title: Is using .container mandatory with bootstrap 3?
body: <p>I am working on a Bootstrap 3 project and I am trying to understand of the use of the .container class is mandatory. I am trying to achieve a full-width page and if I use the .container it sort of creates margins on the left and right sides.</p>
  
  <p>So I tried coding my page without wrapping my contents inside .container. The result is the following:</p>

  <p>But, when I wrap it all inside the .container it magically fixed itself, have a look:</p>

  <p>Any idea how I can achieve a full width age with bootstrap 3?</p>
