Question

I have trouble creating a carousel in Bootstrap 4 with text centered both horizontally and vertically.

I have created the bootply with a carousel, but the text is ju

Answer 1

Simply you are missing this:

<div class="carousel-caption">

Before the <h1>Text 1</h1> So it's like this:

<div class="carousel-item active">
  <div class="carousel-caption">
    <h1>Text 1</h1>
  </div>
</div>

Answer 2

You can use display: table; and display: table-cell; display along with vertical-align: middle;

.carousel-item {
    display: table;
    text-align: center;
}

.carousel-item h1 {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}

The key here is vertical-align: middle; which works only if a div is a table.

Regarding the horizontal alignment, the text-align: center; goes to .carousel-item. I updated my code.

Answer 3

Change your CSS for h1 into the following:

.carousel-item h1 {
  position: absolute;
  margin: 0;
  color: white;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}

You can use the Bootstrap 4 utility classes (no additional CSS is needed)...
