title: How to check that a class is displayed with Selenium Webdriver?
body: <pre><code>&lt;td class="base-detail-value"&gt;&lt;strong&gt;ORDER DATE: &lt;/strong&gt;&amp;nbsp;&amp;nbsp;19-May-2016 17:52:33
      &lt;span class="tooltip"&gt;
          &lt;div class="tt-content"&gt;
          May 19, 2016 10:52:33 AM PDT
          &lt;/div&gt;
      &lt;/span&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>I just want to check that td class='base-detail-tooltip' is displayed on the page I'm testing.</p>
  
  <p>I tried doing this, but I think I'm doing it wrong.</p>
  
  <pre><code>logo = driver.find_element(By.CSS_SELECTOR, 'base-detail-tooltip')
  logo.is_displayed()
  </code></pre>
