Components of HTML

There are three foundational components of HTML.

• Tags
• Attributes
• Values

TAGS

The main part of HTML command is tag (technically it is referred as elements) HTML documents are defined by HTML elements.

Tag is a identity of html tag says to "do this". modifications makes tag powerful. and these modifications are done by attributes.

There are general rules about html tags...

1.All standard tags are contained within the less than(<) and greater than(>) symbols as follows

called opening tag.

2.There are no space between the the symbols and the tags .as follows

3.Add a forward slash before the tag to denote the tag closure. as follows

called closing tag.

4.There must be closing for every opening tag.

ATTRIBUTES

Attributes modify the action of tags. some tags works properly without attributes but some requires attributes for function. as

tag and its companion closing tag needs no attribute because this is just to  tell about the  beginning  of html document and ending of it.

but tag and its companion tag needs attribute because this tag denotes the area of  html document that will be viewed within the browser .attributes are often whole words some times they are partial words. whole word attributes include align ,link, color and face.

partial word examples are src for "source" ,and "vlink" for visited links  .

VALUES

Values are the defining aspects of attributes and they modify the tags. several values for align tag are left ,right ,center and justify.

let us understand it in terms of font a font requires some size and some color .the value which we pass for color and size are called the

values for the attributes size and color.

eg. this is some text

here is a tag

size and color are the attributes and 3 and red are the values of attributes.

here is the example to understand the difference between tag ,attribute and values

Difference Between HTML And DHTML?

HTML:

1. Html stands for Hyper Text Markup language.
2. The pages of the site do not require any special
processing from the server side before they go to the
browser. Means the pages are always the same for all
visitors - static.
3. html does not allow any kind of features.
4. Html sites going solely upon client-side technologies.
5. HTML is a language.
6. HTML documents describe web pages, contain HTML tags and
plain text.

DHTML:

1. Dhtml stands for Dynamic Hyper Text Markup language.
2. DHTML uses client side scripting to change variables in
the presentation which affects the look and function of an
otherwise static page.
3. DHTML allows us some extra features.
4. Dhtml sites going fast upon client-side technologies.
5. DHTML is not a language or a web standard.
6. DHTML is the art of combining HTML, JavaScript, DOM,

Introduction Of HTML,What HTML stands for?

HTML stand for Hyper Text Markup Language :

Hyper is the opposite of linear. It used to be that computer programs had to move in a linear fashion. This before this, this before this, and so on.
HTML does not hold to that pattern and allows the person viewing the World Wide Web page to go anywhere, any time they want.
Text is what you will use. English letters, just like you use everyday..
Markup is what you will do. You will write in plain English and then mark up what you wrote.
Language. Some may argue that technically html is a code, but you write html in plain, everyday English language.

HTML stands for HyperText Markup Language. Developed by scientist Tim Berners-Lee in 1990, HTML is the "hidden" code that helps us communicate with others on the World Wide Web (WWW).

When writing HTML, you add "tags" to the text in order to create the structure. These tags tell the browser how to display the text or graphics in the document.

As It is explained in the Venn diagram XHTML is a subset of HTML and XML.
XHTML combines the flexibility of HTML with the extensibility of XML.
