title: Scrapy: Unable to access class despite of it's there
body: <p>I am trying to scrape <a href="http://www.rebeccaminkoff.com/stacey-sneaker-r17-light-blue" rel="nofollow noreferrer">this</a> page, I am trying to fetch Color Name, <em>LT. BLUE</em>. From Chrome I see HTML:</p>
  
  <pre><code>&lt;div id="desc-options"&gt;&lt;div class="option"&gt;&lt;span class="label"&gt;Color:&lt;/span&gt; LT. BLUE&lt;/div&gt;&lt;div class="option"&gt;&lt;span class="label"&gt;Size:&lt;/span&gt; 6.5&lt;/div&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I tried <code>response.css("#desc-options")</code> to access everything inside but returns <code>[]</code>. Even <code>BeautifulSoup</code> is failing.</p>
