How CSS3 animation function helps you achieve creative design and dynamic display

Introduction:
In modern web design, animation is a very important element that can Make the website more attractive and enhance the user experience. The CSS3 animation feature provides a simple and lightweight way to achieve animation effects without using any JavaScript libraries or plugins. This article will introduce some basic concepts of CSS3 animation functions and provide code examples to help you understand how to use CSS3 animation functions to achieve creative design and dynamic display.

1. Basic concepts of CSS3 animation

1. Properties: You can use the animation property in CSS3 to define animation effects. The animation property includes multiple sub-properties, such as animation-name, animation-duration, animation-timing-function, animation-delay, animation-iteration-count, animation-direction, etc. These properties are used to define various aspects of the animation, such as animation name , duration, easing function, delay time, number of repetitions, animation direction, etc.
2. Key frames: In animation, key frames refer to certain specific moments of the animation. By defining key frames, the animation can display different styles at different moments. In CSS3, you can use the @keyframes rule to define keyframes. The @keyframes rule consists of a keyframe selector and a series of style rules, which can define the style of animation on different keyframes.
3. Transition effect: In addition to using key frames to define animation effects, CSS3 also provides the transition attribute to achieve the transition effect of elements. By defining the initial and final states of an element, you can achieve a smooth transition when the element changes state. The transition property includes multiple sub-properties, such as transition-property, transition-duration, transition-timing-function, and transition-delay, which are used to define the properties, duration, easing function, and delay time of the transition.

2. CSS3 animation example demonstration
The following will introduce the sample code of CSS3 animation and transition respectively:

1. CSS3 animation example:

   @keyframes rotate {
    0% { transform: rotate(0deg); }
    100% { transform: rotate(360deg); }
   }
   
   .animation {
    animation-name: rotate; 
    animation-duration: 2s; 
    animation-timing-function: linear;
    animation-iteration-count: infinite;
   }
   
   <div class="animation"></div>

   Copy after login

   The above code defines a keyframe named rotate. From 0% to 100%, the element will rotate 360 ​​degrees linearly around its own center. The .animation class applies this animation and gives it a duration of 2 seconds and an unlimited number of repetitions.

2. CSS3 transition example:

   .transition {
    width: 100px;
    height: 100px;
    background-color: red;
    transition-property: width, height, background-color;
    transition-duration: 1s;
    transition-timing-function: linear;
   }
   
   .transition:hover {
    width: 200px;
    height: 200px;
    background-color: blue;
   }
   
   <div class="transition"></div>

   Copy after login

   The above code defines a .transition class. When the mouse is hovering over the element, the width, The height and background color will smoothly transition to the new state for 1 second.

Conclusion:
CSS3 animation function helps realize creative design and dynamic display, and improves the interactivity and attractiveness of web pages. By using keyframes and transition properties, we can flexibly define the animation effects of elements, thereby presenting richer and more diverse visual effects. I hope the sample code in this article can help you better understand and apply CSS3 animation functions. In actual development, you can flexibly use these features to achieve various creative designs and dynamic display effects, bringing a better user experience to users.
