show static ad space only for large screen in materialize css

Question

part one is responsive but ad space is not responsive here. then how to show this ad-space?

<div class="row">
 <div class="col s12 m12 l10">
    <!--part one-->
 </div>
 <div class="hide-on-med-and-down showAdPart">
    <!-- 300x600 ad space--> 
 </div>
</div>

Answer 1

use l12 class for 100% or your width and follow like,

 <div class="col s12 m12 l12 partOne">
    <!--part one-->
 </div>
 <div class="hide-on-med-and-down showAdPart">
    <!-- 300x600 ad space--> 
 </div>

css : use calc()

@media screen and (min-width: 993px){   /* large screen */
  .partOne.col.l12{
      width: -webkit-calc(100% - 300px);
      width:    -moz-calc(100% - 300px);
      width:         calc(100% - 300px);
 }
}
