How to get grid items to align center in Bootstrap views?
If you can create div tag, you can use css as show below. 

Example:

html: &lt;div class="secLayerContainer"&gt;&lt;div class="secLayerContent"&gt;.....&lt;/div&gt;&lt;/div&gt;

css: 
.secLayerContainer { display: inline; float: left; width: 100% }
.secLayerContent { display: block; float: none; width: 200px; margin: 0px auto}  

note: 200px also can change 20%. (your preference)
