Knowledge Never Sets
As we have already seen the structure of html document. The root of the document is html tag then there are two child tags head and body.
Head tag contains meta data of a web page like title, meta,link,base.
Syntax
1 2 3 4 5 6 7 8 9 | <html> <head> . . </head> <body> </body> </html> |
Example
1 2 3 4 5 6 7 8 | <html> <head> <title>My First Page</title> </head> <body> Hello How are you. </body> </html> |
To show data in subscript and in superscript format we use <sub>..</sub> and <sup>..</sup> tags.
1 2 | X<sup>2</sup>+Y<sup>2</sup> H<sub>2</sub>O |
Example:
Output:
X2+Y2
H2O
For creating bold Itelic and Underline text we use following syntax.
We can also use nesting of tags
Example:
1 2 3 4 | <b>This is a bold text</b> <i>This is a italic text</i> <u>This text is a underline</u> <b><i>This is a bold and italic text</i></b> |
Output:
This is bold text
This is italic text
This text is underline
This is bold and italic text
General HTML 5 Document Structure is as below
1 2 3 4 5 6 7 8 9 | <!DOCTYPE html> <html lang="en"> <head> ... </head> <body> ....... </body> </html> |
<!DOCTYPE html> specifies that this document is html 5 document and you can use all html5 tags here.
<html> is root tag of html document it contains two child tags <head> and <body>
<head> specifies that this portion contains heading information of page we can use many other tags here like <title> which is used to specify the title of page and may other.
<body> we put the contents which you would like to display on browser.
Inside body tag we use many different html tags to proper formatting the data.
