title: Bootstrap classes for laravel 5 form submit button
body: <p>Below is the part of input field and submit button.<a href="https://i.stack.imgur.com/nt1fX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nt1fX.png" alt="enter image description here"></a></p>
  
  <p>I want to increase the width of submit button as the input field using bootstrap. </p>
  
  <p>Here is my code.</p>
  
  <pre><code> &lt;div class="form-group col-md-6"&gt;
   {!! Form::label('Event Photo') !!}
   &lt;/div&gt;
   &lt;div class="form-group col-md-6"&gt;
   &lt;input type='file' name='photo' id ='photo' class ='form-control'/&gt;
   &lt;/div&gt;
  &lt;div class="form-group col-md-12"&gt;
      {!! Form::submit('Add', array('class'=&gt;'btn btn-primary')) !!}
  &lt;/div&gt;
  </code></pre>
  
  <p>But the button size can't get increased like that. Where am I wrong? How should I solve that?</p>
