SoloLearn says that marquee not support in html 5 but marquee is supported in html5
Error is SoloLearn answer
the "support" differs from the word "doesn't work".It is not supported mean browsers written in each html5 don't readily accept it.its deprecated
I understand that marquee has been depricated but as adarsh says a lot of browsers still support this.
not directly supported by the "html5 standard". but the browsers ( at least some of them) might still understand/support the marquee tag.
Actually <marquee> still works in most of browsers, even in an html5 document... The trick is that <marquee> had never been part of html specification, and html5 specification discourage it use and implementation, meaning that it should becomes unsupported by mostly browsers in future ^^
