CSS3 transition-timing-function 属性
实例
过渡效果以同样的速度从开始到结束:
transition-timing-function: linear;
-webkit-transition-timing-function: linear; /* Safari and Chrome */
-webkit-transition-timing-function: linear; /* Safari and Chrome */

属性定义及使用说明
transition-timing-function 是 CSS3 中用来指定过渡效果的时间函数的属性。它定义了过渡效果在时间上的变化规律,控制了过渡效果的速度曲线,从而影响了元素从开始到结束过渡过程中的动画效果。
该属性的值可以是下列预定义的时间函数之一:
ease
:默认值,缓慢加速,然后缓慢减速的过渡效果。linear
:匀速过渡效果。ease-in
:缓慢加速的过渡效果。ease-out
:缓慢减速的过渡效果。ease-in-out
:先缓慢加速,再缓慢减速的过渡效果。cubic-bezier(n,n,n,n)
:自定义的贝塞尔曲线函数,通过四个值来定义曲线的控制点,分别对应x1
、y1
、x2
、y2
。
例如,如果你想让过渡效果具有缓慢加速,然后缓慢减速的效果,可以这样写:
.element { transition-timing-function: ease; <p>}如果你想要一个匀速的过渡效果,可以这样写:
.element { transition-timing-function: linear; }
你也可以使用自定义的贝塞尔曲线函数来实现更精细的过渡效果。例如:
.element { transition-timing-function: cubic-bezier(0.42, 0, 0.58, 1); }
这将创建一个自定义的缓慢加速和缓慢减速的效果。你可以调整四个值来调整曲线的形状,以实现特定的过渡效果。
通过调整 transition-timing-function 属性,你可以控制过渡效果的速度和动画效果,从而使你的界面交互更加生动和吸引人。
默认值: | ease |
---|---|
继承: | no |
版本: | CSS3 |
JavaScript 语法: | object.style.transitionTimingFunction="linear" |
语法
transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-bezier(n,n,n,n);
值 | 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。 |

为了更好地理解不同的函数值:这里有五个不同的div元素,用5个不同的值:
#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;}
/* Safari */
#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;}
#div2 {transition-timing-function: ease;}
#div3 {transition-timing-function: ease-in;}
#div4 {transition-timing-function: ease-out;}
#div5 {transition-timing-function: ease-in-out;}
