Responsive Grid of Squares in Bootstrap

Question

I want to create a grid of responsive images that are always squared in Bootstrap.

So far I got this: Jsfiddle Link

This part forces the elements to be squared all the time:

.frontpage_square {
    position:relative;
    overflow:hidden;
    padding-bottom:100%;
}

.frontpage_square img {
    position:absolute;
}

The bigger square on the left and the nine smaller ones on the right are correct, but I can't figure out how I can spread the nine squares on the right over the full height. So basically they should take the whole height of the left, bigger square.

Answer 1

It is simple, you aren't arranging your divs properly. Make use of bootstrap by using the divs properly. Once that is done, you can make the column all same size by using this S.O. question.

<div class="row">
    <div class="col-sm-6 panel">

            <a href="#" class="thumbnail">
                <div class="frontpage_square">
                    <img src="" class="img img-responsive full-width" />
                </div>
