Ces tus W3C tshaj tawm tias nws yuav tsis tau tsim tshiab versions of HTML, thiab yuav pib ua kom pom tseeb ntawm cov huab cua extensible HTML los yog XHTML. Lawv pom zoo kom cov Web designers siv HTML 4.01 rau lawv cov ntaub ntawv HTML.
Nyob ib ncig ntawm no point, kev loj hlob split tawm. Lub W3C tau teem rau XHTML 1.0, thiab tej yam zoo li XHTML Basic pib cov kev pom zoo hauv 2000 thiab onwards. Tiam sis Web designers tsis xav txav mus rau lub qauv ntawm XHTML, yog li xyoo 2004, lub Web Hypertext Application Technology Group (WHATWG) pib ua hauj lwm rau ib qho tshiab version HTML uas tsis yog nruj li XHTML hu ua HTML5. Lawv cia siab tias qhov no nws thiaj li yuav yog ib qho kev pom zoo W3C.
Kev txiav txim siab ntawm Version of HTML

HTML yog ntau looser dua XHTML vim tias koj tawm mus quotes tawm cwj pwm, tawm cov cim npe nyiam
tsis muaj daim pib xaus
thiab ua li ntawd.

- HTML 4.01
Thiab qee tus neeg tawm tsam tias qhov version thib plaub yog qhov "tsis muaj-DOCTYPE" version. Qhov no feem ntau hu ua quirks hom thiab hais txog HTML cov ntaub ntawv uas tsis muaj DOCTYPE txhais thiab thiaj li xaus li displaying quirkily hauv kev sib txawv browsers.
Kuv pom zoo HTML 4.01. Qhov no yog qhov tseeb version ntawm tus txheej txheem, thiab nws yog feem ntau dav txais los ntawm cov neeg saib xyuas niaj hnub.
