Simple HH:mm:DD clock in HTML5 WITHOUT JavaScript

Question

is possible write counting clock only using HTML5? Or maybe only counter +1/each second.

Thanks a lot.

Answer 1

That would be frickin cool, but neither HTML5 nor CSS3 have the capacity to do this.

You need to use a real programming language (PHP/JS/Python...). Markup-Languages(like HTML or CSS) only work declarative.
