What is HTML
Part III

Tags can enter the name with parameters or attributes. Sets of allowable parameters are individual for each tag. Common rules are the following: tags are separated by spaced. Many parameters demand the instruction of their values, however some parameters have no values or can enter the name without them, accepting values by default. If the parameter demands value it is underlined after the name of parameter through an equal-sign. The value either may be used with parameter or without. We shall result an example of record of a tag with parameters:

Here for a tag <TABLE> it is set two parameters. The first parameter BORDER is specified without value. The second parameter ALIGN matters left.

We shall mention here the general parameters of tags not to speak about them at the description of each tag.

All tags which is allowable to use in section <BODY> document HTML, can have parameters CLASS, ID, LANG, LANGUAGE, STYLE and TITLE. Use of these parameters is useful, first of all, at style official registration of papers.

Parameters CLASS, ID, STYLE are supported Internet Explorer, since version 3.0, and Netscape, since version 4.0. These parameters are necessary at use of styles.

Parameters LANG, LANGUAGE, TITLE - are supported only Internet Explorer, since version 4.0. These parameters specify, accordingly, used language, language of record of scripts (for example, LANGUAGE=JavaScript), and also the text of the help which are given out at prompting of the index of the mouse on the given element (TITLE).

In modern HTML, besides tags of language and their contents, in an initial HTML-code codes of scripts (javascript or VBScript) also enter the name.

Finishing general review HTML, we shall note, that the elementary HTML-documents represent usual text files, for viewing and which editing it is possible to take advantage of any text editor. These files usually have extension HTM or HTML.
