title: Zurb Foundation full body background
body: <p>I want to apply background to whole page. When I add code to CSS, nothing happens, but when I write some text in HTML, only part behind text is painted to color that I previously set in CSS.</p>
  
  <p>I'm using Sass and when I exclude app.css, everything gets normal (because Foundation is excluded).</p>
  
  <p>Here is my CSS</p>
  
  <pre><code>/* line 5, ../sass/master.scss */
  body {
    background: url("../img/bg.png");
  }
  
  /* line 8, ../sass/master.scss */
  header {
  background: black;
  }
  </code></pre>
  
  <p>Anybody knows solution?</p>
