HTML - Hypertext Markup Language

A webpage is practically a text or notepad document that contains the information for the web browser. The information contains tags which shows the insructions to the browser.

Tag - basics

Tags-> are < & > they start with < and end with >. the information inside the tag determines the indtructions for the browser.
Most tags have a start and end. the difference between start and end is the end tag has a slash Text inside the tag is case insensitive.

"< HTML >"
"< / HTML >"

--used to mark the mark the beginning and the end of an HTML document

Head & Body

All HTML document have two parts - head and body.
Head - information needed at the start - defines "thing" (more latter!).
Body - information for the main part of the web page - text and graphics.

Head

"< head >"
"< / head >"

Include the title of the HTML document, which appears in title bar of the web browser,
using: "< title >" "< title >"
Include comments about who created document when, purpose, etc.,
"< !-- -- >"

Also, in this unit we learned how to analyse and design a Problem-Defenition Table, Input-Processing-Output Chart, Pseudo Code and last but no least the Flowchart.

Below there is an example of these:
