HTML tags can have attributes. The special attributes for each tag are listed under each tagdescription. The attributes listed here are the core and language attributes that are standard for alltags (with a few exceptions).

New to HTML 4.0 was the ability to let HTML events trigger actions in the browser, like starting aJavaScript when a user clicks on an HTML element. Below is a list of attributes that can be insertedinto HTML tags to define event actions.
If you want to learn more about programming with these events, you should study our JavaScripttutorial and our DHTML tutorial.
Window Events
Only valid in body and frameset elements
Attribute Value Descriptiononload script Script to be run when a document loadsonunload script Script to be run when a document unloads
Form Element Events
Only valid in form elements.

HTML Colors
The table below provides a list of the color names that are supported by all major browsers.
Note: If you want your pages to validate with an HTML or a CSS validator, W3C has listed 16 colornames that you can use: aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple,red, silver, teal, white, and yellow. If you want to use other colors, you must specify their RGB orHEX value.

HTML and XHTML uses standard 7-BIT ASCII when transmitting data over the Web.
7-BIT ASCII represents 128 different character values (0-127).

7-BIT ASCII Device Control Characters
ASCII device control characters were originally designed to control hardware devices like teletypes,printers and tape drives.
These characters have nothing to do inside an HTML document:

127 DEL delete (rubout)
HTML 4.01 supports the ISO 8859-1 (Latin-1) character set.
The lower part of ISO-8859-1 (codes from 0-127) is the original 7-BIT ASCII.
The higher part of ISO-8859-1 (codes from 160-255) all have character entity names.
Most of these characters can be used without an entity reference, but entity names or entitynumbers provide a method for expressing characters that cannot easily be entered on a keyboard.
Note: Entity names are case sensitive.
