Hi, you can also omit the html tags themselves in html pages.
HTML is pretty 'robust', that is people do not have to write it perfectly for
it to work!
Thus, it tolerates both upper and lower case letters and other things (other
languages, such as xhtml, are to my understanding, quite a bit stricter).
So what it is is html is not that strict.
It's sloppy coding to omit the html tag specifying the version--but it works;
it's sloppy coding (but sometimes necessary if your web host truncates the
headings of html pages and just embeds the rest in its own page with its own
heading) to put css style codes and JavaScript functions in the body itself,
but it all works fine; you just need the page content and the page saved with
the suffix .html or .htm
That's it.
Of course, there are some tags that need closing tags to get the page to format
properly (but not the head or body tags)--these include the tags denoting
lists, and tags for links.
I hope that answers your questions.
(But if you want a nicely encoded page where people can easily find style codes
and JavaScript functions, then you should put those at the bottom of the header
section and use tags to indicate the different sections, head, body, various
divs within the body; your coding shows your page structure--your headers
indicate page titles and titles of sections depending on the level header.
It's really important to use the appropriate level of headers and to divide
content up into divs in case the page is to be translated into audio . . . so
that it's clear to anyone/anything reading the code what the headers go with.
I think that is what the w3c says; someone correct me if I am wrong about this)
Best,

Subject: Technical information (DTD 4.01) : Is it possible to omit HEAD and/or
BODY tags within HTML tag ?
Dear W3C,
I just can’t understand how it’s possible to omit HEAD and/or BODY tags within
HTML tag.
I have extract those tag declaration from the HTML 4.01 DTD.
O O (%head.content;) +(%head.misc;) -- document head -->
O O (%block;|SCRIPT)+ +(INS|DEL) -- document body -->
O O (%html.content;) -- document root element -->
The HTML tag declaration specifies that HEAD and BODY tags are mandatory within
the HTML tag itself, and in that specific order, but in the HEAD and BODY tags
declarations, it’s possible to ommit those tags in the HTML document ? How can
that be ?
Also, why is the ‘+’ operator before the ‘(%head.misc;)’ and ‘(INS|DEL)’
statements instead of after, like in the ‘(%block;|SCRIPT)+’ statement ? Doest
it change the behavior of the ‘+’ operator ? Or its meaning ? I could not find
any documentation on that syntaxe.
See, for my work, I have to fully understand the HTML 4.01 DTD.
To accomplish that I looked for documentation about DTD editing on the
internet, so I could understand how yours are written.
I found what appears to me some incomplete documentation. I asked adviced to
people in my professional circle, but no one could provide me with an answer.
Could you explain to me how I should have interpreted those preceding DTD
statements ?
Or do you have any detailed DTD editing documentations, references, … I could
refer to, so I would have all the knowledge to fully understand the HTML 4.01
DTD ?
Thanks for your concern

French version of the preceding email :
Bonjour,
Je n’arrive pas à bien comprendre les extraits suivants de la DTD de la
spécification du HTML 4.01, en ce qui concerne la possibilité d’omettre les
balises HEAD et/ou BODY, à l’intérieur de la balise HTML.
O O (%head.content;) +(%head.misc;) -- document head -->
O O (%block;|SCRIPT)+ +(INS|DEL) -- document body -->
O O (%html.content;) -- document root element -->
La déclaration qui concerne la balise HTML spécifie que les balises HEAD et
BODY sont obligatoires, et dans l’ordre spécifié.
Toutefois, dans les déclarations des balises HEAD et BODY, il est aussi
spécifié que l’on peut omettre ces balises.
Comment cela est-il possible si les balises HEAD et BODY sont requises à
l’intérieur d’une balise HTML ?
Aussi, pourquoi l’opérateur ‘+’ est-il placé avant les déclarations
‘(%head.misc;)’ et ‘(INS|DEL)’, au lieu d’après, comme dans la déclaration
suivante ‘(%block;|SCRIPT)+’ ?
Est-ce que cela change le comportement de cet opérateur ? Ou sa signification ?
Je n’ai point trouver d’informations sur cette syntaxe particulière.
Voyez-vous, pour mon travail, je me dois de comprendre parfaitement la DTD de
la spécification du HTML 4.01
Pour ce faire, j’ai recherché sur internet comment éditer une DTD, afin de
pouvoir ainsi comprendre la DTD de la spécification du HTML 4.01
J’ai trouvé certaines documentations, mais de manière générale, elles me
semblent toutes incomplètes.
J’ai aussi sollicité mon entourage professionnel, sans plus de succès.
Pourriez-vous m’expliquer comment je devrais interpréter les spécifications
ci-haut ?
Ou pourriez-vous me fournir, ou me diriger, vers une documentation détaillée
d’édition d’une DTD, afin que je puisse avoir toutes les notions nécessaires
pour bien comprendre celle du HTML 4.01 ?
Bien à vous
