html - 如何在 div 的右侧制作悬停框？

Question

我正在尝试修改 this 代码，所以盒子会滑到盒子的左边。我在想我应该改变类 .overlay right: 0; 到 right: 100%;，但它什么也没做。它应该看起来像这样 另外，当我将鼠标悬停在盒子上时，盒子向右滑动时，我的盒子会一直停留，直到我将鼠标移开，我该怎么办？

这是我在右侧制作动画时的 css 代码:

.container {
  position: relative;
  width: 50%;
}

.image {
  display: block;
  width: 100%;
  height: auto;
}

.overlay {
  position: absolute;
  bottom: 0;
  left: 100%;
  right: 0;
  background-color: #008CBA;
  overflow: hidden;
  width: 0;
  height: 100%;
  transition: .5s ease;
}

.container:hover .overlay {
  width: 100%;
}

.text {
  white-space: nowrap; 
  color: white;
  font-size: 20px;
  position: absolute;
  overflow: hidden;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
}

使用此代码在悬停时向左移动叠加层

.overlay {
  position: absolute;
  bottom: 0;
  left: 0; 
  background-color: #008CBA;
  overflow: hidden;
  width: 0;
  height: 100%;
  transition: .5s ease;
}

.container:hover .overlay {
 width: 100%;
 left: -100%;
}

.container {
  position: relative;
  width: 50%;
  float:right;
}

.image {
  display: block;
  width: 100%;
  height: auto;
}

.overlay {
  position: absolute;
  bottom: 0;
  left: 0; 
  background-color: #008CBA;
  overflow: hidden;
  width: 0;
  height: 100%;
  transition: .5s ease;
}

.container:hover .overlay {
  width: 100%;
  left: -100%;
}

.text {
  white-space: nowrap; 
  color: white;
  font-size: 20px;
  position: absolute;
  overflow: hidden;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
}
