如何在我的div的右侧制作悬停盒？

Question

我试图修改this  代码，因此框将滑动到框的左侧。 我在想我应该在课堂上更改.overlay right: 0;到right: 100%;，但它没有做任何事情。看起来应该是 另外当盒子向右滑动并且我将鼠标悬停在盒子上时，我该怎么办？我的盒子一直停留，直到我移开鼠标，我该如何解决？

当我向右侧做动画时，这是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%);
}
