Creating a half-page Bootstrap Carousel: Steps and Tips

Is there a way to make this Bootstrap 3 carousel half-page? I'm struggling to figure out what adjustments need to be made in order to achieve that. It displays well in a small window, but once I expand it to full screen, the carousel takes over the entire page. How can I ensure that the Bootstrap carousel only takes up half of the page on a full window?

I attempted placing it within a header element, but unfortunately, that did not yield the desired outcome.

<div id="carousel1" class="carousel slide carousel-fade" data-ride="carousel">
  <!--Indicators-->
  ... (carousel code here)
  </ol>
</div>

A recent update has left the carousel displaying as half-screen, however, when increasing the window size, the images become increasingly zoomed in. Utilizing CSS code provided by another user helped me achieve the half-page display for the carousel, yet the image zooming issue persists with window expansion. How can I prevent the images from zooming in as the window size increases?

.carousel-inner{
    height: 50vh;
}

.item img{
    height: 100% !important;
    width:  100% !important;
}

Answer №1

If you are using Bootstrap 4 and want to prevent images from zooming in on smaller screens, you can achieve this by adjusting the height of the carousel items using CSS media queries. It's important to maintain a proportional relationship between the height values set for larger and smaller screens due to differences in viewport dimensions.

Below is a sample code snippet that you can use:

    /* Set carousel item height to half of viewport height */
    
    .carousel-item.active, .carousel-item .view {
        height: 50vh!important;
      }
      .carousel-item.active, .carousel-item  {
        height: 50vh!important;
      }
    
      .carousel-item img {
        object-fit: cover;
        width:100%!important;
        height: 100% !important;
      }
    
      .content h1 {
        font-size: 55px;
      }
      .content h5 {
        font-size: 23px;
        margin-left: 80px;
        margin-right: 80px;
      }
    
      /* RESPONSIVE DESIGN WITH MEDIA QUERIES */
    
    /* Extra small devices (phones, up to 600px) */
    @media only screen and (max-width: 600px) {
        /* Adjust carousel item height for smaller screens */
    
    .carousel-item.active, .carousel-item .view {
        height: 30vh!important;
      }
      .carousel-item.active, .carousel-item  {
        height: 30vh!important;
      }
    
      .carousel-item img {
        object-fit: cover;
        width:100%!important;
        height: 100% !important;
      }
    } 
    
    /* Small devices (portrait tablets and large phones, 600px and above) */
    @media only screen and (min-width: 600px) {
            /* Adjust carousel item height for smaller screens */
    
    .carousel-item.active, .carousel-item .view {
        height: 30vh!important;
      }
      .carousel-item.active, .carousel-item  {
        height: 30vh!important;
      }
    
      .carousel-item img {
        object-fit: cover;
        width:100%!important;
        height: 100% !important;
      }
    
    } 
    
    /* Medium devices (landscape tablets, 768px and above) */
    @media only screen and (min-width: 768px) {
    /* Adjust carousel item height for smaller screens */
    
    .carousel-item.active, .carousel-item .view {
        height: 30vh!important;
      }
      .carousel-item.active, .carousel-item  {
        height: 30vh!important;
      }
    
      .carousel-item img {
        object-fit: cover;
        width:100%!important;
        height: 100% !important;
      }
    } 
    
    /* Large devices (laptops/desktops, 992px and above) */
    @media only screen and (min-width: 992px) {
        /* Adjust carousel item height for larger screens */
    
    .carousel-item.active, .carousel-item .view {
        height: 50vh!important;
      }
      .carousel-item.active, .carousel-item  {
        height: 50vh!important;
      }
    
      .carousel-item img {
        object-fit: cover;
        width:100%!important;
        height: 100% !important;
      }
    
    } 
    
    /* Extra large devices (large laptops and desktops, 1200px and above) */
    @media only screen and (min-width: 1200px) {
        /* Adjust carousel item height for larger screens */
    
    .carousel-item.active, .carousel-item .view {
        height: 50vh!important;
      }
      .carousel-item.active, .carousel-item  {
        height: 50vh!important;
      }
    
      .carousel-item img {
        object-fit: cover;
        width:100%!important;
        height: 100% !important;
      }
    
    }
