With all the buzz around HTML5, everyone is eager to make the leap towards web 3.0. HTML5 enforces semantic structure of web pages with new tags like <header> and <footer>, but using these right away is not a good idea due to browser issues and support. But you can implement some facilities right now in your current web projects.
- Use this doctype: <!DOCTYPE html>
- No need for “type” attribute to include links and scripts. e.g. <link rel =”stylesheet” href =”style.css”/>
- Use this meta for charset: <meta charset=”UTF-8″>
If you are using popular CMSs like WP and Drupal, many plugins out there will help you in implementing semantic technology in your web site. Drupal 7 will ship with RDFa as a core component. You can also use microformats to inject meta data into your existing projects and make information like product reviews, places, and contact information semantically rich.
