title: CSS background image duplicates itself
body: <p>I would like to know why this CSS code shows two of the same backgound image, even when I am only setting one, below is the code:</p>
  
  <pre><code>html, body {
  margin: 0;
  padding: 0;
  }
  
  body {
  font-family: 'Roboto', sans-serif;
  font-weight: 100;
  }
  
  .container {
  margin: 0 auto;
  max-width: 940px; 
  padding: 0 10px; 
  }
  
  
  /* Header */
  .header {
    height: 800px;
    text-align: center;
    background-repeat: no-repeat;
    background: url(http://www.bolsamania.com/cine/wp-    content/uploads/2016/07/9-2.jpg);
    color: white;
    padding: 100px;
    background-repeat: no-repeat;
  }
  
  .header .container {
      position: relative;
  top: 200px;
  }
  
  .header h1 {
  font-size: 80px;
  line-height: 100px; 
  margin-top: 0;
  margin-bottom: 80px;
  }
  
  @media (min-width:850px) {
  .header h1 {
      font-size: 120px;
  }
  }
  
  .header p {
  font-weight: 500;
  letter-spacing: 8px;
  margin-bottom: 40px;
  margin-top: 0;
  }
  
  .btn:hover {
  background: #117bff;
  cursor: pointer; 
  transition: background .5s;  
  }
  
  
  /* Nav */
  .nav ul {
  list-style: none;
  margin: 0 auto; 
  padding: 30px 0;
  text-align: center;
  
  }
  .nav ul li {
    display: inline-block;
    background-color: white;
    padding: 1px 2px 1px 2px;
    border: 1px solid black;
    border-radius: 5px;
  
  }
  
  .nav {
    background-color: black;
  }
  
  /* Main */
  .main .container {
  margin: 80px auto;
  }
  
  
  /* Jumbotron */
  .jumbotron {
  height: 600px; 
  text-align: right;
  }
  
  .jumbotron .container {
  position: relative;
  top: 220px;
  }
  
  
  /* Footer */
  .footer { 
  font-size: 14px;
  }
  
  /* Media Queries */
  @media (max-width: 500px) {
    .header h1 {
  font-size: 50px;
  line-height: 64px;
  
    }
  
    .main, .jumbotron {
  padding: 0 30px;
  
    }
  
    .main img {
      width: 100%;
    }
  }
  
  .btn {
    border: 1px solid black;
    text-decoration: none;
    border-radius: 5px;
    padding: 5px;
    background-color: #808080;
    color: white;
    margin-bottom: 10px;
  }
  
  .main img {
    float: left;

  <p>The image will repeat even when I added the:<code>background-repeat: no-repeat;</code>
  Thanks in advance for the help.</p>
