使嵌套div全屏

Question

知道如何将缩略图div拉伸为全屏？我已经尝试了几种方法，最接近我想要的输出是通过使用隐藏div的内容设置父div的innerHTML和类容器，但我仍然需要还原它并添加一些动画变化如此突然。基本上我希望Thumbnail div在Y轴上旋转，在其背面可以找到一些信息。完成Y旋转后，我希望它全屏显示（如弹出窗口）并有一个X按钮关闭并使一切恢复正常。

下面是HTML，CSS和JS（没有添加整个HTML，这将是多余的）

Answer 1

TLDR;）

您只需将元素的SELECT *和width分别设置为height和100vw。

演示：

＆＃13;

＆＃13;

100vh

＆＃13;

document.querySelector("div").addEventListener("click", function(){
  this.classList.toggle("active");
});

＆＃13;

div {
  background-color:aliceblue;
  border:1px solid black;
  box-sizing:border-box;
  position:absolute;
  left:50%;
}

div.active {
  width:100vw;
  height:100vh;
  position:absolute;
  top:0;
  left:0;
}

＆＃13;
