errore al validatore W3C che significa?

qualcuno mi sa spiegare questi errori per poi poterli correggere ? il link è questo

<div id="main"> ✉
Line 168, Column 11: end tag for element "div" which is not open.
</div></div>✉
The Validator found an end tag for the above element, but that element is not currently open. This is often caused by a leftover end tag from an element that was removed during editing, or by an implicitly closed element (if you have an error related to an element being used where it is not allowed, this is almost certainly the case). In the latter case this error will disappear as soon as you fix the original problem.

If this error occurred in a script section of your document, you should probably read this FAQ entry.

Line 9, Column 72: end tag for "meta" omitted, but OMITTAG NO was specified.

Codice sbagliato:

codice:

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

Codice corretto (in XHTML i tag si chiudono così)

codice:

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>

L'errore alla linea 10 è analogo.

Per gli altri errori: hai dimenticato di aprire il tag <body> dopo </head>.

Io ho corretto! ma mi da altri errori!

Sbagliato

codice:

<link rel="stylesheet" type="text/css" href="style/style.css /">

Corretto:

codice:

<link rel="stylesheet" type="text/css" href="style/style.css" />

allora correggendo qello e inserendolo da solo il validatore dice OK! ma se inserisco gli altri tag mi danno tutti errore come mai ? eppure ho applicato gli stessi parametri del " e lo spazìetto con la chiusura larga...

Line 10, Column 11: there is no attribute "NAME".
<META NAME="TITLE" CONTENT="casartigiani" /> ✉
You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash.

by using vendor proprietary extensions such as "<spacer>" or "<marquee>" (this is usually fixed by using CSS to achieve the desired effect instead).

The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

Ti mancano i tag <html>e <head>.

codice:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html>
<head>

PS: il tag CODE....

**decori** · 08-09-2007, 17:29

Guarda che non è proprio così perchè controlla pure al link

inserendo il tag HTML non funziona nulla e mi da 21 errori!

<html>
<head>

Ogni volta che visito il tuo sitio e guardo il codice, risolvi un errore e ne metti un altro...

PS: per certi errori basta leggere quello che dice il sgnor W3C. Partendo dal primo, perché quelli successivi possono essere errori in cascata. Leggi il primo errore, lo risolvi, rieffettui la validazione, riguardi il primo degli errori (se ce ne sono ancora), risolvi l'errore ecc... finché non otterrai 0 errori.

Line 6, Column 5: document type does not allow element "html" here.

Cosa significherà mai?

alloa Panta...non è per nulla ma io ho provato a caricare la pagina con il tag HTML e senza. Adesso è senza ma mi dà una serie infinità di errori lo stesso ...che vorrà dire mai?

codice:

 <style type="text/css" media="all">@import "./style/base.css";
            @import "./style/results.css";</style>

Per forza... Metti a posto questa cosa, non toccare nulla e vedrai che va a posto!

codice:

  <meta name="keywords" content="HTML, HyperText Markup Language, Validation,
      W3C Markup Validation Service" />
    <meta name="description" content="W3C's easy-to-use
      HTML validation service, based on an SGML parser." />

Piccola annotazione. Andare a capo in un tag non è consigliato (semanticamente errato).
