An attribute supplies additional instructions
to the browser about a tag. The information varies from tag
to tag and can include such items as file locations, size,
name or style.
A Web browser is a special type of parsing
engine that evaluates the tags and contents of an HTML file
and displays it according to the capabilities and rules of
the file's own capabilities and platform.
For example, a text-only browser displays
the alternative text for an image, but a graphical browser
displays the actual image. A browser for a monochrome platform
ignores the color settings from a style sheet or renders them
as shades of gray.
| Document Type
Definition (DTD) |
A collection of rules written in Standard
Generalized Markup Language (SGML) that define the syntax
and structure of a specific type of document, such as HTML.
A distinctive component of a document's
structure, such as a title, paragraph or list. It can include
an opening or closing tag and the content within it.
A markup element is usually enclosed in
a pair of start and end tags. The ELEMENT statement in SGML
defines both start and end tags (but not their attributes)
and prescribes what might be the content of this element by
defining its content model.
Example:
<! ELEMENT P - O (%inline;)*
-----paragraph----->
Here, P is the element name (short for Paragraph).
The two characters following the element name are minimization
indicators specifying whether it is possible to omit start
and \ or end tags for this element. The first indicator refers
to the start tag and the second to the end tag.
A piece of text that usually identifies
an element so that a browser or other parser knows how to
display its contents. Tags are surrounded by special delimiter
characters (angle brackets).
The HEAD element of a document is marked
by an opening <HEAD> and closing
</HEAD> tag.
Many advanced techniques like making your
website interactive, requires using Scripting languages. Some
of script related software is JavaScript, Jscript, VBScript.
