title: Chrome developer tools, what is capture full size screenshot?
body: <p>I realize that there is this <code>Capture full size screenshot</code> on chrome developer mode. After trying out the features i've notice that there will a slight change of UI design after taking the screenshot (the screenshot seem wider than the viewport i saw).</p>
  
  <p>I have screenshot the screen with iphone 6/7/8 device. </p>
  
  <p>May I know <strong>what is the difference of 'Capture full size screenshot' and 'Capture screenshot'</strong> and why are the screenshots are different?</p>
