title: Python Splinter clicking button CSS
body: <p>I'm having trouble selecting a button in my Splinter script using the <code>find_by_css</code> method. The documentation is sparse at best, and I haven't found a lot of good articles out there with examples.</p>
  
  <pre><code>br.find_by_css('div#edit-field-download-files-und-0 a.button.launcher').first.click()
  </code></pre>
  
  <p>...where <code>br</code> is my browser instance.</p>
  
  <p>I've tried a few different ways of writing it.  I'm really not sure how I'm supposed to do it because the documentation doesn't give any hard examples of the syntax.</p>
  
  <p>Here's a screenshot of the element.</p>
  
  <p><img src="https://i.stack.imgur.com/t6Nni.png" alt="Here&#39;s a screenshot of the element I&#39;m trying to manipulate"></p>
  
  <p>Sorry the screenshot kind of sucks.</p>
  
  <p>Does anyone have any experience with this?</p>
