transition-timing-function 屬性

以相同的速度從開始到結束的過渡效果：

div
{
transition-timing-function: linear;
-moz-transition-timing-function: linear; /* Firefox 4 */
-webkit-transition-timing-function: linear; /* Safari 和 Chrome */
-o-transition-timing-function: linear; /* Opera */
}

Internet Explorer 十、Firefox、Opera 和 Chrome 支持 transition-timing-function 屬性。

Safari 支持替代的 -webkit-transition-timing-function 屬性。

註釋：Internet Explorer 9 以及更早版本的瀏覽器不支持 transition-timing-function 屬性。

定義和用法:transition-timing-function 屬性規定過渡效果的速度曲線。該屬性容許過渡效果隨着時間來改變其速度。

語法

transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-
bezier(n,n,n,n);

值	描述
linear	規定以相同速度開始至結束的過渡效果（等於 cubic-bezier(0,0,1,1)）。
ease	規定慢速開始，而後變快，而後慢速結束的過渡效果（cubic-bezier(0.25,0.1,0.25,1)）。
ease-in	規定以慢速開始的過渡效果（等於 cubic-bezier(0.42,0,1,1)）。
ease-out	規定以慢速結束的過渡效果（等於 cubic-bezier(0,0,0.58,1)）。
ease-in-out	規定以慢速開始和結束的過渡效果（等於 cubic-bezier(0.42,0,0.58,1)）。
cubic-bezier(n,n,n,n)	在 cubic-bezier 函數中定義本身的值。可能的值是 0 至 1 之間的數值。

提示：請在實例中測試不一樣的值，這樣能夠更好地理解它們的工做原理。

實例 1

爲了更好地理解不一樣的函數值，請看下面帶有五個不一樣值的五個不一樣的 div 元素：

#div1 {transition-timing-function: linear;}
#div2 {transition-timing-function: ease;}
#div3 {transition-timing-function: ease-in;}
#div4 {transition-timing-function: ease-out;}
#div5 {transition-timing-function: ease-in-out;}
/* Firefox 4: */
#div1 {-moz-transition-timing-function: linear;}
#div2 {-moz-transition-timing-function: ease;}
#div3 {-moz-transition-timing-function: ease-in;}
#div4 {-moz-transition-timing-function: ease-out;}
#div5 {-moz-transition-timing-function: ease-in-out;}
/* Safari and Chrome: */
#div1 {-webkit-transition-timing-function: linear;}
#div2 {-webkit-transition-timing-function: ease;}
#div3 {-webkit-transition-timing-function: ease-in;}
#div4 {-webkit-transition-timing-function: ease-out;}
#div5 {-webkit-transition-timing-function: ease-in-out;}
/* Opera: */
#div1 {-o-transition-timing-function: linear;}
#div2 {-o-transition-timing-function: ease;}
#div3 {-o-transition-timing-function: ease-in;}
#div4 {-o-transition-timing-function: ease-out;}
#div5 {-o-transition-timing-function: ease-in-out;}

實例 2

與上例相同，但經過 cubic-bezier 來規定速度曲線：

#div1 {transition-timing-function: cubic-bezier(0,0,1,1;}
#div2 {transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Firefox 4: */
#div1 {-moz-transition-timing-function: cubic-bezier(0,0,0.25,1);}
#div2 {-moz-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-moz-transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-moz-transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-moz-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Safari and Chrome: */
#div1 {-webkit-transition-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-webkit-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-webkit-transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-webkit-transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-webkit-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Opera: */
#div1 {-o-transition-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-o-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-o-transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-o-transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-o-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
