Bootstrap 3 responsive with multiple break points

Question

I'm using latest Bootstrap 3.0 RC1 and trying to build an image overview with responsiveness and multiple break points when the images becomes too small (like seen on Dribbble).

Issues:

1. The image scaling only appears when there's two or less on an line (it should work with 3-4 images as well)
2. My break lines OR the responsiveness cause different image sizes. I need to make sure that the max img size after breaks is the same as max size when there's 4 on a row. Example when breaking into two or one the images will initially appear much larger than the largest size with 4 in a row.

I hope someone can help me out, I'm a beginner to building responsive stuff..

Best regards

It doesn't appear that you are using Bootstrap 3 RC1. The link in your fiddle is broken. Bootstrap RC1 doesn't have .row-fluid anymore.

You could just simplify everything by letting the responsive features in 3 do the work for you. BS3 now has 3 grid sizes -- tiny, small and large that are used to manipulate display on different devices / widths. You could do something like this..

<div class="row">
    <div class="col-lg-3 col-sm-4 col-6">
        <a href="#" class="thumbnail">
             <img src="http://placehold.it/350x150" class="img-responsive">
        </a>
    </div>
    <div class="col-lg-3 col-sm-4 col-6">
        <a href="#" class="thumbnail">
             <img src="http://placehold.it/350x150" class="img-responsive">
        </a>
    </div>

     ...
</div>

That will get you..

• 4 per row on large screens (col-lg-3)
• 3 per row on tablets (col-sm-4)
• 2 per row on "tiny" phones (col-6)
