CSS3 transition-timing-function 属性

实例

以相同的速度从开始到结束的过渡效果:

  1. div
  2. {
  3. transition-timing-function: linear;
  4. -moz-transition-timing-function: linear; /* Firefox 4 */
  5. -webkit-transition-timing-function: linear; /* Safari 和 Chrome */
  6. -o-transition-timing-function: linear; /* Opera */
  7. }

浏览器支持


IE Firefox Chrome Safari Opera
ie firefox chrome safari opera

Internet Explorer 10、Firefox、Opera 和 Chrome 支持 transition-timing-function 属性。

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

注释:Internet Explorer 9 以及更早版本的浏览器不支持 transition-timing-function 属性。

定义和用法

transition-timing-function 属性规定过渡效果的速度曲线。

该属性允许过渡效果随着时间来改变其速度。

默认值: ease
继承性: no
版本: CSS3
JavaScript 语法: object.style.transitionTimingFunction="linear"

语法

  1. transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-
    bezier(n,n,n,n);
描述
linear 规定以相同速度开始至结束的过渡效果(等于 cubic-bezier(0,0,1,1))。
ease 规定慢速开始,然后变快,然后慢速结束的过渡效果(cubic-bezier(0.25,0.1,0.25,1))。
ease-in 规定以慢速开始的过渡效果(等于 cubic-bezier(0.42,0,1,1))。
ease-out 规定以慢速结束的过渡效果(等于 cubic-bezier(0,0,0.58,1))。
ease-in-out 规定以慢速开始和结束的过渡效果(等于 cubic-bezier(0.42,0,0.58,1))。
cubic-bezier(n,n,n,n) 在 cubic-bezier 函数中定义自己的值。可能的值是 0 至 1 之间的数值。

提示:请在实例中测试不同的值,这样可以更好地理解它们的工作原理。

实例

实例 1

为了更好地理解不同的函数值,请看下面带有五个不同值的五个不同的 div 元素:

  1. #div1 {transition-timing-function: linear;}
  2. #div2 {transition-timing-function: ease;}
  3. #div3 {transition-timing-function: ease-in;}
  4. #div4 {transition-timing-function: ease-out;}
  5. #div5 {transition-timing-function: ease-in-out;}
  6. /* Firefox 4: */
  7. #div1 {-moz-transition-timing-function: linear;}
  8. #div2 {-moz-transition-timing-function: ease;}
  9. #div3 {-moz-transition-timing-function: ease-in;}
  10. #div4 {-moz-transition-timing-function: ease-out;}
  11. #div5 {-moz-transition-timing-function: ease-in-out;}
  12. /* Safari and Chrome: */
  13. #div1 {-webkit-transition-timing-function: linear;}
  14. #div2 {-webkit-transition-timing-function: ease;}
  15. #div3 {-webkit-transition-timing-function: ease-in;}
  16. #div4 {-webkit-transition-timing-function: ease-out;}
  17. #div5 {-webkit-transition-timing-function: ease-in-out;}
  18. /* Opera: */
  19. #div1 {-o-transition-timing-function: linear;}
  20. #div2 {-o-transition-timing-function: ease;}
  21. #div3 {-o-transition-timing-function: ease-in;}
  22. #div4 {-o-transition-timing-function: ease-out;}
  23. #div5 {-o-transition-timing-function: ease-in-out;}

实例 2

与上例相同,但通过 cubic-bezier 来规定速度曲线:

  1. #div1 {transition-timing-function: cubic-bezier(0,0,1,1;}
  2. #div2 {transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
  3. #div3 {transition-timing-function: cubic-bezier(0.42,0,1,1);}
  4. #div4 {transition-timing-function: cubic-bezier(0,0,0.58,1);}
  5. #div5 {transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
  6. /* Firefox 4: */
  7. #div1 {-moz-transition-timing-function: cubic-bezier(0,0,0.25,1);}
  8. #div2 {-moz-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
  9. #div3 {-moz-transition-timing-function: cubic-bezier(0.42,0,1,1);}
  10. #div4 {-moz-transition-timing-function: cubic-bezier(0,0,0.58,1);}
  11. #div5 {-moz-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
  12. /* Safari and Chrome: */
  13. #div1 {-webkit-transition-timing-function: cubic-bezier(0,0,1,1;}
  14. #div2 {-webkit-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
  15. #div3 {-webkit-transition-timing-function: cubic-bezier(0.42,0,1,1);}
  16. #div4 {-webkit-transition-timing-function: cubic-bezier(0,0,0.58,1);}
  17. #div5 {-webkit-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
  18. /* Opera: */
  19. #div1 {-o-transition-timing-function: cubic-bezier(0,0,1,1;}
  20. #div2 {-o-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
  21. #div3 {-o-transition-timing-function: cubic-bezier(0.42,0,1,1);}
  22. #div4 {-o-transition-timing-function: cubic-bezier(0,0,0.58,1);}
  23. #div5 {-o-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
