If you are viewing this document using Netscape and would like to see the HTML source producing this display select View on the menu bar and then Source from the drop-down menu.
If you are using Mosaic and would like to see the HTML source producing this display select File on the menu bar and then Document Source from the drop-down menu.
The above table of contents is an unordered list. Each element is a hyperlink in the form of:
<A HREF=#branch-name>branch-title</A>
The target anchor is in the form of:
<A NAME=#branch-name>display-anchor-title</A>
<A HREF=[transfer-protocol][web-location]resource-name> anchor-prompt</A>
The table of contents in this document uses internal links. There are two components required, the pointer and the branch location within the document. The pointer takes the form of:
<A HREF=#branch-label>title</A>
The pointer to this section is:
<A HREF=#SAME>To other places within the Same Document</A>
The desired location tag pair takes the form of:
<A NAME="branch-location"><title</A>
The target tag pair for this section is:
<A NAME="SAME"><Links to other places within the Same Document</A>
If the desired resource is located at the same Web site and uses the same protocol, all that is needed is the name of the resource. This pointer takes the form:
<A HREF=resource-name>anchor-prompt</A>
To illustrate, a file named SECOND.HTM which is located at the same site and in the same directory as the document currently being viewed would be fetched using the link:
<A HREF=SECOND.HTM>Click here to activate SECOND.HTM</A>
An external link points to a resource at another Web site. As an example, my home page link is:
<A HREF=HTTP://www.charm.net/~lejeune>Urb's Home Page</A>
It would appear on you screen as: Urb's home page
Most Web pages consist of plain text, which is any text appearing outside of an attribute tag pair. Web viewers ignore multiple spaces, tabs, and line breaks while "word-wrapping" text. You have no control over the display of plain text. If you desire a line break inserted in your text use the <BR> tag. To force a paragraph use the <P> tag.
Line one. <BR> Line two. <P> appears as:
Line one.
Line two.
If text is to be display with formatting retained, as an example a program listing, use the <PRE> </PRE> tag pair.
Paragraphs are not indented, however, multiple blanks are inserted using a series of " " groupings. This paragraph starts with two such groupings.
This sentence is normal text. Each of the following styles is enclosed between the tags indicating the style. Emphasized Text
Strong Text
Cited Text line break is next.
Bold Text
Italics Text
Underlined Text
Typewriter Font
Horizontal Rule <HR> is next
An inline graphic is treated like a character, albeit a very large one, by graphical WWW browsers. The format for displaying an inline image is
<IMG [ALT="alternative-text"] [ALIGN=text-position] SRC=url-of-graphic>
Where "alternative-text" is the text that will be displayed, in lieu or the image on a non-graphic browser such as lynx.
The parameter for ALIGN= may be TOP, CENTER, or BOTTOM. This determines where one line of text will be display within the same paragraph.

A thumbnail sketch is small graphic display that points to a larger version of the same graphic. It has the advantage of not requiring the full graphic to be transmitted and displayed unless the user specifically requests the larger display.
<A HREF=large-graphic-file><IMG SRC=graphics/thumb-nail-graphic-file> </A>
Click on the thumbnail graphic to activate a larger graphic.
The heavy border around the graphic indicates that the image is
a pointer.
These characters are formed using either the "&special-name;" or the "&#nnn;" (where nnn is the numeric code) format conventions. As an example the double quote is " and the Yen symbol (¥) is "¥ ;".

Netscape has added a series of enhancements to the existing HTML standard. Be aware, the use of these additional constructs are NOT supported by other browsers. Check the effect of these tags when viewing documents using other popular browsers before adopting.
The most popular of Netscape's enhancements is the text centering.
Centering Example The above example is produced by
<CENTER><IMG SRC=home.gif> <B>Centering Example</B></CENTER>
Blink is the most derided Netscape's enhancement. People either love it or hate it, with the later predominating. Use it sparingly.
Dude
The above example is produced by
<BLINK><B>Cool</B></BLINK> Dude
Both Center and Blink can be used with relative impunity. If a browser doesn't support the enhancement it is ignored. The text will still be produced, without the centering or blinking.
Font size can be changed on the fly using the FONT tags in the form:
<FONT SIZE=N>text</FONT>
Where N is an integer between 1 and 7 with 3 being the default.
The following examples were started with:
<FONT SIZE=1>One</FONT><BR>
Through
<FONT SIZE=7>Seven</FONT><BR>
One
Two
Three
Four
Five
Six
Seven
An interesting (?) effect is produced when placing varying font
sizes on the same line, as in the following example. The first
letter is FONT SIZE=1 and each letter increases by one through
7 and then decreases by 1.
ABC DEF G HIJ KLM
Font size may also be changed using the BASEFONT tag <BASEFONT SIZE=N>, where N in an integer in the range of 1 to 7 which represent the range of font sizes. The sizing integers are identical to the font sizes produced by the FONT SIZE pair. A major difference is the absence of a closing tag. Once the font size is changed it remains in effect until a new BASEFONT tag appears. If there is an embedded FONT SIZE pair, the font size returns to the stated BASEFONT size following the closing </FONT> tag. I would strongly suggest that you either don't use this enhancement -- since it tends to be at odds with conventional HTML matching tag pair wisdom -- or that your immediately enter a <BASEFONT SIZE=3> as a pseudo closing tag which will set the font size back to normal.
<FONT SIZE=4>
Embedded FONT SIZE=4 pair</FONT>
This line follows the embedded tag pair and is back to the BASEFONT
size of 1
Stayed tuned. More Netscape HTML enhancements are on the way.
