This prevents conflict when using col-md-* and col-lg-* classes together on the same element.
Example:
<div class="col-lg-2 col-md-3 col-md-pull-4">
...
</div>
This causes the col-md-pull-4
class to pull the element even when the browser window is larger than @screen-lg-min
. This problem is fixed with this pull request.
