Automatic rotation of elements using CSS3

How to implement automatic rotation in CSS3 requires specific code examples

CSS3 is a powerful style language that allows us to achieve a variety of effects and animations . One of them is auto-rotation, which is the effect that elements can rotate automatically without user action. This article will introduce how to use CSS3 to achieve automatic rotation and provide specific code examples.

First, we need to set an element to rotate. It can be a div, an image, a button, etc. We set a class for this element, such as "rotate".

Next, we need to use CSS3’s @keyframes rule to define the rotation animation. The @keyframes rule allows us to control the animation's state at different keyframes. We can define multiple keyframes and specify the style of elements on different keyframes in the animation.

The following is a simple code example of CSS3 automatic rotation animation:

.rotate {

  animation: spin 5s infinite linear;

}

 

@keyframes spin {

  0% {

    transform: rotate(0deg);

  }

  100% {

    transform: rotate(360deg);

  }

}

Copy after login

In the above code, we define a class named "rotate" and set a Rotating animation. This animation is called "spin" and it loops infinitely over 5 seconds, changing in a linear fashion.

In the @keyframes rule, we define two key frames, which are 0% and 100%. At 0%, the element's rotation angle is 0 degrees; at 100%, the element's rotation angle is 360 degrees. This achieves a complete rotation animation.

To use this animation effect, just apply the class name "rotate" to the element you want to rotate, as shown below:

1

<div class="rotate">这是一个自动旋转的div</div>

Copy after login

The above is a code example of using CSS3 to implement automatic rotation. You can customize the speed and direction of rotation according to your needs, and adjust the percentage and angle values ​​of keyframes. At the same time, you can also apply different rotation effects to different elements by adding different classes.

To summarize, CSS3 provides powerful animation features that allow us to easily achieve a variety of animation effects, including automatic rotation. Using CSS3's @keyframes rule, we can define keyframes and control the style of elements on different keyframes in animations. By adding a class and applying animation to the element, we can achieve the effect of automatic rotation. Hope this article is helpful to you!
