@VITSUSAFeb 20.2020 — #HTML4 uses common structures like header, footer but html 5 uses new struc- tures such as drag, drop and much more. HTML 4 cannot embed video or audio directly and makes use of flas plash player for it. and cannot handle in- accurate syntax but html5 can contain embeded video and audio without using flas player and it is capable of handling inaccurate syntax.
