CSS Animation: How to achieve the shaking and scaling effect of elements

In web design, the animation effect of elements can increase the user's visual experience and add vitality to the dull page. . CSS animation is one of the powerful tools to achieve these effects. This article will introduce in detail how to use CSS animation to achieve the dithering and scaling effect of elements, and provide specific code examples for readers' reference.

The jitter zoom effect is a common animation effect that can play an excellent role in user interaction, page loading and other scenarios. It creates vivid, interesting effects by allowing elements to quickly scale and shift at random amounts, combined with appropriate easing. By adjusting the amplitude and frequency of jitter scaling, you can also change the characteristics of the animation according to actual needs to make it more in line with design requirements.

To achieve the jitter scaling effect of elements, we can use CSS keyframe animation (@keyframes) to create a custom animation sequence, and set the animation effects of element scaling and displacement respectively in the sequence. The following is a CSS code example that implements the shake and zoom effect of elements:

@keyframes shake {
  0% {
    transform: scale(1);
  }
  25% {
    transform: scale(1.5) translateX(-5px) translateY(-5px);
  }
  50% {
    transform: scale(1);
  }
  75% {
    transform: scale(0.5) translateX(5px) translateY(5px);
  }
  100% {
    transform: scale(1);
  }
}

.element {
  animation: shake 1s infinite;
}

In the above code, we define a keyframe animation named shake, and achieve the shake and zoom effect by setting styles of different percentages. Specifically, the 0% and 100% states maintain the original size of the element, the 25% and 75% states enlarge and reduce respectively, and use the translateX and translateY attributes for displacement.

Then, we apply this animation to the elements that need to achieve the shake scaling effect by setting the animation attribute and specifying the corresponding animation name (shake), time (1s) and number of cycles (infinite), that is Can achieve dithering scaling effect of elements.

Of course, the above code is just an example. Based on actual needs, you can adjust it according to specific design requirements. For example, you can change the duration of the animation, the easing effect, and the magnitude of the displacement and scaling. It can also be combined with other CSS properties, such as color gradients, transparency changes, etc., to further enrich the animation effect.

In addition to the jitter zoom effect, CSS animation can also achieve many other animation effects, such as rotation, fade in and fade out, sliding, etc. Through the flexible use of CSS animation, you can create rich and diverse page interaction effects, improve user experience, and make web pages more vivid and attractive.

To summarize, by using CSS keyframe animation and corresponding CSS properties, we can achieve the shaking and scaling effect of elements and increase the dynamics and vitality of the page. In actual application, we can adjust the animation parameters according to specific needs to obtain an effect that better meets the design requirements. I hope that the introduction and code examples of this article can help readers make better use of CSS animations and add more creativity and highlights to web design.
