I'm trying to get the content in <div class="col-md-2 col-lg-2"> in the middle to align to middle, but to no avail. 
I know that setting the columns to a size of 2 will not fill the space of the grid system of 12 columns, but I want it to be aligned to the middle regardless. 
<div class="row">
    <div class="col-lg-12">
        <h1 class="content-header">Header</h1>
        <div class="row">
           <div class="col-md-2 col-lg-2">
               content
           </div>
           <div class="col-md-2 col-lg-2">
             content
           </div>
        </div>
    </div>
