Appendix A: Tag Summary

Base tag (<BASE>)

Used to define the document's original location (with use of the HREF attribute).

Character Entities (<&code;>)

Entities are used to display non-English characters and symbols which are found in the ISO Latin-1 character set. Not every entity will display correctly in every browser, although they should.

Code style tag (<CODE>)

Defines enclosed text as being a fragment of code from a program. Usually displayed in a monospaced font.

Form tag (<FORM>)

The container which defines an interactive form. These forms allow the user to input data, select from lists of choices, and so on; the data which is input must be processed by a CGI program. The results will depend on the program's instructions.

Keyboard style tag (<KBD>)

Defines enclosed text as being an example of user input. Usually displayed in a monospaced font.

Input tag (<INPUT>)

The most common form element, INPUT has several different types. These are:

Text

An open box where the user can tye anything from the keyboard

Radio

Presents a number of choices, any one of which may be selected by the user

Checkbox

Presents a number of choices, any number of which may be selected by the user

Hidden

Allows the author to invisibly pass information to the back-end CGI program

Password

Displays input as a series of bullets or asterisks; does not encrypt the data which is entered

Submit

Creates a mechanism for the user to indicate that the form should be processed by its back-end CGI script

Reset

Creates a mechanism by which the user can reset the form to its default state, wiping out any changes the user has made

Meta tag (<META>)

Used to define information which cannot be otherwise defined using existing HTML tags, such as author name, expiration date, or anything else the author can think of.

Option tag (<OPTION>)

Defines an option in a SELECT list.

Preformatted text tag (<PRE>)

 

Sample style tag (<SAMP>)

Defines enclosed text as being a string of literal characters-- the browser should display them verbatim. Usually displayed in a monospaced font.

Select tag (<SELECT>)

Creates a list, either pop-up or scrollable, from which the user can select one or more options (if the MULTIPLE attribute is used).

Textarea tag (<TEXTAREA wrap>)

Creates an area where the user can input a large amount of text across multiple lines.
