@amoun having so many lines of code makes HTML5 validation a pain, so it must be an on-going task.

I'm preparing a patch with the main changes that you need to apply to fix your current issues. I'll be back to you as soon it's ready.

Please, keep posting anything you find and we will try to put fixes into the standard releases.

Thanks.

@amoun basically we are definitely willing to include validation fixes. It's just that we have 3500 todos on the list already and it's hard to make them all priority #1 ;)

Any chance you could fork b2evolution on GitHub and check in your fixes into your forked branch? This would allow us to easily merge them into the next release. PLUS we could continue to follow your branch over time for additional fixes.

@amoun I had already done some fixes and you can find them here: https://github.com/mgsolipa/b2evolution/commits/feature/html5-validations. Later today I will push the calendar widget related fixes to the same branch and them send a Pull request to the main b2evolution repository.

As you can see, I followed the same technique mentioned by @fplanque, maybe you can do the same for further validations if you want to.

Regards!
