CSS Animation Guide: Teach you step-by-step how to create flash effects

In today's web design, animation effects have become an important factor in attracting user attention and improving user experience. one. Among them, CSS animation is one of the common methods to achieve various effects. This article will show you how to use CSS to create a stunning sparkle effect and provide specific code examples.

The flash effect can make page elements flash or flash under the light, giving people a lively feeling. The following will demonstrate how to use CSS to achieve this effect through a simple example.

First, create a div element in HTML and give it an ID as a selector for CSS styling. The code is as follows:

Next, in the CSS file, we will use the @keyframes rule to define the animation effect of the flash. The @keyframes rule is used to create animations. You can specify one or more keyframes in the animation and set the style of the keyframes.

@keyframes shine {
  0% { opacity: 0; } // 初始状态设置为透明
  50% { opacity: 1; } // 50%时设置为完全显示
  100% { opacity: 0; } // 结束时再次设置为透明
}

In the above code, we define an animation named "shine", which has three keyframes. The initial state transparency is 0, at 50% the transparency is 1 to fully display, and at 100% the transparency is set to 0 again.

Next, we specify the style for the div element we just created and apply the animation effect to the element. The code is as follows:

#shine-effect {
  width: 100px;  // 设置宽度
  height: 100px;  // 设置高度
  background-color: yellow;  // 设置背景颜色
  animation: shine 2s infinite; // 应用动画效果，2s表示动画持续时间，infinite表示无限循环播放
}

In the above code, we specify the width, height and background color of the div element. We achieve this effect by applying a "shine" animation to the element, using the animation attribute. Here, we set the duration of the animation to 2 seconds and use the infinite keyword to achieve infinite loop playback.

Finally, save the above code as a style.css file and link it to the HTML file. The code is as follows:

Save and load the HTML file, you will see a yellow square with a flashing effect.

You can customize the effect of the flash by changing the parameters in the above code. For example, you can change the width, height, color, etc. of the element, or adjust the duration and number of loops of the animation to achieve different effects.
