title: Selenium - Difference between WebDriver.findElement() and WebElement.findElement()
body: <p>I was using <code>WebElement.findElement(By.cssSelector('')).click();</code> to find an element on a page , but it returned <code>"Unable to locate element"</code>,  But when I used <code>WebDriver.findElement(By.cssSelector('')).click();</code> then it was able to find the element and clicked on it.</p>
  
  <p>I am unable to understand the difference between the <code>findElement()</code> of the two interfaces.
  Kindly Help.  </p>
