Bootstrap Thumbnails Leave gaps in between - css

Question

I'm trying to make a grid of Boostrap unevenly sized thumbnails. But some thumbnails are uneven, resulting in huge gaps between some rows.
I don't have any styling on the thumbnails.
Is there a way to fix it without adding something like Masonry/Isotope/Salvattore?

You can use two <div> or two .row tags like this:
<div class="row">
<div class="col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<p>Thumbnail caption</p>
</div>
</div>
</div>
<div class="col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<p>Thumbnail caption</p>
</div>
</div>
</div>
<div class="col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<p>Thumbnail caption</p>
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<p>Thumbnail caption</p>
</div>
</div>
</div>
<div class="col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<p>Thumbnail caption</p>
</div>
</div>
</div>
<div class="col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<p>Thumbnail caption</p>
</div>
</div>
</div>
</div>

The cleanest way to fix your layout is to use a masonry type of layout. It will allow for the smoothest look and be a very fluid and responsive layout when dealing with mixed sized media. Though if you are in complete control of the data/images being placed on the site I would suggest creating each image to be identical in size and type. If you would like I can provide an example I have created using a masonry type of layout with thumbnails and Bootstrap.
Edit to add example code:
/* CSS styles */
.row {
-moz-column-width: 12em;
-webkit-column-width: 12em;
-moz-column-gap: 1em;
-webkit-column-gap:1em;
column-width: 12em;
column-gap: 1em;
column-fill: balance;
width: 100%;
}
/* Outer div block */
.section-block {
display: block;
padding: .25rem;
width: 100%;
}
/* Inner div block */
.section-item {
position:relative;
display: inline-block;
width: 100%;
}
.section-item img{
width: 100%;
}
//Wrapper for each img you are adding
<div class='section-block'>
<div class='section-item'>
<div>
<a href='#' class='thumbnail' data-toggle='modal' data-target='#id'>
<img src='/imgs/image.jpg'>
<p class='caption'>Image Caption</p>
</a>
</div>
</div>
</div>
I used this in conjunction with php to get all my images from a db then I looped over each image and echo'd to the page with the above syntax. This should work without having to use any additional js libraries beyond what you are using for bootstrap. This gives you a very responsive masonry style of layout that works in modern browsers.
