CSS Animation Tutorial: Teach you step by step how to implement zoom gradient effects

In modern web design, animation effects are one of the important elements to attract user attention and enhance user experience. one. CSS animation is an animation effect based on CSS style attributes. Dynamic effects can be achieved by changing the style attribute values ​​of elements. In this article, we will teach you step by step how to use CSS animation to achieve scaling and gradient effects, along with specific code examples.

1. Create HTML structure

First, we need to create an HTML structure to place the elements that need to be animated. In this example, we create a container that contains a floating circular icon. The HTML code is as follows:

<div class="container">
  <div class="circle"></div>
</div>

2. Add styles

Next, we need to add styles to the container and circular icon. We will use CSS to define the style of the container, including properties such as width, height, and background color. The style of the circular icon will be modified later in the animation. The CSS code is as follows:

.container {
  width: 200px;
  height: 200px;
  background-color: #f1f1f1;
  display: flex;
  justify-content: center;
  align-items: center;
}

.circle {
  width: 60px;
  height: 60px;
  background-color: #ff7f50;
  border-radius: 50%;
}

3. Create animation

Now, we start to create animation effects. We will use keyframes to set up the various stages of animation and apply them to the circular icon. In this example, we will implement a scaling gradient effect, making the circular icon grow from small to large and gradually changing the background color. The CSS code is as follows:

@keyframes scale-effect {
  0% {
    transform: scale(0.5);
    background-color: #ff7f50;
  }
  50% {
    transform: scale(1.5);
    background-color: #87ceeb;
  }
  100% {
    transform: scale(1);
    background-color: #ff7f50;
  }
}

.circle {
  animation: scale-effect 2s infinite;
}

In the above code, we define a keyframe animation called scale-effect. At the 0% stage of the animation, we set the scale of the circle icon to 0.5 and set the background color to orange. At the 50% stage, we increase the zoom to 1.5 and the background color changes to sky blue. Finally, at the 100% stage, we set the scaling back to 1 and the background color returns to orange. We can apply this animation to the circular icon by applying the animation attribute to the .circle class.

4. Complete effect

Now, we have completed the CSS code for the scaling gradient effect. Save the HTML and CSS files, and open the HTML file in your browser, you will see a floating circular icon that constantly scales and changes background color.

Through this tutorial, you learned how to use CSS animation to achieve scaling and gradient effects. In actual web design, you can customize various stages and properties of animation as needed to obtain richer and more interesting animation effects. I hope this tutorial will be helpful to your learning and practice!
