设置完成过渡所需的时间

Question

我对转换属性的工作方式感到困惑。

过渡时间是实际时间吗？

例如：

.panel-left,
.panel-right {
 transition: all ease 30s;
]

你点击播放图片，两边打开

怎么不到30秒2面就打开了？

我会使用不同的转换属性来做到这一点吗？

会以不同的方式完成吗？

用什么css 属性来设置2侧完全打开需要多长时间？

(function iife() {
  "use strict";

  function show(el) {
 
    el.classList.remove("hide");
  }

  function hide(el) {
    el.classList.add("hide");
  }

  function coverClickHandler(evt) {
    const cover = evt.currentTarget;
    hide(cover);
    const curtain = document.querySelector(".curtain");
    curtain.classList.add("slide");
    const thewrap = curtain.parentElement.querySelector(".container");
    show(thewrap);
  }

  const cover = document.querySelector(".jacketa");
  cover.addEventListener("click", coverClickHandler);
}());

Answer 1

两个面板各有 50% 的宽度。但是要打开它们，CSS 将它们分别转换为 -100vw 和 100vw。

所以，基本上，它们向左和向右移动的距离比需要的更远 - 它们在过渡时间结束之前就从视野中消失了。

试试这个实验：将其中一个面板平移更改为 100% - 这意味着其宽度的 100%，而不是容器或视口的宽度。你会看到右面板的移动速度大约是左面板的一半，需要 30 秒才能消失。

.curtain.slide .panel-left {
  transform: translateX(-100vw);
}

.curtain.slide .panel-right {
  transform: translateX(100%);/* CHANGED */
}

我不确定为什么要编写代码以翻译成 100vw 术语 - 'normally' 我会翻译一个元素的完整 (100%) 宽度以使其不可见。那么就很清楚了，transition time就是元素消失所需要的时间。因此，要么更改您的 HTML 以执行上述操作，要么减少您的过渡时间。
