1.Transition function

How to use the transition attribute: transition:property duration timing-function;

The property indicates which property is to be smoothly transitioned, and the duration indicates how long it takes to complete the property. Smooth transition of values, timing-function indicates the method by which smooth transition is performed.

Multiple smooth transition examples:

 1 <!DOCTYPE html> 2 <html lang="zh-CN"> 3 <head> 4     
 <meta http-equiv="content-type" content="text/html; charset=utf-8"> 5    
 <meta http-equiv="x-ua-compatible" content="IE=edge"> 6     
 <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"> 7     
 <title>测试</title> 8 </head> 9 <body>10 <div id="test"></div>11 <style>12     #test{13         
 width: 500px;14         height: 500px;15         background-color: yellow;16         /*css动画*/17         
 transform: rotate(0);18         -webkit-transition: transform 0.5s linear, width 0.5s linear;19         -moz-transition: transform 0.5s linear, width 0.5s linear;20         -ms-transition: transform 0.5s linear, width 0.5s linear;21         -o-transition: transform 0.5s linear, width 0.5s linear;22         transition: transform 0.5s linear, width 0.5s linear;23     }24     #test:hover{25         width: 200px;26         transform: rotate(180deg);27     }28 </style>29 </body>30 </html>

2.animation function

Usage examples:

 1 <!DOCTYPE html> 2 <html lang="zh-CN"> 3 <head> 4     
 <meta http-equiv="content-type" content="text/html; charset=utf-8"> 5     
 <meta http-equiv="x-ua-compatible" content="IE=edge"> 6     
 <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"> 7     
 <title>测试</title> 8 </head> 9 <body>10 <div id="test"></div>11 <style>12 /*animation动画*/13     
 @-webkit-keyframes colorChange {14         0%{15             background-color: deepskyblue;16         }        
 50%{18             
 background-color: red;19         }20         
 100%{21             background-color: deepskyblue;22         }23     }24     
 #test{25         width:500px;26         height: 500px;27         
 background-color: deepskyblue;28     }29     #test:hover{30         animation-name: colorChange;         
 animation-duration: 1s;32         animation-timing-function: linear;33     }34 </style>35 </body>36 
 </html>

Method to implement animation:

Method Change speed of attribute value
linear Change at the same speed at the beginning and end of the animation
ease-in At the beginning of the animation The speed is very slow, and then the speed increases along the curve value
ease-out The animation starts very fast, and then the speed slows down along the curve value
ease The animation starts very slowly, then speeds up along the curve value, and then slows down along the curve value
ease-in-out The animation starts very slowly, then speeds up along the curve value, and then slows down along the curve value
