  • 11. POSHPlain Old Semantic HTML
  • 12. POSH• Markup that has meaning• Markup that describes the content itself, not the presentation• Elements used for their intended purpose*• Valid*
  • 13. Not POSH <table> <tr> <td><a href="/">Home</a></td> <td><a href="/products/">Products</a></td> <td><a href="/services/">Services</a></td> <td><a href="/about/">About</a></td> </tr> </table>Also Not POSH <blockquote> <p>I need me some indented text!</p> </blockquote>
  • 14. POSH FTW <ul> <li><a href="/">Home</a></li> <li><a href="/products/">Products</a></li> <li><a href="/services/">Services</a></li> <li><a href="/about/">About</a></li> </ul>POSH & CSS <p>I need me some indented text!</p> p:first-child {text-indent: 25px;}
  • 15. POSH Tips• Use <h1>-<h6> for headings & to define content outline• Use <table> for tabular data, not layout• List elements (<ol>, <ul>, <dl>) for lists• Drop presentational elements (<u>, <big>, <center>) in favor of CSS• Semantic class and id naming
