title: How to solve find_element_by_class_name() throwing "Unable to find element with class name '...'"?
body: <p>The webpage (see <code>driver.get()</code> below) seems to have one table with class name as table. I can't seem to locate it using the code below. </p>
  
  <p>I was under the impression that I could locate these type of Javascript elements using Selenium. </p>
  
  <pre><code>import time
  
  from selenium import webdriver
  from selenium.webdriver.common.keys import Keys
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  driver.quit()
  driver = webdriver.PhantomJS()
  
  driver.get('http://investsnips.com/list-of-publicly-traded-micro-cap-diversified-biotechnology-and-pharmaceutical-companies/')
  
  
  content = driver.find_element_by_css_selector('table.table')
  x = driver.find_element_by_class_name("table")
  </code></pre>
  
  <p>I'm getting this error (content nor x work)</p>
