Bootstrap Carousel Full Screen

I am trying to get the image in the bootstrap carousel to show full screen but haven't been able to figure it out, I've been working on this for awhile and am totally stuck. Right now I have just one image, but I will add more once it works...

Solution 1:

Update Bootstrap 4

Bootstrap 4 has utility classes that make it easier to create a full screen carousel. For example, use the min-vh-100 class on the carousel-item content...

<div class="carousel slide" data-ride="carousel">
      <div class="carousel-inner bg-info" role="listbox">
            <div class="carousel-item active">
                <div class="d-flex align-items-center justify-content-center min-vh-100">
                    <h1 class="display-1">ONE</h1>
                </div>
            </div>
      </div>
</div>

Full screen carousel demo

This works to make the carousel items full screen, but carousel items that contain images or videos that have a specific size & aspect ratio require further consideration.

Since the viewport h/w ratio is likely to be different than the image or video h/w ratio, usually background images or object-fit are commonly used to size images and videos to "full screen". For videos, use the Bootstrap responsive embed classes as needed for the video ratio (21:9, 19:9, etc...).

Original answer (Bootstrap 3)

Make sure the img inside the carousel item is set to height and width 100%. You also have to make sure the carousel and any of the .item containers (html,body) are 100%...

html,body{height:100%;}
.carousel,.item,.active{height:100%;}
.carousel-inner{height:100%;}

Boostrap 3 Full Screen Carousel Demo

Here's an example for Bootstrap 3.x: http://www.codeply.com/go/2tVXo3mAtV

Solution 2:

This is how I did it. This makes the images in the slideshow take up the full screen if it´s aspect ratio allows it, othervice it scales down.

.carousel {
    height: 100vh;
    width: 100%;
    overflow:hidden;
}
.carousel .carousel-inner {
    height:100%;    
}

To allways get a full screen slideshow, no matter screen aspect ratio, you can also use object-fit: (doesn´t work in IE or Edge)

.carousel .carousel-inner img {
    display:block;
    object-fit: cover;
}

Solution 3:

I found an answer on the startbootstrap.com. Try this code:

CSS

html,
body {
    height: 100%;
}

.carousel,
.item,
.active {
    height: 100%;
}


.carousel-inner {
    height: 100%;
}

/* Background images are set within the HTML using inline CSS, not here */

.fill {
    width: 100%;
    height: 100%;
    background-position: center;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    background-size: cover;
    -o-background-size: cover;
}

footer {
    margin: 50px 0;
}

HTML

   <div class="carousel-inner">
        <div class="item active">
            <!-- Set the first background image using inline CSS below. -->
            <div class="fill" style="background-image:url('http://placehold.it/1900x1080&text=Slide One');"></div>
            <div class="carousel-caption">
                <h2>Caption 1</h2>
            </div>
        </div>
        <div class="item">
            <!-- Set the second background image using inline CSS below. -->
            <div class="fill" style="background-image:url('http://placehold.it/1900x1080&text=Slide Two');"></div>
            <div class="carousel-caption">
                <h2>Caption 2</h2>
            </div>
        </div>
        <div class="item">
            <!-- Set the third background image using inline CSS below. -->
            <div class="fill" style="background-image:url('http://placehold.it/1900x1080&text=Slide Three');"></div>
            <div class="carousel-caption">
                <h2>Caption 3</h2>
            </div>
        </div>
    </div>
