Twitter Bootstrap carousel different height images cause bouncing arrows

Question

I\'ve been using Bootstrap\'s carousel class and it has been straightforward so far, however one problem I\'ve had is that images of different heights cause the arrows to bo

Answer 1

It looks like bootstrap less/CSS forces an automatic height to avoid stretching the image when the width has to change to be responsive. I switched it around to make the width auto and fix the height.

<div class="item peopleCarouselImg">
  <img src="http://upload.wikimedia.org/...">
  ...
</div>

I then define img with a class peopleCarouselImg like this:

.peopleCarouselImg img {
  width: auto;
  height: 225px;
  max-height: 225px;
}

I fix my height to 225px. I let the width automatically adjust to keep the aspect ratio correct.

This seems to work for me.

You can also use this code to adjust to all carousel images.

.carousel-item{
    width: 100%; /*width you want*/
    height: 500px; /*height you want*/
    overflow: hidden;
}
.carousel-item img{
    width: 100%;
    height: 100%;
    object-fit: cover;
}

Answer 3

The solution given earlier leads to a situation where images may be too small for the carousel box. A proper solution to the problem of bumping controls is to override Bootstraps CSS.

Original code:

.carousel-control {
top: 40%;
}

Override the variable with a fixed value inside your own stylesheet (300px worked in my design):

.carousel-control {
top: 300px;
}

Hopefully this will solve your problem.

Answer 4

Here is the solution that worked for me; I did it this way as the content in the carousel was dynamically generated from user-submitted content (so we could not use a static height in the stylesheet) - This solution should also work with different sized screens:

function updateCarouselSizes(){
  jQuery(".carousel").each(function(){
    // I wanted an absolute minimum of 10 pixels
    var maxheight=10; 
    if(jQuery(this).find('.item,.carousel-item').length) {
      // We've found one or more item within the Carousel...
      jQuery(this).carousel(); // Initialise the carousel (include options as appropriate)
      // Now we iterate through each item within the carousel...
      jQuery(this).find('.item,.carousel-item').each(function(k,v){ 
        if(jQuery(this).outerHeight()>maxheight) {
          // This item is the tallest we've found so far, so store the result...
          maxheight=jQuery(this).outerHeight();
        }
      });
      // Finally we set the carousel's min-height to the value we've found to be the tallest...
      jQuery(this).css("min-height",maxheight+"px");
    }
  });
}

jQuery(function(){
  jQuery(window).on("resize",updateCarouselSizes);
  updateCarouselSizes();
}

Technically this is not responsive, but for my purposes the on window resize makes this behave responsively.

Answer 5

 .className{
 width: auto;
  height: 200px;
  max-height: 200px;
   max-width:200px
   object-fit: contain;
}

Include this JavaScript in your footer (after loading jQuery):

$('.item').css('min-height',$('.item').height());
