title: How can I change cols of textarea in twitter-bootstrap?
body: <p>If I change the value of :rows, it works. But it stays at the default cols whatever value I set with ':cols =>'. Column width won't change.</p>
  
  <p>I viewed the html source and it reflected the change. I wonder that bootstrap's CSS might be the suspect...</p>
  
  <p>HTML (there is a "cols=" in the final HTML, but column width stays at the default value, which is 30. I can't believe my eyes!)</p>
  
  <pre><code>&lt;textarea cols="100" id="comment_body" name="comment[body]" rows="5"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>Rails:</p>
  
  <pre><code>&lt;%= form_for([@post, @post.comments.build]) do |f| %&gt;
    &lt;div class="field"&gt;
      &lt;i class="icon-user"&gt;&lt;/i&gt;
      &lt;%= f.text_field :commenter %&gt;
    &lt;/div&gt;
    &lt;div class="field"&gt;
      &lt;i class="icon-comment"&gt;&lt;/i&gt;
      &lt;%= f.text_area :body, :rows =&gt; 5, :cols =&gt; 100 %&gt;
    &lt;/div&gt;
    &lt;div class="actions"&gt;
      &lt;%= f.submit %&gt;
    &lt;div&gt; 
  &lt;% end %&gt;
  </code></pre>
