动画div不会隐藏在父级之下

Question

火箭我试图给出无限动画like this，并不像示例那样隐藏在父div之下。火箭只是在Y轴上改变并覆盖所有其他元素。项目代码（jsfiddle）：

＆＃13;

＆＃13;

var rocket = document.querySelector('#rocket');

rocket.addEventListener('click', function() {

    this.classList.toggle('clicked');

  })

＆＃13;

Answer 1

首先要做的是：你的JS中存在语法错误。

其次，我为你做了这个代码：http://codepen.io/anon/pen/EaQjdP

我想我知道你正在尝试做什么，我认为它不会起作用。这是第一个（次要）问题：SVG元素按照它们出现在SVG标记中的顺序绘制。因此，您的<circle>元素将始终位于火箭之下。

第二个问题是，您的<circle>元素描述了您想要显示的区域，而不是您要隐藏的区域。

如果您想使用<circle>元素，建议您查看SVG clipping and masking。您的另一个选择是将<svg>元素缩小到您的圈子的大小并使用border-radius: 50%; overflow: hidden; border: 5px solid white;。
