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 10、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。該屬性允許過渡效果隨著時間來改變其速度。

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，然後變快，然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 函數中定義自己的值。可能的值是 0 至 1 之間的數值。 |
提示：請在實例中測試不同的值，這樣可以更好地理解它們的工作原理。
實例 1
為了更好地理解不同的函數值，請看下麵帶有五個不同值的五個不同的 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，但通過 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);}
