title: multiple media queries declaration on responsive design
body: <pre><code>@media only screen and (min-device-width: 480px) {
      #something{display:none !important;
  }
  </code></pre>
  
  <p>I use this as my mobile css set, but it effect my elements still in larger screen size (more than 480px), do I have to declare another set of media queries on larger size. </p>
