How to size a carousel relative to the viewport size Boostrap 4.1.0

Question

Goals

Make the carousel 60% x 60% of the size of the viewport.
Make all images be the same size as the slideshow.
Make the carousel fluid.

Does anyone know how to implement this? This seems to be a stubborn problem for me.

change my color codes below to suit your needs

/*
Removes white gap between slides - change to base color of slide images
*/
.carousel {
  background:#F5F5F5; 
}

.carousel-item .img-fluid {
  width:60%;
  height: 60%;
}

/* 
anchors are inline so you need it make them block to go full width
*/
.carousel-item a {
  display: block;
  width:60%;
  height: 60%;
}

.carousel-control-prev {
  color:#036;
  margin-left: -.5rem;
  z-index: 10;
}

.carousel-control-next {
  color:#036;
  margin-right: -.5rem;
  z-index: 10;
}

.carousel-control-prev:hover {
  color:#0084FF;
}

.carousel-control-next:hover {
  color:#0084FF;
}

use this if you want to use fontawesome icons for the controls

<a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
<i class="fas fa-chevron-circle-left fa-2x"></i>

<a class="carousel-control-next text-faded" href="#carouselExampleControls" role="button" data-slide="next">
<i class="fas fa-chevron-circle-right fa-2x"></i>

close the controls with for each. I don't know why it's not showing in my code – mlegg Apr 30 '18 at 23:09
Unfortunately the slideshow makes up 100% x 100% of the viewport after using your implementation :/ – srpalo May 01 '18 at 01:31
take out the w-100 in the part where it says – mlegg May 01 '18 at 11:06
After removing w-100, the slidshow's dimensions were correct when the browser window is at full size. However, I need the slideshow to be fluid, and it's dimensions aren't getting smaller when I shrink the size of the viewport. – srpalo May 02 '18 at 18:51

In addition to the css rules below, I also made all images members of Bootstrap's .img-fluid.

html {
  height: 100%;
  width: 100%;
}

body {
  height: 100%;
  width: 100%;
  display: block;
}

.carousel {
  height: 60%;
  width: 60%;
}

.carousel-item {
  display: block;
  width: 100%;
  height: 100%;
}
