Why is transitional and not strict validation for xhtml

Recommended list of Doctype declarations. I guess I meant the doctype mainly. That is great news!! Thank you! I doubt very much we will have to do that. Pointing 3 of my browsers to that url gave the following scores measuring how well they support HTML5. In that case I would explain to the client that not all their required to be supported browsers support HTML5 features and so give them the opportunity to water down their site specifications if they wish.

Yes it will probably mean a little more work for developers, but I prefer to think of it as an opportunity to make a few extra dollars.

Since HTML5 is still only a draft there is still plenty of time for it to change before it becomes a standard. Also judging by the huge percentage of web sites that are yet to finish upgrading to use HTML4 13 years after it became a standard it will probably be several decades before HTML5 starts to become important. I have no errors with xhtml transitional. Is there an advantage to passing xhtml strict? Transitional doctypes are there to help old sites ease through the transition to modern standards.

They are totally inappropriate for new sites. Defiantly convert to a strict doctype and address the out-of-date code you are using. If you have any trouble with sorting out the validation issues, please feel free to post back. The full markup is required for a definitive answer.

But I never was able to find a complete list of tags listed by parent and chld. Do you know where such a list can be found? Notify me of follow-up comments by email. Notify me of new posts by email.
