title: What replaces cellpadding, cellspacing, valign, and align in HTML5 tables?
body: <p>In <strong>Visual Studio</strong>, I'm seeing these warnings:</p>
  
  <blockquote>
    <ul>
    <li>Validation (HTML 5): Attribute 'cellpadding' is not a valid attribute of element 'table'.</li>
    <li>Validation (HTML 5): Attribute 'cellspacing' is not a valid attribute of element 'table'.</li>
    <li>Validation (HTML 5): Attribute 'valign' is not a valid attribute of element 'td'.</li>
    <li>Validation (HTML 5): Attribute 'align' is not a valid attribute of element 'td'.</li>
    </ul>

  <p>If they are not valid attributes in <strong>HTML5</strong>, what replaces them in CSS?</p>
