Fill out the background color-CodePudding

Goal:
Mouse hovering over the picture and its area, the title and content will raise up. The contents background and height should go to the bottom of the area.

Problem:
The title and contents background don't go all the way down to the button.
I don't know how to do.
Please take a look at the picture for visual communication.

JSBin:

.cards {
  margin: 0 auto;
  display: grid;
  grid-gap: 5px;
}

.card {
  width: 100%;
  min-height: 100px;
  background-color: #e6e6e6;
  text-align: center;
  border: 1px solid white;
  transition: border 1s;
  position: relative;
}

.card:hover {
  border: 1px solid black;
}

.card .wrapper {
  bottom: 0;
  position: absolute;
  transition: all .3s ease;
  width: 100%;
}

.card:hover .wrapper {
  bottom: 30px;
  transform: translateY(-50%)
}

.cardTitle {

Using the technic from this answer:

Removed following style because it's causing the height problem.

.card:hover .wrapper {
  bottom: 30px;
  transform: translateY(-50%);
}

Instead of changing the visibility on .cardText I change the max-height:

.cardText {
  background-color: #fff;
  height: 0;
  opacity: 0;
  max-height: 0;
}

.card:hover .cardText {
  height: 100%;
  opacity: 1;
  max-height: 500px;
  transition: max-height 0.25s ease-in;
}

The idea is to put the image inside it's own wrapper that will shrink from the bottom up (from 100% to 70% in this example). Of course, all overflow hidden.

.cards {
  margin: 0 auto;
  display: grid;
  grid-gap: 5px;
}

.card {
  width: 100%;
  min-height: 100px;
  background-color: #e6e6e6;
  text-align: center;
  border: 1px solid white;
  transition: border 1s;
  position: relative;
}

.card:hover {
  border: 1px solid black;
}

.card .wrapper {
  bottom: 0;
  position: absolute;
  transition: all .3s ease;
  width: 100%;
}

.card:hover .wrapper {
  bottom: 30px;
  transform: translateY(-50%)
}

.cardTitle {
  width: 100%;
  margin-top: -4px;
  color: white;
  background-color: grey;
  font-size: xx-large;
}

.cardText {
  background-color: #fff;
  height: 0;
  opacity: 0;
  visibility: hidden;
}

.card:hover .cardText {
  height: 100%;
  opacity: 1;
  visibility: visible;
}

.responsive {
  width: 300px;
}

.img-wrapper {
  height: 100%;
  position: relative;
  overflow: hidden;
  transition: all .3s ease;
}

.card:hover .img-wrapper {
  height: 70%;
}

.card {
  overflow: hidden;
}
