如何使用 bootstrap 3 使带有背景图像的 div 响应?
引导程序 3 中的 img-responsive 类是否可能?
我的 div 是空的,如下所示:
<div class="row">
<div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
<div class="workflowstep workflowstep1 img-responsive">
</div>
<div class="workflowstep workflowstep2 img-responsive">
</div>
<div class="workflowstep workflowstep3 img-responsive">
</div>
<div class="workflowstep workflowstep4 img-responsive">
</div>
<div class="workflowstep workflowstep5 img-responsive">
</div>
<div class="workflowstep workflowstep6 img-responsive">
</div>
</div>
</div>
