Answer 1

With owl carousel version 2.1.1 and CSS3 Flexbox, just add the style:

.owl-carousel .owl-stage {
  display: flex;
  align-items: center;
}

See the snippet:

$( document ).ready( function() {
  $( '.owl-carousel' ).owlCarousel({
     autoplay: true,
     margin: 2,
     loop: true,
     responsive: {
        0: {
           items:1
        },
        200: {
           items:3
        },
        500: {
           items:4
        }
     }
  });
});

.owl-carousel .owl-stage {
  display: flex;
  align-items: center;
}

.owl-carousel .caption {
  text-align: center;
}

1. The Owl Carousel creates additional blocks within your layout. To add CSS properties correctly, you need to work with this HTML structure:

   <div id="owl-demo" class="owl-carousel owl-theme">
     <div class="owl-wrapper-outer">
       <div class="owl-wrapper">
         <div class="owl-item">
           <div>
             <img src="" alt="">
           </div>
         </div>
         <div class="owl-item">
           <div>
             <img src="" alt="">
           </div>
         </div>
       </div>
     </div>
   </div>
   

2. Moreover the carousel adds a style attribute to all blocks. For example, a block with the .owl-wrapper class receives the display property with the value of block. So you have to use an !important declaration in your CSS.

3. To obtain a horizontal alignment, you can simply add text-align: center; property to each .owl-item > div.

4. To align vertically, you can turn the carousel items in table cells. But do not forget to cancel the float property for them.

Let us arrange all of the changes as a new .owl-centered class. Please check the result:

$("#owl-example").owlCarousel({
  navigation: true
});

@import url('//cdnjs.cloudflare.com/ajax/libs/owl-carousel/1.3.3/owl.carousel.min.css');
@import url('//cdnjs.cloudflare.com/ajax/libs/owl-carousel/1.3.3/owl.theme.min.css');

.owl-centered .owl-wrapper {
  display: table !important;
}
.owl-centered .owl-item {
  display: table-cell;
  float: none;
  vertical-align: middle;
}
.owl-centered .owl-item > div {
  text-align: center;
}

<div id="owl-example" class="owl-carousel owl-centered">
  <div><img src="//placehold.it/120x120/69c/fff/" alt=""></div>
  <div><img src="//placehold.it/200x200/c69/fff/" alt=""></div>
  <div><img src="//placehold.it/160x160/9c6/fff/" alt=""></div>
  <div><img src="//placehold.it/240x240/fc6/fff/" alt=""></div>
  <div><img src="//placehold.it/160x160/9c6/fff/" alt=""></div>
  <div><img src="//placehold.it/200x200/c69/fff/" alt=""></div>

Another solution is to use flexbox with margin.

.owl-stage-outer {
  display: flex;
  flex-wrap: nowrap;
  flex-direction: column;
}
.owl-stage-outer > .owl-stage {
  margin:0 auto;
}

Answer 4

This works for me:

@media (max-width:500px) {
    .owl-carousel .owl-item {
        text-align:center;
    }
    .owl-carousel .item {
        float: none;
        display: inline-block;
    }
}

You might adjust it to your HTML though, but the idea is that you text-align a parent, and float:none and display:inline-block the child that holds the content, on mobile:

The solution with display table is OK, but for me the divs on the right and left side slides out from the container. My code is close the same, I changed the table and table-cell to block and inline-block

.owl-stage{
  display: block !important;
}

.owl-item{
  display: inline-block;
  float: none;
  vertical-align: middle;
}

.item{
  text-align: center;
}

The result (all images has different sizes):
