title: Bootstrap Col width
body: <p>Please, first have a look on the attached image<a href="https://i.stack.imgur.com/8aouJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8aouJ.png" alt="enter image description here"></a></p>
  
  <p>I want <code>20%</code> in first column, but when I used <code>col-md-2</code>, it set <code>width: 16.6667%</code>
  how I set column <code>20%</code> using bootstrap. 
  Do I need to make my own CSS or there is a way to customise bootstraps3</p>
