title: Letter spacing and line-height not only affecting text elements
body: <p>I defined main stylesheet (default CSS of my project) like this:</p>
  
  <pre><code>body {
      color: #000000;
      text-align: center;
      margin: 0px;
      padding: 0px;
      font-size: 0.75em; /* 12px */
      line-height: 1.5; /* font-size:1(12px) + line-space:0.33(4px) = 16px */
      letter-spacing: 0.03em;
  }
  </code></pre>
  
  <p><code>letter-spacing</code> and <code>line-height</code> works perfectly.
  but, I found that two of them affect ul-li elements too.
  I want that they affect text only not ul-li or any other elements.</p>
  
  <p>Is there any side-effect on letter-spacing and line-height which I don't know?
  If so, how could I make line-height and letter-spacing affect text only?</p>
