title: What is the difference between padding-left and padding-start?
body: <p>While inspecting some code I found this new declaration: <code>-webkit-padding-start</code> but I am been unable to understand what is the difference with the existing <code>padding-left</code> property.
  I have already read the page on <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/-moz-padding-start">Mozilla Developers</a> and created a <a href="http://jsfiddle.net/avrMw/1/">fiddle</a>, but I am still unsure.</p>
