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

Introduction:
In web design, animation effects are one of the important means to improve user experience. As one of the commonly used tools for front-end developers, CSS animation can easily achieve various animation effects. This article will show you how to use CSS to create a simple blinking effect, with specific code examples.

1. HTML structure:
First, we need to create an HTML page and set the required CSS properties. The following is an example HTML structure:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>CSS动画指南</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div class="box"></div>
</body>
</html>

Copy after login

2. CSS style:
Next, add the following style in the style.css file:

.box {
    width: 100px;
    height: 100px;
    background-color: red;
    animation: blink 1s infinite;
}

@keyframes blink {
    from {
        opacity: 1;
    }
    to {
        opacity: 0;
    }
}

Copy after login

3. Parsing:
In the above code, we first create a box div element to display the flickering effect. Then, in the CSS style, we set the width, height, and background color of the element, and use the animation attribute to specify the blink effect's name (blink), duration (1 second), and play count (infinite loop).

Next, we defined an animation named blink through the @keyframes rule. At the beginning of the animation (from), we set the element's transparency to 1, which means it is fully visible. At the end state of the animation (to), we set the transparency of the element to 0, which means it is completely hidden.

Finally, we apply the animation to the box element to achieve a flickering effect.

4. Effect display:
Save the file and open the HTML page in the browser, you will see a flashing effect like a breathing light.

5. Expansion:
If you want to modify the speed of the flashing effect, you can adjust the duration of the animation attribute (1s). For example, changing it to 0.5s will speed up the flashing. And if you want to change the color of the flashing effect, just change the background-color attribute of the box element to the color value you want.

6. Summary:
Through the guide in this article, you learned how to use CSS to create a simple flashing effect. Using CSS animations, you can add more interactivity and vividness to web pages and improve user experience. I hope this article is helpful to you.
