Se uso firefox e vado nell'html validate mi porta solo due errori

Below are the results of attempting to parse this document with an SGML parser.

1. Error Line 24 column 163: character data is not allowed here.

...Contemporanea" />

You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include putting text directly in the body of the document without wrapping it in a container element (such as a

aragraph</p>) or forgetting to quote an attribute value (where characters such as "%" and "/" are common, but cannot appear without surrounding quotes).

✉
2. Error Line 47 column 3329: there is no attribute "NAME".

... src="banner/arrows.gif" alt="" name="undefined_2" width="8" height="8" class

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).
Ma se uso IE e vado a validare mi porta questo risultato

Result: Failed validation
File: C:\Documents and Settings\Sonia\Desktop\template.html
Encoding:
Doctype:

Sorry, I am unable to validate this document because its content type is text/plain, which is not currently supported by this service.

The Content-Type field is sent by your web server (or web browser if you use the file upload interface) and depends on its configuration. Commonly, web servers will have a mapping of filename extensions (such as ".html") to MIME Content-Type values (such as text/html).

That you received this message can mean that your server is not configured correctly, that your file does not have the correct filename extension, or that you are attempting to validate a file type that we do not support yet. In the latter case you should let us know that you need us to support that content type (please include all relevant details, including the URL to the standards document defining the content type) using the instructions on the Feedback Page.
perchè?
uso firefox per validare e faccio finta di niente?
