title: <button> is not inheriting css properties properly
body: <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>h2 {
    text-align: center;
    font-family: fantasy
  }
  .form {
    margin-top: 100px;
  }
  .form * {
    margin: auto;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;form method="post"&gt;
    &lt;div class="form"&gt;
      &lt;table&gt;
        &lt;tr&gt;
          &lt;td class="label"&gt;Username&lt;/td&gt;
          &lt;td&gt;
            &lt;input type="text" name="username" value={{username}}&gt;
          &lt;/td&gt;
        &lt;/tr&gt;
  
        &lt;tr&gt;
          &lt;td class="label"&gt;Email (optional)&lt;/td&gt;
          &lt;td&gt;
            &lt;input type="text" name="email" value={{email}}&gt;
          &lt;/td&gt;
        &lt;/tr&gt;
  
        &lt;tr&gt;
          &lt;button type="submit"&gt;Create Account!&lt;/button&gt;
        &lt;/tr&gt;
      &lt;/table&gt;
  
    &lt;/div&gt;
  &lt;/form&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>When I run it in Chrome, the button element seems to completely disregard the css and appear at the left end of the screen, that too <em>above</em> the rest of the table rows (when it should in fact be below!).</p>
  
  <p>I tried to replace it with an <code>&lt;input type="submit"&gt;</code> tag, but it shows the same problem.</p>
  
  <p>Any ideas why this button element is misbehaving?</p>
