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 bounce up and down to adjust to the new height    This is the code I m using for my carousel    lt div id  myCarousel  class  carousel slide  gt       lt div class  carousel-inner  gt           lt div class  item active  gt               lt img src  image url 300height   gt               lt div class  carousel-caption  gt                   lt h4 gt     lt  h4 gt                   lt p gt     lt  p gt               lt  div gt           lt  div gt           lt div class  item  gt               lt img src  image url 700height    gt           lt  div gt       lt  div gt       lt  -- Carousel nav -- gt       lt a class  carousel-control left  href   myCarousel  data-slide  prev  gt  amp lsaquo  lt  a gt       lt a class  carousel-control right  href   myCarousel  data-slide  next  gt  amp rsaquo  lt  a gt   lt  div gt    The problem is also illustrated in this jsfiddle  Admittedly not mine  I found this on a separate question while trying to solve this problem    My question is  How can I force the carousel to stay at a fixed height  second thumbnail in the fiddle  and center smaller images while keeping the captions and arrow in a static position relative to the carousel

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

Note that the jQuery solutions that normalize height on here may break with IE   After some testing  with Bootstrap 3  it looks like IE doesn t bother resizing images unless they re actually being rendered  If you make the window smaller  the image of the active item gets resized but the background images preserve their height  so the  tallest  height stays the same   In my case we were only rendering images on these items  and the images were only ever a few pixels off  So I opted to style all of the images with the height of the active image  Everything else gets resized to fit the height  so keep that in mind if your aspect ratios vary a lot       function carouselNormalization             var items       carousel  item             if  items length                function normalizeHeights                     let activeImageHeight   items filter   active   find  img   height                    items each function                           this  find  img   css  height    activeImageHeight    px                                                   normalizeHeights                   window  on  resize orientationchange   function                     items each function                           this  find  img   removeAttr  style                                        normalizeHeights                                          window  on  load   carouselNormalization

Try with this jQuery code that normalize Bootstrap carousel slide heights  x000D   x000D  function carouselNormalization       var items       carousel-example-generic  item      grab all slides     heights         create empty array to store height values     tallest    create variable to make note of the tallest slide    if  items length        function normalizeHeights           items each function       add heights to array         heights push   this  height                     tallest   Math max apply null  heights     cache largest value       items each function               this  css  min-height   tallest    px                         normalizeHeights           window  on  resize orientationchange   function           tallest   0  heights length   0    reset vars       items each function               this  css  min-height    0      reset min-height                 normalizeHeights      run it again                        Wait until all the assets have been loaded so a maximum height     can be calculated correctly      window onload   function       carouselNormalization      x000D   x000D   x000D

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    lt div class  item peopleCarouselImg  gt     lt img src  http   upload wikimedia org      gt         lt  div gt    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

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   gt 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
