Align two divs horizontally side by side center to the page using bootstrap css

This should do the trick:

<div class="container">
    <div class="row">
        <div class="col-xs-6">
            ONE
        </div>
        <div class="col-xs-6">
            TWO
        </div>
    </div>
</div>

Have a read of the grid system section of the Bootstrap docs to familiarise yourself with how Bootstrap’s grids work:
