title: background of every page except homepage are blured
body: <p>I'm trying to make a website using wordpress, and I got a default background for every page.</p>
  
  <p>The homepage background shouldn't be blur and all the rest of the pages should be, the problem is that I blur all the pages and cannot blur specific pages.</p>
  
  <p>this is the code:</p>
  
  <pre><code>.container-centered
  {
    position: fixed;
    left:0;
    top:0;
    height:100%;
    width:100%;
    background-image: url("http://localhost/wordpress/wp-content/uploads/fundo-home-1920px.jpg");
    background-repeat: no-repeat;
    background-size: cover;
    background-position: center;
    -webkit-filter: blur(13px);
    -moz-filter: blur(13px);
    -o-filter: blur(13px);
    -ms-filter: blur(13px);
    filter: blur(13px);
  }
  </code></pre>
