title: Difference between sw600dp and w600dp?
body: <p>Please elaborate on the difference between <code>sw&lt;N&gt;dp</code> and <code>w&lt;N&gt;dp</code>, in a simple way. I have studied the complete documentation of screen sizes but am confused between these two qualifiers <strong>sw&lt;></strong> and <strong>w&lt;></strong>.</p>
