Modify carousel configuration in bootstrap 4 [closed]

Navigation
0

I'm using the template below to make a slide, a template in which I got a previous question that I asked and a person helped me by pasting the path, but the slide is too big and I need to decrease the size, I'm finding in the bootstrap the stylo css sheet that contains the .carousel-inner element to make the modifications. 

.slide img {
  width: 100%;
  height: 50%;
}

I made this model that you can control the height of the slider, in the example I put with 30% of the height of the screen.

See in the part of CSS that I left commented on how to adjust. 

.carousel-item {
    overflow: hidden;
    width: 100%;
    height: 30vh; /* aqui vc ajusta a altura do slider */
}
.carousel-item img {
    width: 100%;
    /* transform: translateY(-50%)  habilitar se quiser pocicionar o meio da imagem no slider*/
}
