CSS3 shows wonderful animation effects css3 animation properties_html/css_WEB-ITnose

The hot CSS3 has undoubtedly attracted the attention of many front-end developers. However, the animation properties in CSS3 are the main signature of the new features. Speaking of the animation properties of CSS3, people have to think of this Three attributes: Transform?Transition?Animation. Although the transform attribute seems to be able to achieve animation effects, its essence is actually static. To put it bluntly, it is actually a graphic deformation tool; while the transition attribute is a simple animation attribute, which is very simple to operate; here I will mainly introduce it to you. Animations attribute, this is a real animation attribute. Although the official does not introduce it too much, it just briefly explains that this attribute is an extension of the transition attribute, but its function is very powerful. Animations can define multiple key frames and define each key. Property values ​​of elements in the frame to achieve complex animation effects. So what kind of animation can Animation make? It can be said that as long as you are creative and you can toss, then everything is possible.

I believe everyone is familiar with this attribute, so I won’t introduce too much basic knowledge. If you don’t know much about it, you can look for basic knowledge on the Internet. There is a lot of relevant information available.

Here I will tell you about a very important tag: keyframes. How to move animation? It all depends on it. The basic principle of keyframes is similar to the timeline and keyframes of flash, so rich animations can be produced. Take a look at the simple example:

@keyframes demos{

from{transform:translate(0, 0);}

20%{transform:translate(20, 20 );}

40%{transform:translate(40,0);}

60%{transform:translate(60,20);}

80%{ transform:translate(80, 0);}

to{transform:translate(100, 20);}

}

The above example sets a file called " demos" animation, in which from, 20%, 40%, 60%, 80%, and to respectively represent the corresponding attribute effects at different points in time (from and to can be represented by 0% and 100%, please note is 0% and cannot be abbreviated to 0). It can be seen that we can set corresponding attribute effects at multiple time points, which greatly enriches our animation effects. At any two points in time, Animation will automatically calculate the intermediate transition effect. At the same time, we can also control the time period by setting Animation to achieve high-quality animation. Compared with flash, the animation properties of Animation are not inferior. The biggest advantage is that it is simple to create. With just a few lines of code, rich animations can be rendered, which is beyond the reach of flash.

The link above is to organize a sample page for you. Some of the examples are made by myself, and some are collected from the Internet. The purpose is to show you more and more exciting animation effects so that you can Learn more. If you have a good idea, please share it with us and add it to this page. This sample page will also be continuously updated from time to time to let more people know that because of CSS3, everything is possible with animation. possible.
