An element that is associated with a tag and takes a value.

Answer:
Explanation:
his is a list of tags used in the HTML language. Each tag starts with a tag opener (a less than sign) and ends with a tag closer (a greater than sign). Many tags have corresponding closing tags which identical except for a slash after the tag opener. (For example, the TITLE tag).
Some tags take parameters, called attributes. The attributes are given after the tag, separated by spaces. Certain attributes have an effect simply by their presence, others are followed by an equals sign and a value. (See the Anchor tag, for example). The names of tags and attributes are not case sensitive: they may be in lower, upper, or mixed case with exactly the same meaning. (In this document they are generally represented in upper case.)
Currently HTML documents are transmitted without the normal SGML framing tags, but if these are included parsers will ignore them.
Title
The title of a document is given between title tags:
<TITLE> ... </TITLE>
The text between the opening and the closing tags is a title for the hypertext node. There should only be one title in any node. It should identify the content of the node in a fairly wide context, and should ideally fit on one line.
The title is not strictly part of the text of the document, but is an attribute of the node. It may not contain anchors, paragraph marks, or highlighting. the title may be used to identify the node in a history list, to label the window displaying the node, etc. It is not normally displayed in the text of a document itself. Contrast titles with headings .
Next ID
Obsolete: NeXT Browser only. May be ignored. This tag takes a single attribute which is the number of the next document-wide numeric identifier to be allocated (not good SGML). Note that when modifying a document, old anchor ids should not be reused, as there may be references stored elsewhere which point to them. This is read and generated by hypertext editors. Human writers of HTML usually use mnemonic alpha identifiers. Browser software may ignore this tag. Example of use:
<NEXTID 27>
Base Address
Anchors specify addresses of other documents, in a from relative to the address of the current document. Normally, the address of a document is known to the browser because it was used to access the document. However, is a document is mailed, or is somehow visible with more than one address (for example, via its filename and also via its library name server catalogue number), then the browser needs to know the base address in order to correctly deduce external document addresses.
The format of this tag is not yet specified. NOT CURRENTLY USED
Anchors
The format of an anchor is as follows:
<A NAME=xxx HREF=XXX> ... </A>
The text between the opening tag and the closing tag is either the start or destination (or both) of a link. Attributes of the anchor tag are as follows.
HREF
If the HREF attribute is present, the anchor is senstive text: the start of a link. If the reader selects this text, he should be presented with another document whose network address is defined by the value of the HREF attribute . The format of the network address is specified elsewhere . This allows for the form HREF=#identifier to refer to another anchor in the same document. If the anchor is in another document, the atribute is a relative name , relative to the documents address (or specified base address if any).
NAME
The attribute NAME allows the anchor to be the destination of a link. The value of the parameter is that part of a hypertext address which follows the hash sign .
TYPE
An attribute TYPE may give the relationship described by the hyertext link. The type is expressed by a string for extensibility. Strings for types with particular semantics will be registered by the W3 team. The default relationship if none other is given is void.
All attributes are optional, although one of NAME and HREF is necessary for the anchor to be useful.
IsIndex
This tag informs the reader that the document is an index document. As well as reading it, the reader may use a keyword search.
Format:
<ISINDEX>
The node may be queried with a keyword search by suffixing the node address with a question mark, followed by a list of keywords separated by plus signs. See the network address format .
Plaintext
This tag indicates that all following text is to be taken litterally, up to the end of the file. Plain text is designed to be represented in the same way as example XMP text, with fixed width character and significant line breaks. Format:
<PLAINTEXT>
This tag allows the rest of a file to be read efficiently without parsing. Its presence is an optimisation. There is no closing tag.
Example sections
These styles allow text of fixed-width characters to be embedded absolutely as is into the document. The format is:
<LISTING>
...
</LISTING>
