Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

  <h1>Table Rows with Different Display Properties</h1>
  <p>
    For this example, individual rows are set to whatever <code>display</code> property you choose, which breaks the entire table structure. To demonstrate, the buttons below converts all but the header rows to whichever style you press.
  </p>
  <p>
    Note that only the first row (of data, not the header row) has ARIA properties set. These properties will retain semantics for all but <code>display: contents</code>, but can do nothing for the layout.
  </p>
  <p>
    <button onclick="ToggleRowDisplay('block',this);">Convert rows to <code>block</code>.</button>
    <button onclick="ToggleRowDisplay('inline',this);">Convert rows to <code>inline</code>.</button>
    <button onclick="ToggleRowDisplay('contents',this);">Convert rows to <code>contents</code>.</button>
    <button onclick="ToggleRowDisplay('table-row',this);">Reset rows to <code>table-row</code>.</button>
