title: Find element by class name
body: <p>I'm trying to find one tag using <code>we.find_element_by_css_selector('p.p1.transfer strong.ng-binding').text</code></p>
  
  <p>The problem is that there is sometimes a 'strong' tag before the tag I'm searching for which is very similar but it's class is: <code>class="ng-binding ng-hide"</code> instead of <code>class="ng-binding"</code>. But when I try to find it it finds the first tag.</p>
  
  <p>I've tried also <code>.find_element_by_css_selector('p.p1.transfer').find_element_by_class_name('ng-binding').text</code> which did not work too, it found the tag which class is named <code>ng-binding ng-hide</code></p>
  
  <p>Have you any advice how to find the tag?</p>
