DESCRIPTION OF TAGS AND ITS SIGNIFICANCE IN HTML:
WHAT IS MEANT BY TAG?
"TAG" in html is nothing but element surronded by angular brackets .
Which indicate the starting and end of content(i.e., text,images,audio,graphic content)....
Description of markup language and explaining various types of markups:
WHAT IS MEANT BY MARKUP?
Markup comprises a set of symbols, or a language, that can be used to provide instructions.
The use of markup is supported by rules that define the symbols and how they should be used: a specification.
A webpage is created by marking-up content (text, images, etc.) using the HyperText Markup Language (HTML).
The markup provides instructions to the software used for viewing a webpage (web browser) on how the page should look and work.
Html is the hypertext markup language..as everything in html is indicated with specific set of format or instructions....
Markup content may include text,images,links,graphic contents.....
HTML MARKUP:
To create an HTML document, content is marked-up into information elements.
Specific tags, denoted by characters within angle brackets, are used to signify the beginning, and end of each element.
For example, to tell the web browser that 'hello’ is a heading, the text is marked-up into a heading element, using level-one heading tags.
<h1> Hello</h1> //level -1 heading
The look of the heading, the typeface, type size and colour, are set using a separate, supplementary presentation language: Cascading Style Sheets (CSS).
HTML elements include;
Presentational markup:
Presentional tags are used in these ...like
paragraph tag<p>,
heading tag<h>
,bold tag<b>,
italic tag<i>,
underline tag<u>.....
Although the HTML language specification defines the markup that can be used to create a webpage, the webpage author decides which elements they will use to markup content.
If a webpage author is using software that enables a webpage to be edited visually, rather than at a code level, they may be more inclined to use markup that achieves a visual effect—this is referred to presentational markup.
Heading can be created with different colour ,size,different font and aligned.....
The appearance of a heading may be created by making text larger, bold and a different colour..
Heading tag<h>:
It is used to make the text as heading..
syntax:
<h1....h6> text to be appeared as heading</h1...h6>
heading tag<h>:
It consists of levels:
<h1> some text </h1> //large size text
<h2> some text </h2> //less than h1 size
<h3> some text </h3> //less than h2 size
<h4> some text </h4> //less than h3 size
<h5> some text </h5> //less than h4 size
<h6>some text</h6> //less than h5 size
//program to illustrate headings of webpage..
<HTML>
<HEAD>
<TITLE>MY WEB</TITLE>
</HEAD>
<BODY>
<h1><font size=18 color="red">THe world is so large</h1>
</BODY>
</HTML>
output:
//program illustrating presentational markup....
<HTML>
<HEAD><TITLE>MY WEB</TITLE>
</HEAD>
<BODY>
<p><font size=18 color="pink" style="bold" face="verdana">plants are wealth of nature</p>
</BODY></HTML>
output:
STRUCTURAL MARKUP:
In structural tags we use ordered and unordered tags.....
The structural markup
uses an unordered list element,
<ul></ul> and list-item elements, <li></li>
The structural markup
uses an ordered list element,
<ol></ol> and list-item elements, <li></li>
structural tags <ol> //ordered liststructural tags <ul> //unordered liststructural tags <li> //represents list
<!doctype html> is necessary to know that which type of document it belongs to...
//program to illustrate structural tags
<!DOCTYPE html> <!..doc type tells about type of the document..>
<HTML>
<HEAD>
<TITLE>MY WEB</TITLE>
</HEAD>
<BODY>
<ol>
<li>plants</li> <!..represents ordered list of data..>
<li> wealth</li>
<li> nature</li>
</ol>
<br><br>
<ul>
<li>plants</li> <!..represents unordered list of data..>
<li> wealth</li>
<li> nature</li>
</ul>
</BODY></HTML>
OUTPUT:
conclusion:
with the use of the presentational tags,structural tags with markup language... we can text to appear more attractive format.....
