Position Div vertically down or up using CSS

Question

How to position the Div inside div vertically down or top.
Here What I have done so far.

 .lovecolbanner { margin-top: 10px; } 

 <div class="row_bottom"> <div class="lovecolbanner"> <span class="lovecolumnbanner">Love Column</span> </div> <div class="col-sm-3 col-xs-12"> <div class="pickup_item"> <a href="http://azlily.bex.jp/eccube_1/html/user_data/post06"> <div class="item_photo"><img src="{{ app.config.front_urlpath }}/img/column/09.jpg"></div> <dl> <dt class="item_name text-warning">恋愛やダイエットに関わる脳内物質</dt> <dd class="more_link text-warning">read more</dd> </dl> </a> </div> </div> <div class="col-sm-3 col-xs-12"> <div class="pickup_item"> <a href="http://azlily.bex.jp/eccube_1/html/user_data/post02"> <div class="item_photo"><img src="{{ app.config.front_urlpath }}/img/column/08.jpg"></div> <dl> <dt class="item_name text-warning">未婚じゃなくて、非婚です！</dt> <dd class="more_link text-warning">read more</dd> </dl> </a> </div> </div> <div class="col-sm-3 col-xs-12"> <div class="pickup_item"> <a href="http://azlily.bex.jp/eccube_1/html/user_data/post08"> <div class="item_photo"><img src="{{ app.config.front_urlpath }}/img/column/10.jpg"></div> <dl> <dt class="item_name text-warning">男性脳と女性脳（１）すれ違いが起きる原因</dt> <dd class="more_link text-warning">read more</dd> </dl> </a> </div> </div> </div> </div> </div> 

I will be keeping banners image in place of "love column" text
So for now that is just references.
Also When I do the padding top, Whole Div row_bottom moves down.

Update :
Changed span to div class and tried the following css, but It didnt give me what I wanted.

 .lovecolumnbanner { border: 4px solid pink; padding-top: 10px; padding-bottom: 14px; }
