 <p>Bootstrap has no direct provision for partial columns.</p> <p>You can rewrite the stylesheet to operate on a different number of columns (i.e. 24).</p> <p>The <a href="http://getbootstrap.com/customize/" rel="nofollow">customize</a> page will let you specify a different number of columns and generate the stylesheet for you.</p> <p>Alternatively, you can check out Bootstrap from Git and modify <a href="https://github.com/twbs/bootstrap/blob/master/less/variables.less#L325" rel="nofollow">the variables file</a> to the same effect.</p>
