Tips and methods of CSS loading animation effects

With the development of the Internet, loading speed has become one of the important indicators of user experience. In order to improve the user experience when the page is loading, we usually use loading animation effects to increase the interactivity and attractiveness of the page. As one of the important technologies in front-end development, CSS provides many techniques and methods to achieve loading animation effects.

This article will introduce several common CSS loading animation effects implementation techniques and methods, and provide corresponding code examples.

1. Rotating loading animation

Rotating loading animation is a common loading animation effect that gives users a sense of loading progress by rotating an element along the center point. Feel. The following is a code example to implement a rotating loading animation:

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

.loader {
  width: 50px;
  height: 50px;
  border: 5px solid #f3f3f3;
  border-top: 5px solid #3498db;
  border-radius: 50%;
  animation: spin 2s linear infinite;
}

2. Jump loading animation

Jump loading animation is a lively loading animation effect, by making the element Jump on the page to show the loading process. The following is a code example to implement jump loading animation:

@keyframes jump {
  0% { transform: translateY(0); }

  100% { transform: translateY(0); }
}

.loader {
  width: 50px;
  height: 50px;

  border-radius: 50%;
  animation: jump 1s infinite;
}

3. Gradient loading animation

Gradient loading animation is a simple and beautiful loading animation effect, by letting the elements The color changes over a period of time to show the loading process. The following is a code example to implement a gradient loading animation:
