CSS3 Chrome 中的过渡故障

CSS3 transition glitch in Chrome

我有一个简单的模式,它在 :checked 输入时打开。在 Firefox 和 IE 中,过渡动画效果很好,但在 Chrome 中,它在检查输入时出现故障(效果不流畅)。

演示 fiddle:JsFiddle

当我删除 visibility: hidden 时,它工作正常,但随后模态框将页面的其余部分挡在它下面 - 无法选择文本,无法单击按钮等。

关于如何在 Chrome 中顺利过渡的任何想法?

请检查fiddle:jsfiddle.net

刚刚添加:

opacity: 0.01;
z-index: -1;

到#test,并在叠加层显示时更改 z-index + 不透明度:

opacity: 0.99;
z-index: 9999999;

所述,我们不能使用 visibility 来制作动画。因此,我使用 opacity 作为 rgba 值传递给背景。

    #test {
        position: fixed;
        top: 0;
        right: 0;
        bottom: 0;
        left: 0;
        width: 100%;
        height: 100%;
        background: rgba(0, 0, 0, 0);
        z-index: -1;
    }
    input#switch:checked ~ #test {
        background: rgba(0, 0, 0, 0.8);
        z-index: 9999999;
    }
    #test > div {
        background: #fff;
        width: 300px;
        height: 100px;
        padding: 30px;
        position: absolute;
        top: 0;
        right: 0;
        bottom: 0;
        left: 0;
        margin: auto;
        transform: perspective(300px) rotateX(-90deg);
        transform-origin: top center;
        transition: 0.4s ease;
    }
    input#switch:checked ~ #test > div {
        transform: none;
    }
    #test > div label {
        background: #000;
        color: #fff;
        display: block;
        text-align: center;
        padding: 8px;
        margin-top: 20px;
        cursor: pointer;
    }
<input id="switch" type="checkbox" name="test-chkbox" />
<label for="switch">Open modal</label>
<div id="test">
    <div>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
        <label for="switch">Close modal</label>
    </div>
</div>

回答

您在模态 div 上声明了 transform: none;。只需定义一个 rotationX,这样您的动画就有起点和终点。这解决了动画问题:

input#switch:checked ~ #test > div {
    transform: rotateX(0deg);
}

#test {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0,0,0,0.8);
  z-index: 9999999;
  visibility: hidden;
}
input#switch:checked ~ #test {
  visibility: visible;
}
#test > div {
  background: #fff;
  width: 300px;
  height: 100px;
  padding: 30px;
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  margin: auto;
  transform: perspective(300px) rotateX(-90deg);
  transform-origin: top center;
  transition: 0.4s ease;
}
input#switch:checked ~ #test > div {
  transform: rotateX(0deg);
}
#test > div label {
  background: #000;
  color: #fff;
  display: block;
  text-align: center;
  padding: 8px;
  margin-top: 20px;
  cursor: pointer;
}
<input id="switch" type="checkbox" name="test-chkbox" />
<label for="switch">Open modal</label>

<div id="test">
    <div>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
    <label for="switch">Close modal</label>
    </div>
</div>
