I have a grid of cards and when I hover over one card the bottom section of this card expands to show more content.

The problem is that when it expands it pushes all other cards down. Instead, I would like it to layer itself on top of the card that is situated underneath. Here are some images to visualize what I’m talking about.

CodePen Example: https://codepen.io/adrenaline681/pen/qBMqrEy

As you can see here there is empty white space underneath:

And here is an example of how I would like it to be. As you can see, the middle card has just expanded on top of the bottom card without pushing it down:

Here is how the CSS looks like:

.grid {
  display: grid;
  width: 60%;
  margin: 0 auto;
  grid-template-columns: 1fr 1fr 1fr;
  gap: 15px;
}

.card {
   transition: all 0.3s linear;
}

.card:hover {
  transform: scale(1.04)
}

.card:hover .description {
  max-height: 100px;
}
  
.image {
  aspect-ratio: 1.6;
  background-color: #516d9b;
  display: flex; 
  justify-content: center; 
  align-items: center;
}

.title {
  display: flex; 
  justify-content: center; 
  align-items: center;
  height: 100px;
  background-color: #3f8539;
}

.description {
  transition: all 0.3s linear;
  display: flex; 
  justify-content: center; 
  align-items: center;
  max-height: 0;
  overflow: hidden;
  height: 100px;
  background-color: #c99753;
  padding-left: 25px;
}

No need for Codepens here on Stack Overflow. We have snippets!

In this snippet I have made the adjustments to your code to implement the behaviour you are looking for.

.grid {
  display: grid;
  width: 60%;
  margin: 0 auto;
  grid-template-columns: 1fr 1fr 1fr;
  gap: 15px;
}

.card {
  position: relative;
}

.card:hover .description {
  display: block;
  position: absolute;
  top: 100%;
}
  
.image {
  aspect-ratio: 1.6;
  background-color: #516d9b;
  display: flex; 
  justify-content: center; 
  align-items: center;
}

.title {
  display: flex; 
  justify-content: center; 
  align-items: center;
  height: 100px;
  background-color: #3f8539;
}

.description {
  display: none;
  overflow: hidden;
  background-color: #c99753;
  padding-left: 25px;
  z-index: 5;
}

If you don’t care about keeping the transitions, the solution by Brett is simple and works. If you do want the transitions, then you’ll need a way to force the description panel to slide above its subsequent siblings. To do that you can add z-index to the card that is hovered instead of the description.

.grid {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 1rem;
}

.card {
  position: relative;
  transition: transform 0.3s ease-in-out;
}

.card:hover {
  transform: scale(1.04);
  /* push this card above siblings */
  z-index: 100;
}

.card:hover .description {
  max-height: 100%; /* set max-height to 100% */
  padding: 1rem; /* add the padding to top and bottom */
}
  
.image {
  aspect-ratio: 1.6;
  background-color: #516d9b;
}

.title {
  height: 100px;
  background-color: #3f8539;
  padding: 1rem;
}

.description {
  transition: all 0.3s ease-in-out;
  overflow: hidden;
  max-height: 0;
  height: max-content; /* dynamic height */
  background-color: #c99753;
  position: absolute;
  top: 100%;
  padding: 0 1rem; /* add padding left and right */
}


/* not important */

* {
  box-sizing: border-box;
}

body {
  width: 60%;
  min-width: 30rem;
  max-width: 60rem;
  margin: 0 auto;
  font-family: sans-serif;
}

.card > * {
  display: flex; 
  justify-content: center; 
  align-items: center;
  text-align: center;
  user-select: none;
}
