This appendix contains an alphabetical listing of some common XHTML tags and attributes - for a full list visit
A (anchor or link)
The A tag lets you define anchors and links.
Syntax
...
Attributes:
HREF="Location" required for a link
NAME="AnchorName" optional (and uncommon) in a link
ONCLICK="clickJScode"
ONMOUSEOUT="outJScode"
ONMOUSEOVER="overJScode"
TARGET="WindowName"
HREF="Location" specifies a destination URL for the anchor or link.
NAME="AnchorName" specifies a name for the anchor. A link to the anchor uses this value for its HREF attribute.
ONCLICK="clickJScode" specifies JavaScript code to execute when a user clicks the image or link text. See the JavaScript Guide for information on event handlers.
ONMOUSEOUT="outJScode" specifies JavaScript code to execute when a user moves the mouse pointer out of the image or link text. See the JavaScript Guide for information on event handlers.
ONMOUSEOVER="overJScode" specifies JavaScript code to execute when a user moves the mouse pointer over the image or link text. See the JavaScript Guide for information on event handlers.
TARGET="WindowName" is only used if the anchor is also a link. It specifies the window that the link is loaded into. Navigator 2.0.
ADDRESS (format as address)
The ADDRESS tag displays address information in a format determined by each browser (Netscape Navigator displays addresses in italic). An address can include authorship information and is usually placed at the top or bottom of a document.
Syntax
...
AREA (client-side image maps)
The AREA tag defines a client-side image map. An image map is a graphic that has clickable regions that link to different URLs. For example, you can have an image with a square and a circle where a click in the square takes you to one page and a click in the circle takes you to a different page.
Different areas of an image map can jump to different Web pages.
Client-side image maps are defined by MAP and AREA tags. When a user clicks the image, Navigator determines what URL to load based, on the information in the AREA tag. The USEMAP attribute of the IMG tag specifies an image as a client-side image map. The MAP tag contains one or more AREA tags. Each AREA tag describes a different region as a hyperlink in the image and specifies the URL to which it connects.
Syntax
Attributes:
COORDS="x1,y1,x2,y2,..." required
|"x-center,y-center,radius"
HREF="Location" required
NAME="areaName"
NOHREF
ONMOUSEOUT="outJScode"
ONMOUSEOVER="overJScode"
SHAPE="CIRCLE"|"RECT"|"POLY"|"DEFAULT"
TARGET="WindowName">
COORDS specifies the coordinates of the region defined by the AREA tag.
HREF="Location" specifies the URL of the document to load when a user clicks the area.
NAME="areaName" specifies the map name to be used with the USEMAP attribute of the IMG tag. The value of the areaName must begin with an alphanumeric character.
NOHREF specifies that no URL is loaded when a user clicks the area.
ONMOUSEOUT="outJScode" specifies JavaScript code to execute when a user moves the mouse pointer out of the image or link text. See the JavaScript Guide for information on event handlers.
ONMOUSEOVER="overJScode" specifies JavaScript code to execute when a user moves the mouse pointer over the image or link text. See the JavaScript Guide for information on event handlers.
Defining regions in an image
SHAPE specifies the shape of the map. Each shape has its own form of the COORDS attribute:
•circle URL x,y,x,y specifies a circle. Circles need two coordinates the first pair identifies the circle center and the second identifies any point on the circle's edge. •rect URL x,y,x,y specifies a rectangle by its upper left (first pair) and lower right corners. •poly URL x,y,x,y specifies a polygon of up to 100 sides. Each x,y pair is the point where two sides of the polygon meet. The last x,y pair is connected to the first to enclose the polygon. •default URL defines the URL to jump to when someone clicks in an area not specified by any regions. If you use a point in the map file, then the default is never used.
If no SHAPE is defined, RECT is used.
TARGET="WindowName" specifies the frame or window that the linked URL is loaded into. When a user clicks an area that has a TARGET attribute, the URL is loaded in the specified window or frame instead of in that containing the area. Navigator2.0.
B (boldface)
The B tag displays text in boldface.
Syntax
...
BLOCKQUOTE (indent block of text)
The BLOCKQUOTE tag indents a block of text. Use the BLOCKQUOTE tag for longer quotations, and the CITE tag for short quotations.
Syntax
...
BODY (main content of document)
The BODY tag specifies the main content of a document. Each HTML document begins with a ..., then concludes with a ....) Within the body of your document you can include the tags that define global characteristics of the document the layout and structure of the document and all links to text and graphics.

BR (line break)
The BR tag breaks the line in the text flow of your document. This lets you control where the next line of text appears, which is especially useful when including graphics in a document. Unlike the P tag, the BR tag does not add extra space.
The BR tag does not require a closing tag.
Syntax
CENTER (center a block of text)
The CENTER tag centers the enclosed block of text.
Syntax
...
CITE (citation)
The CITE tag marks a block of text as a citation. The citation should be a small citation, such as a book title. Use the BLOCKQUOTE tag for long quotations. Netscape Navigator displays citations in italics.
Syntax
...
DD (definition description)
The DD tag marks a definition in a definition list. The DD tag must be used within the scope of a DL tag and should be used in conjunction with the DT tag (the term being defined). The DD tag does not require a closing tag.
Syntax
…
DIV (section of a document)
The DIV tag encloses a division of a document, such as a chapter, appendix, or section, enabling you to apply alignment to all paragraphs in that division.
Syntax
…
Attributes:
ALIGN specifies the horizontal alignment of the division. The value can be:
•LEFT aligns the division flush left (the default). •CENTER centers the division. •RIGHT aligns the division flush right.
DL (definition list)
The DL tag encloses a definition list. A definition contains terms and definitions. Netscape Navigator displays the terms left aligned and the definitions indented on the next line.
Syntax
......
COMPACT "compacts" the definition list by placing the term defined by the DT tag on the same line as the definition defined by the DD tag, provided the term is short enough.
DT (definition term)
The DT tag specifies the term defined in a definition list. The corresponding DD tag specifies the definition. The DT tag does not require a closing tag.
Syntax
…
FONT (change color, face, size)
deprecated
The FONT tag lets you change the color, size, and face (font family) of the font. You can specify the default font size for a document using the BASEFONT tag. The FONT tag overrides any other font settings. In other words, text within the scope of the FONT tag is displayed in the color and size you specify, regardless of any other settings.
Syntax
...
Attributes:
COLOR="color"
FACE="fontlist"
SIZE="fontSize"
COLOR="color" defines the desired text color. The color value is a hexadecimal red-green-blue triplet, or a color name. See Appendix B, "Color values."Navigator 2.0
FACE="fontlist" specifies a comma-separated list of fonts as your preferred font choices for the text in the scope of the FONT tag. Navigator searches for the first font in the list; if the font is present, Navigator uses it; otherwise the search continues. If none of the fonts is found, Navigator 3.0
SIZE="fontSize" defines the size of the font, in a range from 1 to 7, with a default size of 3. You can also specify the size using a plus or minus sign in front of the number to change the size with respect to the base font size.
FORM (create form)
The FORM tag creates an HTML form, which lets users input text and make choices from elements such as checkboxes, radio buttons, and selection lists. A user fills out the form, and then submits the form by clicking a button.
You define and specify the features of a form by using the following tags nested within the FORM tag:
•INPUT •SELECT •TEXTAREA
Syntax
...
Attributes:
ACTION="ServerURL" required, if any action is to occur
ENCTYPE="EncodingType"
METHOD="GET"|"POST"
NAME="FormName"
ONRESET="resetJScode"
ONSUBMIT="submitJScode"
TARGET="WindowName"
ACTION="ServerURL" specifies the URL of the server where the form information is sent. This attribute can specify a CGI or LiveWire application on the server; it can also be a mailto: URL if the form is to be mailed to someone.
ENCTYPE="EncodingType" specifies the MIME encoding of the data sent:
•"application/x-www-form-urlencoded" (the default), is typically used if METHOD attribute has the value "POST" •"multipart/form-data" is used when the form contains a file upload element (INPUT TYPE="file").
METHOD specifies how information is sent to the server specified by ACTION.
•GET (the default) appends the input information to the URL which on most receiving systems becomes the value of the environment variable QUERY_STRING. •POST sends the input information in a data body that is available on stdin with the data length set in the environment variable CONTENT_LENGTH.
NAME="FormName" specifies the name of the form. The name is not displayed on the form. Since there can be multiple forms on the same page, the NAME attribute is used by JavaScript to differentiate different forms.
ONRESET="resetJScode" specifies JavaScript code that executes when a user resets the form, as with a RESET button. See the JavaScript Guide for information on event handlers.
ONSUBMIT="submitJScode" specifies JavaScript code that executes when a user submits the form, as with a SUBMIT button. See the JavaScript Guide for information on event handlers.
TARGET="WindowName" specifies the window that form responses are displayed in. When a user submits a form with a TARGET attribute, server responses are displayed in the specified window instead of the window that contains the form. Navigator 2.0.
FRAME (create an independent window region)
The FRAME tag creates a frame, which is an individual, independently scrolling region of a web page. The FRAMESET tag defines a group of frames that display in one Netscape Navigator window. The FRAME tag defines each individual frame in the Netscape Navigator window. Each frame can be defined with unique features and characteristics using the FRAME tag's attributes.
The content that each frame displays is determined by a distinct URL. Links in a frame can cause a related frame to point to a different URL, and frames can be targeted by other URLs within the same window.
Syntax
Attributes:
BORDERCOLOR="color"
FRAMEBORDER="YES"|"NO"
MARGINHEIGHT="pixMarHeight"
MARGINWIDTH="pixMarWidth"
NAME="frameName"
NORESIZE
SCROLLING="YES"|"NO"|"AUTO"
SRC="URL" required
BORDERCOLOR="color" specifies the color of the frame's borders. The color value is a hexadecimal red-green-blue triplet, or a color name. See Appendix B, "Color values."Navigator 3.0
FRAMEBORDER determines whether frame borders are displayed. Navigator 3.0
•YES causes an outline-3D border. •NO suppresses the 3D border, although the space the border would have occupied is is still present under control of the BORDER attribute of the FRAMESET tag.
When FRAMEBORDER appears in a FRAMESET tag, it sets a default FRAMEBORDER value for all frames in the frameset.
When FRAMEBORDER appears in the FRAME tag, it applies only to that particular frame, overriding any FRAMEBORDER established by an outer FRAMESET tag.
A border shared between frames is plain only if all adjacent frames have the FRAMEBORDER attribute set to NO.
When neither a FRAME nor a FRAMESET governing that FRAME has set FRAMEBORDER, the default setting is YES.
MARGINHEIGHT="pixMarHeight" specifies a margin in pixels between the top and bottom edges of the frame and the frame contents.
MARGINWIDTH="pixMarWidth" specifies a margin in pixels between the left and right edges of the frame and the frame contents.
FRAMESET (define a group of frames)
The FRAMESET tag defines a group of frames that appear in a single Netscape Navigator window. You define and specify the features of the group of frames by using the following tags nested within the FRAMESET tag:
•FRAME defines each individual frame. Each frame can be defined with unique features and characteristics using the FRAME tag's attributes. •NOFRAMES provides alternative content for the FRAMESET tag and is for browsers that cannot display frames.
The only place the FRAMESET tag is used is in a frame definition document. A frame definition document is an HTML document that contains the layout for each frame and frameset that make up a Navigator window. An HTML document that contains a FRAMESET tag cannot contain a BODY tag.
Syntax
...
Attributes:

ONLOAD="loadJScode"
ONUNLOAD="unloadJScode"
ROWS="RowHeightList" Either COLS or ROWS is required
BORDER="pixWidth"specifies the thickness of frame borders for all frames in a frameset. A setting of BORDER="0" causes all frames in the frameset to have no border between them. A setting of BORDER="3" causes a border of 3 pixels. If no BORDER tag is present, the default is 5 pixels. The BORDER tag can be used only on an outermost FRAMESET tag. Navigator 3.0
BORDERCOLOR="color" specifies the color of a frame's borders. The value of color is a hexadecimal red-green-blue triplet, or a color name. See Appendix B, "Color values."Navigator 3.0
COLS="ColumnWidthList" specifies a comma-separated list of values giving the width of each frame in the frameset. If one of the values is missing, the corresponding frame is sized to fit by the browser. The browser can approximate some values to make the total height of the rows equal to the height of the window or the total width of the columns equal to the width of the window. ColumnWidthList can be:
•Size of a frame in pixels. •Percentage size of each frame. •Relative size of each frame, using asterisk (*) to mean "as much space as possible."
FRAMEBORDER determines how frame borders are displayed.Navigator 3.0
•YES causes an outline-3D border. •NO causes a plain border.
When FRAMEBORDER appears in the FRAMESET tag, it sets a default FRAMEBORDER value for all frames in that frameset. When FRAMEBORDER appears in a FRAME tag, it applies only to that particular frame, overriding any FRAMEBORDER established by an outer FRAMESET tag. A border shared between frames is plain only if all adjacent frames have the FRAMEBORDER attribute set to NO. When neither a FRAME nor a FRAMESET governing that FRAME has set FRAMEBORDER, the default setting is YES.
ONBLUR="blurJScode" specifies JavaScript code to execute when the window containing the frameset loses focus. See the JavaScript Guide for information on event handlers.Navigator 3.0
ONFOCUS="focusJScode" specifies JavaScript code to execute when the window containing the frameset loses focus. See the JavaScript Guide for information on event handlers.Navigator 3.0
ONLOAD="loadJScode" specifies JavaScript code to execute when the frameset is loaded into the frame. See the JavaScript Guide for information on event handlers.
ONUNLOAD="unloadJScode" specifies JavaScript code to execute when the frameset is unloaded (exited). See the JavaScript Guide for information on event handlers.
ROWS="RowHeightList" specifies a comma-separated list of values giving the height of each frame in the frameset. If one of the values is missing, the corresponding frame is sized to fit by the browser. The browser can approximate some values to make the total height of the rows equal to the height of the window or the total width of the columns equal to the width of the window. RowHeightList can be:
•Size of a frame in pixels. •Percentage size of each frame. •Relative size of each frame, using asterisk (*) to mean "as much space as possible."
