title: Why Selenium not recognised class with space in the name using CSS?
body: <p>I want to fine this <code>WebElement</code>:</p>
  
  <pre><code>&lt;div class="title_bar bar ng-sss" ng-rr="!isBulkMode"&gt;
  </code></pre>
  
  <p>So when using <code>CSS</code>:</p>
  
  <pre><code>div[class=title_bar bar ng-sss]
  </code></pre>
  
  <p>This element could not found.</p>
  
  <p>And with <code>Xpath</code> this works:</p>
  
  <pre><code>//div[@class='title_bar bar ng-sss']
  </code></pre>
