Divs disappear when using inline-block - html

Question

Trying to create a responsive flip-card gallery using a code I came across here. Everything works great except for when I try to align the flip-cards next to each other (trying to create three cards per row) then they just disappear. I've tried using display: inline-block and a flex-grid, but can't figure out where i'm going wrong.
Thank you!
Here's the intial code:
HTML
<div class="container">
<div class="card-container">
<div class="row">
<div class="col">
<div class="flip-container">
<div class="flipper">
<div class="front">
<div class="inner"><img src="image1.jpg" style="height: 100%;"></div>
</div>
<div class="back">
<div class="inner">Back</div>
</div>
</div>
</div>
</div>
</div>
<div class="card-container">
<div class="row">
<div class="col">
<div class="flip-container">
<div class="flipper">
<div class="front">
<div class="inner"><img src="metalcard.jpg" style="height: 100%;"></div>
</div>
<div class="back">
<div class="inner">Back</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
<div class="card-container">
<div class="row">
<div class="col">
<div class="flip-container">
<div class="flipper">
<div class="front">
<div class="inner"><img src="image3.jpg" style="height: 100%;"></div>
</div>
<div class="back">
<div class="inner">Back</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
CSS:
.container {
margin: 0 auto;
max-width: 1200px;
padding: 0 1rem;
display: inline-block;
}
.card-container{
width: 25%; /* Adjust the target width*/
}
.flip-container {
position: relative;
perspective: 1000px;
}
/* flip the pane when hovered */
.flip-container:hover .flipper, .flip-container.hover .flipper {
transform: rotateY(180deg);
}
.flip-container, .front, {
width: 100%;
height: 170px;
}
.flip-container,.back {
height: 190px;
width: 100%;
}
.flipper {
transition: 0.9s;
transform-style: preserve-3d;
position: relative;
}
.front, .back {
backface-visibility: hidden;
position: absolute;
top: 0;
left: 0;
}
.front {
background: rgba(0,0,0,0.05);
z-index: 2;
/* for firefox 31 */
transform: rotateY(0deg);
}
/* back, initially hidden pane */
.back {
background: #00ccff;
transform: rotateY(180deg);
}
