Achieving a full-screen Navbar and Carousel combination

I am looking to add a navigation bar at the top of my webpage, followed by a carousel that spans the entire remaining screen.

Here is the structure of my navigation bar:

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
          <span class="navbar-toggler-icon"></span>
        </button>

        <div class="collapse navbar-collapse" id="navbarTogglerDemo02">
          <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
                <li class="nav-item active">
                    <a class="nav-link" href="/">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="/artworks">Artworks</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="/collection">Fashion Collection</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="/blog">Blog</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="/about">About me</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="/contact">Contact me</a>
                </li>
            </ul>
          <form class="form-inline my-2 my-lg-0">
                <a class="navbar-brand" href="/">
                    <img src="/images/logo.png" height="30" class="d-inline-block align-top" alt="">
                </a>
          </form>
        </div>
      </nav>

And here is the markup for my carousel:

<div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel" data-interval="5000">
          <ol class="carousel-indicators">
           <!-- Carousel indicators HTML go here -->
          </ol>
          <div class="carousel-inner">
          <!-- Carousel items HTML go here -->

          </div>
          <!-- Previous and Next controls for carousel -->

        </div>

The code snippets for the above components are inspired from Bootstrap but customized for my needs. Can anyone suggest how I can make the carousel take up the entire screen below the navigation bar?

Implement the following CSS code snippet:

.carousel { height: calc(100vh - 56px);}
.carousel-inner,.carousel-item { height: 100%;}
.carousel-item { background-color: #000;}
.carousel-item img { height: 100%; object-fit: cover; object-position: center;}

Answer №2

When Image Ratio Doesn't Match Viewport Ratio, it can be challenging to achieve the desired look without resorting to using background images...

It's important to think about what will happen if the viewport and image ratios are not equal...

  • Should the images extend off screen?
  • Do you want them to resize to fit the screen width or height (while maintaining aspect ratio)?
  • Or should they stretch to fit, resulting in distorted images that lose their aspect ratio?

Solution 1

To make the carousel fill the remaining height below the navbar, use flex-grow:1. Then, clip the sides of the image when they are too wide for the screen (viewport width). This allows the images to maintain their aspect ratio while filling the height.

See a demo here: https://www.codeply.com/p/5QnXTjbOFL

CSS

/* Use flexbox to make active item container fill the height of the viewport */
.carousel-item.active,
.carousel-item-next,
.carousel-item-prev {
    flex: 1 0 100%;
}

/* Adjust transitioning item height */
.carousel-item-next:not(.carousel-item-left),
.active.carousel-item-right,
.carousel-item-prev:not(.carousel-item-right),
.active.carousel-item-left {
    flex: 0 0 0;
}

/* Ensure images fill height and width or get clipped */
.carousel-item {
    background-repeat: no-repeat;
    background-size: cover;
    background-position: center;
}

.img-1 {
    background-image: url(..);
}

.img-2 {
    background-image: url(..);
}

HTML

<div class="container-fluid d-flex min-vh-100 flex-column px-0 justify-content-center">
    <nav class="navbar navbar-expand-md navbar-light bg-light flex-shrink-0">
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbar1">
            <span class="navbar-toggler-icon"></span>
        </button>
        <a class="navbar-brand" href="#">Navbar</a>
        <div class="collapse navbar-collapse" id="navbar1">
            <ul class="navbar-nav">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Link</a>
                </li>
            </ul>
        </div>
    </nav>
    <div id="carouselExampleControls" class="carousel slide flex-fill d-flex flex-column  justify-content-center" data-ride="carousel">
        <div class="carousel-inner flex-fill d-flex flex-column">
            <div class="carousel-item active img-1">
            </div>
            <div class="carousel-item mg-2">
            </div>
        </div>
    </div>
</div>

Solution 2

If you need to use images, it's possible to utilize object-fit without relying on the flexbox approach from Solution 1. By using calc to determine the height of the carousel (minus the Navbar height of 56px), you can prevent a vertical scrollbar...

/* Ensure images fill height and width or get clipped */
.carousel-item > img {
    object-fit: cover;
    height: calc(100vh - 56px);
    width: 100%;
}
