steps(n, step-position)函数会在两关键帧间插入n帧,并允许跳过开始帧或结束帧。 下面通过改变元素position left属性来演示steps函数及其不同step-position的效果: .jump-start{animation:step-left3ssteps(3,jump-start)infiniteboth;}.jump-end{animation:step-left3ssteps(3,jump-end)infiniteboth;}.jump-none{...
step-end等同于steps(1,end),会忽略最后一步,即从第一步开始执行直到倒数第二步,如果只有两步,那么会一直存在第一步. 引用w3c的一张step的工作机制图 steps 最后再次强调:timing-function 作用于每两个关键帧之间,而不是整个动画
start跳过0%,end跳过100% step-start在变化过程中,都是以下一帧的显示效果来填充间隔动画,所以0% 到 50% 直接就显示了第一只鸟 step-end与上面相反,都是以上一帧的显示效果来填充间隔动画,所以0% 到 50% 直接就显示了第三只鸟 然后思考下,此时我们设置成start,小鸟会是怎样的呢? 答案是: start:进入页面...
step-start:等同于 steps(1, start) step-end:等同于 steps(1, end) steps(<integer>[, [ start | end ] ]?):接受两个参数的步进函数。第一个参数必须为正整数,指定函数的步数。第二个参数取值可以是start或end,指定每一步的值发生变化的时间点。第二个参数是可选的,默认值为end。 cubic-bezier(<num...

step-end等同于steps(1,end):动画分成一步,动画执行时以结尾端点为开始,默认值为end。 看看W3C的规范 transition-timing-function steps第一个参数的错误的理解: steps(5,start) steps() 第一个参数 number 为指定的间隔数,即把动画分为 n 步阶段性展示,估计大多数人理解就是keyframes写的变化次数 例如: @-...

Now let's also try Step Start. Set up the steps to 5. Notice that every time I customize a timing function it will save and appear there. You can see that my custom step end I just used before is also there. Now with the Step Start, you’ll see that the second arm will start ...
Step-start The animation jumps instantly to its final state. So let’s say the animation is set to start at 0px, then move 150px right, and its duration is 4 seconds. Instead of gradually moving to the right over that span of time, it will instantly jump 150px to the right. ...
