CSS3 animation-timing-function 屬性
定義和用法
animation-timing-function：指定動畫速度曲線。
速度曲線定義動畫從一套 CSS 樣式變?yōu)榱硪惶姿玫臅r間。
速度曲線用于使變化更為平滑。

語法
animation-timing-function: linear|ease|ease-in|ease-out|cubic-bezier(n,n,n,n);| 值 | 描述 | 測試 |
|---|---|---|
| linear | 動畫從開始到結(jié)束具有相同的速度。 | 測試 |
| ease | 動畫有一個緩慢的開始，然后快，結(jié)束慢。 | 測試 |
| ease-in | 動畫有一個緩慢的開始。 | 測試 |
| ease-out | 動畫結(jié)束緩慢。 | 測試 |
| ease-in-out | 動畫具有緩慢的開始和慢的結(jié)束。 | 測試 |
| cubic-bezier(n,n,n,n) | 在立方貝塞爾函數(shù)中定義速度函數(shù)。 可能的值是從0到1的數(shù)字值。 |
提示: 請試著在下面的"嘗試一下"功能中使用不同的值。

實(shí)例
從開始到結(jié)束以相同的速度播放動畫:
animation-timing-function:linear;
-webkit-animation-timing-function:linear; /* Safari and Chrome */
-webkit-animation-timing-function:linear; /* Safari and Chrome */

實(shí)例
為了更好地理解不同的定時函數(shù)值，這里提供了設(shè)置五個不同值的五個不同的 div 元素：
/* W3C and Opera: */
#div1 {animation-timing-function: linear;}
#div2 {animation-timing-function: ease;}
#div3 {animation-timing-function: ease-in;}
#div4 {animation-timing-function: ease-out;}
#div5 {animation-timing-function: ease-in-out;}
/* Firefox: */
#div1 {-moz-animation-timing-function: linear;}
#div2 {-moz-animation-timing-function: ease;}
#div3 {-moz-animation-timing-function: ease-in;}
#div4 {-moz-animation-timing-function: ease-out;}
#div5 {-moz-animation-timing-function: ease-in-out;}
/* Safari and Chrome: */
#div1 {-webkit-animation-timing-function: linear;}
#div2 {-webkit-animation-timing-function: ease;}
#div3 {-webkit-animation-timing-function: ease-in;}
#div4 {-webkit-animation-timing-function: ease-out;}
#div5 {-webkit-animation-timing-function: ease-in-out;}
#div1 {animation-timing-function: linear;}
#div2 {animation-timing-function: ease;}
#div3 {animation-timing-function: ease-in;}
#div4 {animation-timing-function: ease-out;}
#div5 {animation-timing-function: ease-in-out;}
/* Firefox: */
#div1 {-moz-animation-timing-function: linear;}
#div2 {-moz-animation-timing-function: ease;}
#div3 {-moz-animation-timing-function: ease-in;}
#div4 {-moz-animation-timing-function: ease-out;}
#div5 {-moz-animation-timing-function: ease-in-out;}
/* Safari and Chrome: */
#div1 {-webkit-animation-timing-function: linear;}
#div2 {-webkit-animation-timing-function: ease;}
#div3 {-webkit-animation-timing-function: ease-in;}
#div4 {-webkit-animation-timing-function: ease-out;}
#div5 {-webkit-animation-timing-function: ease-in-out;}

實(shí)例
與上例相同，但是通過 cubic-bezier 函數(shù)來定義速度曲線：
/* W3C and Opera: */
#div1 {animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Firefox: */
#div1 {-moz-animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-moz-animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-moz-animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-moz-animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-moz-animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Safari and Chrome: */
#div1 {-webkit-animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-webkit-animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-webkit-animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-webkit-animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-webkit-animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
#div1 {animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Firefox: */
#div1 {-moz-animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-moz-animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-moz-animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-moz-animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-moz-animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Safari and Chrome: */
#div1 {-webkit-animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-webkit-animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-webkit-animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-webkit-animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-webkit-animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
