body: <p>I am Using Media Query In My Web Application For Width And Margins</p>
  
  <pre><code>    @media (max-width:1050px) {
      .row-fluid .span3 {
          width: 42%;
  
      }
  
      .row-fluid .span3 
      {
          width: 50%;
      }
  }
  
  @media(max-width:1050px) {
      .span3 {
          width: 220%;
      }
  
      .span3 {
          width: 220%;
      }
  }
  @media(max-width: 1050px)
      {
       .row-fluid   .span3 {
  
                 margin-left:35%;
              }
  
     .row-fluid .span3 {
                  margin-left:35%;
              }
          }
  
          @media(max-width: 1050px)
      {
          .span3 {
  
                  width: 320%;
              }
  
      .span3 {
                  width: 320%;
              }
          }
  </code></pre>
  
  <p>It Is Working Fine With Width But Margin-Left Is Not Working And Guys I Don't Have Much Idea About Media Query That's Why My Code May Not Be Much Accurate.</p>
