The Basics

Terminology

Syntax
Basically it is the way something is said.
For example: In English a person says an apple not a apple.
Deprecated
In programming this means something should no longer be used. While it works now, eventually it might not be supported.
Nesting
This means putting a lower level element inside a higher level element.
Tags
These are basically instructions that tell a browser what to do with the tag contents.
Rendered
How things are interpreted and displayed by a browser.
( *note-this has other meanings when not refering to HTML or scripts. )
Attribute
When refering to HTML an attribute is a characteristic that identifies or helps control the tag and its contents.

Basic Rules for Good Coding Practises

  1. HTML tags should be lowercase.
  2. All tags should be closed. ( example: <tag> </tag> or <tag /> )
  3. Tags should be nested and indented for clear reading.
    example:
    <parent_tag>
	<child_tag> </child_tag>
</parent_tag>
  4. Deprecated tags should not be used. ( example: <center></center> )
