title: difference between '-webkit-box-shadow' & 'box-shadow' in css
body: <p>Recently I have started to learn css here I came to know about </p>
  
  <pre><code>box-shadow 
  </code></pre>
  
  <p>property in CSS then I came to know another property </p>
  
  <pre><code>-webkit-box-shadow:
  </code></pre>
  
  <p>and also</p>
  
  <pre><code>-moz-box-shadow:
  </code></pre>
  
  <p>which also used to give shadow to the shadow. I just can't differentiate between them. Can anybody help me to understand exactly this properties?</p>
  
  <p>Thanks in advance to helpers.</p>
