Which bits of HTML5 can I use right now?
Rich: Lots of them! Here’s a short list of cross-browser (including IE) compatible techniques that you can use today:
- Change your doctype
- Simplify your character set
- Simplify your
<script>and<style>elements- Use block level linking
- Get into the habit of using HTML5 class names in your HTML4 markup
- Use the new form input types, as they degrade gracefully
- Use elements such as
<time>to add semantics that will be interpreted by leading browsers- Use the
<video>and<audio>elements, and then make them degrade gracefully (see our article on audio or Video for Everybody)For a clearer idea of what is or isn’t cross-browser compatible, check out these sites from Molly Holzschlag and Alex Deveria.
