Let's HTML5-ify Drupal!

HTML5 is hot. It will change the web. Drupal could get left behind if we don't get HTML5 support into core.

Specifically, core needs support for HTML5 Form API so that contrib project maintainers can leverage the power of HTML5 forms.

The markup for menus, scripts, styles, and published date is just too hard to change for people who aren't Drupal theming experts. They will get frustrated trying to make Drupal output HTML5.

This is a good time to work on the default theme markup for Drupal core — the node, page, block, comment tpls, etc., as well as for Bartik.

Core leads the community. Let's lead everyone into the future.

Why is HTML5 cool?

• HTML4 is from 1999. HTML5 supports the websites people are creating now.
• Powerful APIs for developing applications.
• Lots of tools for making mobile apps/sites.
• Better UX for entering content via forms, especially for mobile devices.
• Using HTML5 instead of jQuery for certain interfaces would lighten core, make sites run faster, and allow for easier customization.
• Semantic HTML means better findability and accessibility long-term.
