how to create hover animation on a div

Question

I wanted to create a div which has a background image and a transparent background color over it with some text. When hover, the transparent background color should slide out towards the bottom of the div as shown in the image:

Left block is default. Right block is hover state.

I modified this snippet: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_image_overlay_fade

I modified the provided style to:

<style>
.container {
  position: relative;
  width: 50%;
}

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

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

.container .overlay {
  opacity: 0.75;
}

.container:hover .overlay {
  opacity: 0;
}

.text {
  color: white;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}
</style>
