CSS3 realizes bouncing ball animation
|
I usually like to visit the special pages or product release pages of major websites because I can see a lot of cool page effects. The material for this case comes from the release page of Baidu Browser, and the next case "Chameleon Animation" also comes from Baidu Browser. Although I am a loyal user of Google Chrome, I have to say that the special pages and product release pages of well-known brand websites in the domestic Internet industry have all tried their best to make the pages look cool. The key point of this case lies in the rhythm of the ball's bouncing and the layout positioning.
1. Case Knowledge Points 1. Relative and absolute positioning 2. Multiple animation queues 2. Main code 1. HTML code
<div id="wrap">

}}For animations in multiple queues, pay attention to the animation delay. The animation of the next queue will be executed only after the animation of the previous queue is completed. Complete page code
