

Skeleton loading, also known as content placeholders or skeleton screens, is a technique where a simple wireframe or shape of the content is displayed before the actual content loads. These placeholders create an illusion of faster loading times by giving users an immediate visual feedback and maintaining the layout's consistency.

Skeleton loading can be applied to various types of content, including text, images, and even complex components like cards or lists. The main goal is to provide users with a smooth and uninterrupted experience while they wait for the actual content to load.

Why is Skeleton Loading Important?

There are several benefits to implementing skeleton loading in your web applications:

  1. Perceived Performance: Skeleton loading creates a perception of faster loading times by providing immediate visual feedback. Users are less likely to notice delays, and it helps reduce the chances of users abandoning your site due to slow load times.
  2. Consistent Layout: By displaying placeholders for content, skeleton loading maintains the layout's consistency, preventing sudden layout shifts or content «jumps» when the actual content loads.
  3. Improved User Experience: A smooth and seamless user experience is crucial for retaining users and ensuring their satisfaction with your website. Skeleton loading contributes to this by providing a more polished and professional feel during content loading.

Implementing Skeleton Loading

There are various ways to implement skeleton loading, depending on the technology stack and tools you use. Below, we will discuss two popular approaches: CSS and React.

CSS-based Skeleton Loading

One of the simplest ways to implement skeleton loading is using pure CSS. This method involves creating a CSS class for the skeleton loader and applying it to the content elements while they are loading.

First, create a CSS class for the skeleton loader:

  1. .skeleton-loader {
  2. background: linear-gradient(90deg, #f0f0f0 25%, #e0e0e0 50%, #f0f0f0 75%);
  3. background-size: 200% 100%;
  4. animation: loading 1.5s infinite;
  5. }
  6.  
  7. @keyframes loading {
  8. 0% {
  9. background-position: 200% 0;
  10. }
  11. 100% {
  12. background-position: -200% 0;
  13. }
  14. }

This CSS class defines a simple animation for the skeleton loader, creating a shimmering effect as the gradient background moves.

Next, apply the `.skeleton-loader` class to the content elements you want to show the skeleton loader for:

  1. <div class="skeleton-loader" style="width: 100%; height: 20px;"></div>

Adjust the `width` and `height` styles to match the dimensions of your content elements. Once your content is loaded, remove the .skeleton-loader class to reveal the actual content.

React-based Skeleton Loading

If you are using React, you can create a reusable skeleton loading component to make implementing skeleton loaders across your application even more straightforward.

First, create a new `SkeletonLoader.js` file:

  1. import React from 'react';
  2. import './SkeletonLoader.css';
  3.  
  4. const SkeletonLoader = ({ width, height }) => (
  5. <div
  6. className="skeleton-loader"
  7. style={{ width: `${width}px`, height: `${height}px` }}
  8. />
  9. );
  10.  
  11. export default SkeletonLoader;

Next, create a `SkeletonLoader.css` file with the same CSS code for the skeleton loader as mentioned in the CSS-based approach:

  1. .skeleton-loader {
  2. background: linear-gradient(90deg, #f0f0f0 25%, #e0e0e0 50%, #f0f0f0 75%);
  3. background-size: 200% 100%;
  4. animation: loading 1.5s infinite;
  5. }
  6.  
  7. @keyframes loading {
  8. 0% {
  9. background-position: 200% 0;
  10. }
  11. 100% {
  12. background-position: -200% 0;
  13. }
  14. }

Now, you can use the `SkeletonLoader` component in any part of your application where you want to display a skeleton loader:

  1. import React, { useState, useEffect } from 'react';
  2. import SkeletonLoader from './SkeletonLoader';
  3.  
  4. const MyComponent = () => {
  5. const [data, setData] = useState(null);
  6.  
  7. useEffect(() => {
  8. // Fetch your data here and set it to `setData`
  9. }, []);
  10.  
  11. return (
  12. <div>
  13. {data ? (
  14. <div>{data.text}</div>
  15. ) : (
  16. <SkeletonLoader width={100} height={20} />
  17. )}
  18. </div>
  19. );
  20. };
  21.  
  22. export default MyComponent;

In this example, we use the `SkeletonLoader` component while the `data` is being fetched. Once the data is available, the actual content will replace the skeleton loader.

Conclusion

Skeleton loading is an effective technique for improving the perceived performance and user experience of your web applications. By using simple CSS or React components, you can easily implement skeleton loading and create a smooth, consistent experience for users while they wait for content to load. Give it a try and see how it can enhance your web projects!
