Before we get into any 'coding'

We need to learn what HTML really, is.

HTML

What is HTML?

HTML or HyperTextMarkupLanguage is a type of markup language used to create and design websites.

HTML Versions Uses
HTML 2.0 Basic text implementation, tables, image maps.
HTML 3.2 Dropped all math equasions, added

<blink>Element</blink>

Blink element removed a few months later due to Microsoft licensing agreement.

HTML 4.0 Comes in three different variations: Strict, Transitional and Frameset. Inherited many browser-specific element types and attributes.
HTML 4.01 Minor improvements offers the same three variations as the last version.
ISO/IEC 15445:2000 Published as an ISO/IEC international standard. After HTML 4.01, no new versions were created for many years. XML based versions XHTML was the main use of web development for many years.
HTML 5.0 HTML 5.0 is the standard for web development currently. It added many differnet things, like video players and audio players.

Of course between these there were many spinoffs including many versions of XHTML (an XML based markup for different types of development.)

Javascript

What is JavaScript?

JavaScript is a scripting language originally made to implement directelly for web development, and used to create interactive websites.

JavaScript is no longer dependant on HTML to run and is used by itself to create and run many different things.

JavaScript can be used in a certain way to add HTML and CSS into the webfile, that isn't permanent.

For example:

1

document.write("Hello");


1

Hello

My name's Phil and i am living in my grandmothers basement. I would really like to see some sun.
