Valid HTML is HTML that has been coded with adherence to standard specifications set forth by the World Wide Web Consortium (W3C.) The standards vary from version to version, but you can use the W3C's validator to see if a given file is valid.
You can find a link to the Validator in the Related Links section.
The requirement for a valid XHTML is that all the tags should be closed. This is actually the difference between HTML and XHTML.
Some versions are not just similar to, but actually valid, XML (extensible markup language.) HTML also bears a resemblance to the my older SGML.
<sub>Your Subscript Here</sub> The <sub> tag is used to surround subscript. It's cousin, that <sup> tag is used in the same way to surround superscript. Both tags are valid in HTML 4, HTML 5, and XHTML.
RPC stands for Remote Procedure Call, and is used to cause the remote invocation of computer programs. Therefore, RPC is not a valid email format.
HTML markup validation is a process by which the HTML standard DTD (Document Type Definition) is applied to an HTML document. If the document follows the rules laid out by the standard, the document is said to be valid. Should a document fail the test, it's deemed invalid. This process is normally conducted by a computer program. Because the standards are produced by the W3C, their validator is the de facto standard, although, due to the open nature of the standard, other validators exist. Invalid code causes the browser to go into "quirks mode" and makes how the browser renders the code a "best guess" situation. Producing valid code ensures that it will be treated in a standard way by all browsers. (In other words, at least you'll know what bugs you might run into with valid code.)
No. Valid HTML requires at least these tags:HTML example... content goes here ...The body content can be plain text. But after adding these tags, the document is not plain text anymore.
PHP files are HTML files with any amount of PHP intermingled into it, so the file can be empty or only contain HTML and be valid, yes.

Every HTML and XHTML page must have at least 4 elements to be considered valid by the W3C. Those elements are HTML, HEAD, BODY, and the HEAD child TITLE. Furthermore, the standards define that the there must be one and only one of both the HEAD and BODY tags, and that they must be the direct children of the HTML element. They also must come in that order (HEAD, then BODY.)

You can do this using the "target" attribute of the anchor tag. It looks like this:Your linked textThe target attribute is valid in HTML 4 and 5, but was deprecated in XHTML 1.0, so it's not valid in the "Strict" doctype (use transitional instead.)
<html> <title>This will change the tab text at the top of the page</title> <body> </body> </html> These are your basic tags for creating a webpage, any thing less than this here will not be considered valid, and will throw the browser into Quirks Mode.
