To have a video inserted in the page with the Html 5 video player I guess the page format itself has to be set to Html5 and cannot stay to Html 4.01 Transitional right ?
If changing the page format to Html 5 would it make sense to directly change the whole website instead of only one single page ?
Knowing that our various websites have been developed under WWB 7, 8, 10, and now 12, always using the Html 4.01 Transitional for all pages is it safe and without concern to move to Html 5 today ?
Please help.
Thanks!
I didn't find the right solution from the Internet.
