title: Zero border not working in html
body: <p>I am doing an example having tables in a table, but parent table should not have border. I tried, but it is working. I check in W3School css tutorial also even no result. I tried:</p>
  
  <ol>
  <li><code>style="border: none;"</code></li>
  <li><code>border:0</code> </li>
  </ol>
  
  <p>Both not working in Chrome</p>
  
  <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>th {
    border: 1px solid black;
    padding-left: 7px;
    padding-right: 7px;

  td {
    border: 1px solid black;
    padding-left: 7px;
    padding-right: 7px;
