twitter boostrap (responsive) : .span3 taking .span6 full width behaviour when width between 320px and 797px
问题 With twitter bootstrap.css and bootstrap-responsive.css, .span* become equivalent to a .span12 under 768px . This behaviour is perfectly fine when text is embedded, but for pictures it make sense to use a 2x2 layout between 4x1 and 1x4 . How to obtain this 2x2 layout from 767px to 320px ? 768px wide (4x1) 767px wide (1x4) HTML: <div class="row-fluid"> <ul class="thumbnails"> <li class="span3"> <div class="thumbnail" href="#"> <img alt="" src="http://placehold.it/200x150"> <p>1</p> </div> </li
