title: Placeholder text is not showing when using rails and bootstrap
body: <p>I am not sure why I can't see my <strong>placeholder</strong>.  </p>
  
  <p>I am using Rails and Bootstrap to generate the code:</p>
  
  <pre><code>= form_tag activity_path(@activity), method: :get do
    = text_field_tag :start_time," ", {placeholder: 'Start Date', class: 'pull-left input-small'}
    = text_field_tag :end_time," ", {placeholder: 'End Date', class: 'pull-left input-small'}
    %span.btn= submit_tag 'Show custom dates', class: 'btn'
  </code></pre>
  
  <p>Here is the generated code: </p>
  
  <pre><code>&lt;input class="pull-left input-small" id="start_time" name="start_time" placeholder="Start Date" type="text" value=" " /&gt;
  
  &lt;input class="pull-left input-small" id="end_time" name="end_time" placeholder="End Date" type="text" value=" " /&gt;
  </code></pre>
  
  <p>The problem is that I can't see the placeholder. I tried setting it to a different color <code>input[placeholder] { color: ...}</code> but that didn't seem to work either. Any idea why this is happening? Thank you.</p>
  
  <p><strong>[EDIT]</strong> </p>
  
  <p>I added <code>@placeholderText: #080808;</code> in my <strong>bootstrap_and_overrides.css</strong> file but that didn't seem to do the trick either. </p>
