How to quickly master the production method of CSS3 animation effect

CSS3 animation is a commonly used effect in web design. It can add a lively feeling to the web page and improve the user experience. experience. This article will introduce several commonly used CSS3 animation effects production methods, and come with code examples to help readers quickly master the skills of making CSS3 animations.

1. Basic animation

1. Translation

Translation refers to the effect of elements moving along the X-axis or Y-axis. The translation effect can be achieved by using the CSS3 "transform" property and "translate" function in combination with the "animation" property.

Code example:

.box {
    width: 100px;
    height: 100px;
    background-color: red;
    animation: move 2s infinite;
}

@keyframes move {
    0% { transform: translateX(0); }
    50% { transform: translateX(200px); }
    100% { transform: translateX(0); }
}

In the above code, the .box class represents a square box, and the animation is set through the animation attributemove has a duration of 2 seconds and repeats infinitely. @keyframesThe rules define the key frames of the animation, from the initial state to the intermediate state to the end state, corresponding to 0%, 50% and 100% progress respectively. The translation effect along the X-axis is achieved through the transform attribute and the translateX function.

2. Scale

Scale refers to the effect of changing the size of an element. The scaling effect can be achieved by using the CSS3 "transform" property and "scale" function combined with the "animation" property.

Code example:

.box {
    width: 100px;
    height: 100px;
    background-color: red;
    animation: zoom 2s infinite;
}

@keyframes zoom {
    0% { transform: scale(1); }
    50% { transform: scale(2); }
    100% { transform: scale(1); }
}

In the above code, the .box class represents a square box, and the animation is set through the animation attributezoom has a duration of 2 seconds and repeats infinitely. @keyframesThe rules define the key frames of the animation, and the scaling effect is achieved through the transform attribute and the scale function.

2. Transition Animation

Transition animation refers to the effect of an element smoothly changing an attribute when it changes state. By using the CSS3 "transition" attribute and the "hover" pseudo-class, you can achieve the transition effect of elements when the mouse is hovering.

Code example:

.box {
    width: 100px;
    height: 100px;
    background-color: red;
    transition: width 0.5s;
}

.box:hover {
    width: 200px;
}

In the above code, the .box class represents a square box, and the transition time of the element is set to 0.5 through the transition attribute. Second. When the mouse is hovering over .box, the width transitions from the original 100px to 200px.

3. Keyframe animation

Keyframe animation refers to the effect of controlling a series of attribute changes of elements through keyframes. By using CSS3's "@keyframes" rules and "animation" properties, you can achieve more complex animation effects.

Code example:

.box {
    width: 100px;
    height: 100px;
    background-color: red;
    animation: move 2s infinite;
}

@keyframes move {
    0% { transform: translateX(0); opacity: 1; }
    50% { transform: translateX(200px); opacity: 0.5; }
    100% { transform: translateX(0); opacity: 1; }
}

The .box class in the above code is the same as the previous example, and the animation is set through the animation attributemove has a duration of 2 seconds and repeats infinitely. @keyframes Rules define the key frames of animation, set the style changes of elements at different points in time, and can change multiple attributes at the same time, such as transform and opacity .

Through the above code examples, you can see that the production method of CSS3 animation is relatively simple. You only need to master a few basic properties and key frame writing to create rich and diverse animation effects. In actual use, it can also be combined with JavaScript to achieve more complex and advanced animation effects. I hope this article will be helpful to readers and help them quickly master how to create CSS3 animation effects.
