title: SASS: Deleted styles from SASS still showing in generated CSS?
body: <p>Can you delete markups from a generated css file using sass?</p>
  
  <p><strong>For example, I have this on my scss file:</strong></p>
  
  <pre><code>body{ background:$dark; }
  </code></pre>
  
  <p><strong>My generated CSS file will look like this:</strong></p>
  
  <pre><code>body{ background: #000; }
  </code></pre>
  
  <p>So what will happen if I delete that line of code in sass? (not commented but completely deleted)</p>
  
  <p>So far, what happens with my project is that after I compile, the generated css file retains the markup that I've made earlier. 
  So my CSS file still have this line even if I deleted it on my scss file:</p>
  
  <pre><code>body{ background: #000; }
  </code></pre>
  
  <p>Is this normal? or is it an error in my compiler? 
  Can sass only create,edit or overwrite an existing markup in CSS and it cannot delete it? In other words, once the markups are generated in CSS, you can only modify them and you have to manually remove the line of codes in css if you decide to delete it? </p>
