CSS过渡自动高度不起作用

Jus*_* me 59 css animation css-transitions

我有一个网站,我决定用纯CSS片段替换基于jquery的切换框.当我使用固定高度值进行过渡(CSS的最后一行)时,它运行良好,但是使用该auto值,动画丢失,只有高度变化才有效!

有没有办法使用自动值？我想使用变量文本而不使用脚本.

一个解决方案,如果你只是想使用CSS是转换max-height而不是height将其设置为比它将获得的更大的东西......

这是一个演示

您需要稍微调整转换的速度,但至少这个示例可以让您了解如何完成转换.不要忘记在转换过程中更改属性.从transition: height 0.5s;到transition: max-height 0.5s;.

希望这可以帮助!

  • 最糟糕的例子.如果给出的示例尽可能地将其保持为对主题的最小化将是好的.那里有太多的毛茸茸让我甚至懒得试图弄清楚那里是否有任何价值. (5认同)
  • 这是一个很棒的演示.我只有一个问题:如果你选择而不是max-height:500px更高的值(即10000px),动画会更快(当然是更高的值和恒定的时间).问题,如果你不知道什么是一个好的最大值(导致部分高度可能会高得多).所有部分将不断快速动画.有一点JavaScript需要让真正的部分高,并设置它的最大高度.浏览器不会自己做这件事太烦人了. (4认同)
  • 这仅适用于您打算在零和自动之间转换的情况,而不是自动和自动(即内部内容更改时) (3认同)

您无法为"自动"维度制作动画(不幸的是).我通常采用的方法是设置外部DIV的高度,该外部DIV具有单个子项,这是一种仅用于测量内容高度的无样式DIV.

function growDiv() {
  var growDiv = document.getElementById('grow');
  if (growDiv.clientHeight) {
    growDiv.style.height = 0;
  } else {
    var wrapper = document.querySelector('.measuringWrapper');
    growDiv.style.height = wrapper.clientHeight + "px";
  }
}

你应该使用scaleY.

ul {
  background-color: #eee;
  transform: scaleY(0);    
  transform-origin: top;
  transition: transform 0.3s ease-in-out;
}

或者您可以使用clip来削减名单.

ul {
  clip: rect(auto, auto, 0, auto);
  position: absolute;
  left: 0;
  margin: 0;
  padding: 0;

  color: white;

  • 这不起作用,因为当对象是scaleY(0)时,DOM中仍保留完整高度 (8认同)

很久以前我遇到了这个问题并且需要克服很多困难,但CSS转换不适用于自动值.最后我提出了一个混合解决方案,让css过渡,但用JavaScript改变高度.它会很完美.
