Bootstrap: add margin/padding space between columns

Simply add a div within col-md-6 that has the extra padding that you need. The col-md-6 is the ‘backbone’ to keep the column integrity, but you can add additional padding within it.

<div class="row">
    <div class="text-center col-md-6">
        <div class="classWithPad">Widget 1</div>
    </div>
    <div class="text-center col-md-6">
        <div class="classWithPad">Widget 2</div>
    </div>
</div>

CSS

.classWithPad { margin:10px; padding:10px; }
