title: Is it bad practice to comment out single lines of CSS with //?
body: <p>I have recently started using <code>//</code> to "comment" out single lines of CSS code. I understand that I am not actually commenting out the line; I am just breaking it (I should use <code>/* ... */</code>), but it has the same effect. The line is then terminated by the <code>;</code> and the following code works fine.</p>
  
  <p>I could delete it, but often I prefer not to in case I want to put it back in later or see what I had been using if I come back to it.</p>
  
  <p>Example:</p>
  
  <pre><code>li{
      float:left;
      //list-style-type:none;
      text-indent:0px;
  }
  </code></pre>
  
  <p>Can I get away with this, or is it likely to cause me problems?</p>
