title: django-crispy-forms - Default classes
body: <p>I'm trying to use the Bootstrap package with <a href="https://github.com/maraujop/django-crispy-forms" rel="nofollow">django-crispy-forms</a> on an existing project.</p>
  
  <p>I have ~15 forms in which I'd like to have these classes:</p>
  
  <pre class="lang-py prettyprint-override"><code>label_class = 'col-sm-3'
  input_class = 'col-sm-9'
  </code></pre>
  
  <p><strong>Is there a way to specify these defaults</strong> on settings or somewhere else without having to update all my forms ?</p>
  
  <hr>
  
  <p>Also, I was previously using <a href="https://github.com/tzangms/django-bootstrap-form" rel="nofollow">django-bootstrap-form</a> where I was specifying the classes from the templates:</p>
  
  <pre><code>{{ my_form|bootstrap_horizontal:'col-sm-3' }}
  </code></pre>
  
  <p><em>I find more logical to control the rendering from the template rather than from the form definition. A form can be used in several pages without having the same rendering</em></p>
