css - TranslateX 一个对象并保持最终位置

Question

我用 CSS transform-translateX 编写了一个测试。动画有效，但对象不保持最终位置，返回到原始位置。

如何保持最终位置？

这里是 CSS:

@-webkit-keyframes mover {
    0% { -webkit-transform: translateX(0); }
    100% { -webkit-transform: translateX(300px); }
} 
@-moz-keyframes mover {
    0% { -moz-transform: translateX(0); }
    100% { -moz-transform: translateX(300px); }
} 
@-o-keyframes mover {
    0% { -o-transform: translateX(0); }
    100% { -o-transform: translateX(300px); }
} 
@keyframes mover {
    0% { transform: translateX(0); }
    100% { transform: translateX(300px); }
}

#box {
    position: relative;
    top: 20px;
    left: 20px;
    width: 50px;
    height: 50px;
    background-color: #666;
}

.box-mover {
    -webkit-animation: mover 2s ease-in-out;
    -moz-animation: mover 2s ease-in-out;
    -o-animation: mover 2s ease-in-out;
    animation: mover 2s ease-in-out;
}

感谢您对此的任何帮助。

Answer 1

添加 forwards 关键字。 DEMO

.box-mover {
    -webkit-animation: mover 2s ease-in-out forwards;
    -moz-animation: mover 2s ease-in-out forwards;
    -o-animation: mover 2s ease-in-out forwards;
    animation: mover 2s ease-in-out forwards;
}

这将设置 animation-fill-mode: 属性。

Forwards - The target will retain the computed values set by the last keyframe encountered during execution. The last keyframe encountered depends on the value of animation-direction and animation-iteration-count:
