Is it possible to achieve dynamic column adjustment in Bootstrap 2 like the example shown here? I want the layout to display 4 columns when the window is wide enough, but switch to 2 columns when the width of the window decreases. Since Bootstrap 2 only uses span classes such as span4 and span2, how can I implement this without converting to Bootstrap 3?
Below is a snippet of the HTML code:
<div class="col-lg-3 col-md-4 col-xs-6 thumb">
<a class="thumbnail" href="#"><img class="img-responsive" src="http://placehold.it/400x300"></a>
</div>
<div class="col-lg-3 col-md-4 col-xs-6 thumb">
<a class="thumbnail" href="#"><img class="img-responsive" src="http://placehold.it/400x300"></a>
</div>
<div class="col-lg-3 col-md-4 col-xs-6 thumb">
<a class="thumbnail" href="#"><img class="img-responsive" src="http://placehold.it/400x300"></a>
</div>
<div class="col-lg-3 col-md-4 col-xs-6 thumb">
<a class="thumbnail" href="#"><img class="img-responsive" src="http://placehold.it/400x300"></a>
</div>
<div class="col-lg-3 col-md-4 col-xs-6 thumb">
<a class="thumbnail" href="#"><img class="img-responsive" src="http://placehold.it/400x300"></a>
</div>
<div class="col-lg-3 col-md-4 col-xs-6 thumb">
<a class="thumbnail" href="#"><img class="img-responsive" src="http://placehold.it/400x300"></a>
</div>
