| <DIR> | Directory List | This element encloses a list of brief, unordered items, such as might occur in a menu or DIRectory. The individual items are indicated by the <LI> element. Use of this element is not encouraged, as it is not part of the HTML 4 stript specification and provides little extra benefit over the<UL> element. | |
| <DIV> | Division | This element indicates a block of document content, which should be treated as a logical unit. | |
| <DL> | Definition List | This element encloses a list of terms and definition pairs. A common use for this element is to implement a glossary. | |

| <FRAME> | Window Region | This element defines a nameable window region, known as a frame, that can independently display its own content. | |
| <FRAMESET> | Frameset Definition | This element is used to define the organization of a set of independent window regions known as frames , as defined by the <FRAME> element. This element replaces the <BODY> element in framing documents. | |
| H | <H1> Through <H6> | Headings | These tags implement six levels of document headings; <H1> is the most prominent, and <H6> is the least prominent. |
| <HEAD> | Document Head | This element indicates the document head that contains descriptive information aout the HTML document as well as other supplementary information such as style rules or scripts. | |
| <HR> | Horizontal Rule | This element is used to insert a horizontal rule to visually separate document sections. Rules are usually rendered as a raised or etched line. | |

| I | <I> | Italic | This element indicates that the enclosed text should be displayed in an italic typeface. |
| <IFRAME> | Floating Frame | This element indicates a floating frame, an independently controllable content region that can be embedded in a page. | |
| <ILAYER> | Inflow Layer | This Netscape-specific element allows the definition of overlapping content layers that can be positioned, hidden or shown, rendered transparent or opaque, reordered front to back, and nested. An inflow layer is a layer with a relative position that appears where it would naturally occur in the document, in contrast to a general layer, which may be positioned absolutely regardless of its location in a document. The functionality of layers is available using CSS positioning, and page developers are advised not to use this element. | |
| <IMG> | Image Map Area | This element indicates a media object to include in an HTML document. Usually, the object is a graphic image, but some implementations support movies and animations. | |
| <INPUT> | Input Form Control | This element specifies an input control for a form. The type of input is set by the TYPE attribute and may be a variety of different types, including single-line text field, multiline text field, password style, check box, radio button, or push button. | |
| <INS> | Inserted Text | This element is used to indicate that text has been added to the document . | |
| <ISINDEX> | Index Prompt | This element indicates that a document has an associated searchable keyword index. When a browser encounters this element, it inserts a query entry field at that point in the document. The viewer can enter query terms to perform a search. This element is depreciated under the strict HTML 4 specification and should not be used. | |
| K | <KBD> | Keyboard Input | This element logically indicates text as keyboard input. A browser generally renders text enclosed by this element in a monospaced font. |
| L | <LABEL> | Form Control Label | This HTML 4 element is used to relate descriptions to form controls. |
| <LAYER> | Content Layers | This Netscape-specific element allows the definition of overlapping content layers that can be exactly positioned, hidden or shown, rendered transparent or opaque, reordered front to back, and nested. The functionality of layers is available using CSS positioning facilities; page developers are advised not to use the <LAYER> element. | |
| <LEGEND> | Field Legend | This HTML 4 element is used to assign a caption to a set of form field as defined by the <FIELDSET> element. | |
| <LI> | List Item | This elemet is used to indicate a list item as contained in an ordered list (<OL>), unordered list (<UL>), or older list styles like <DIR> and <MENU>. | |
| <LINK> | Link to External Files or Set Relationship | This empty element specifies relationships between the current document and other documetns. Possible uses for this element include defining a relational framework for navigation and linking the document to a style sheet. | |
| <LISTING> | Code Listing | This depreciated element from HTML 2 is used to indicate a code listing; it is no longer part of the HTML standard. Text tends to be rendered in a smaller size within this element. Otherwise, the <PRF> element shold be used instead of <LISTING> to indicate preformatted text. | |
| M | <MAP> | Client-Side Image Map | This element is used to implement client-side image maps. The element is used to define a map to associate locations on an image with a destination URL. Each hot region or hyperlink mapping is defined by an enclosed <AREA> element. A map is bound to a particular image through the use of the USEMAP attribute in the <IMG> element, which is set to the name of the map. |
| <MARQUEE> | Marquee Display | This proprietary element specifies a scrolling, sliding, or bouncing text marquee. This is primarily a Microsoft-specific element, though a few other browsers, notably WebTV, support it as well. | |
| <MENU> | Menu List | This element is used to indicate a short list of items that might occur in a menu of choices. Like the ordered and unordered lists, the individual items in the list are indicated by the <LI> element. Most browsers render the <MENU> element exactly the same as the unordered list, so there is little reason to use it. Under the HTML 4 strict specification, <MENU> is no longer supported. | |
| <META> | Meta-Information | This element specifies general information about a document, which can be used in document indexing. It also allows a document to define fields in the HTTP response header when it is sent from the server. A common use of this element is for clint-pull page loading, which allows a document automatically to load another document after a specified delay. | |
| <MULTICOL> | Multiple Column Text | This Netscape-specific element renders the enclosed content in multiple columns. This element should not be used in favor of a table, which is a more standard way to render multiple columns of text across browsers. It is likely that style sheets will provide for multicolumn rendering in the future. | |
| N | <NOBR> | No Breaks | This proprietary element renders enclosed text without line breaks. Break points for where text may wrap can be inserted using the <WBR> element. |
| <NOEMBED> | No Embedded Media Support | This Netscape-specific element is used to indicate alternative content to display on browsers that cannot support an embedded media object. It should occur in conjunction with the <EMBED> element. | |
| <NOFRAMES> | No Frame Support Content | This element is used to indicate alternative content to display on browsers that do not support frames. | |
| <NOSCRIPT> | No Script Support Content | This element is used to enclose content that should be rendered on browsers that do not support scripting or that have scripting turned off. | |
| O | <OBJECT> | Embedded Object | This element specifies an arbitrary object to be included into an HTML document. Initially, this element was used to insert ActiveX controls, but according to the HTML 4 specification, an object may be any media object, document, applet, ActtiveX control, or even image. |
| <OL> | Ordered List | This element is used to define an ordered or numbered list of items. The numbering style comes in many forms, including letters, Roman numerals, and regular numerals. The individual items within the list are specified by<LI> elements included with the <OL> ekement. | |
| <OPTGROUP> | Option Grouping | This element specifies a grouping of items in a selection list defined by <OPTION> elements so that the menu choices may be presented in a hierarchical menu or similar alternative fashion to improve access via nonvisual browsers. | |
| <OPTION> | Option in Selection List | This element specifies an item in a selection list defined by the <SELECT> element. | |
| P | <P> | Paragraph | This element is used to define a paragraph of text. Browsers typically insert a blank line before and after a paragraph of text. |
| <PARAM> | Object Parameter | This element specifies a parameter to pass to an embedded object using the <OBJECT> or<APPLET> element. This element should occur only within the scope of one of these elements. | |
| <PLAINTEXT> | Plain Text | This depreciated elemet from the HTML 2 specification renders the enclosed text as plain text and forces the browser to ignore any enclosed HTML. Typically, information affected by the <PLAINTEXT> element is rendered in monospaced font. This element is no longer part of the HTML standard. | |
| <PRE> | Preformatted Text | This element is used to indicate that the enclosed text is preformatted, meaning that spaces, returns, tabs, and other formatting characters are preserved. Browsers will, however, acknowledge most HTML elements that are found with the <PRE> element. Preformatted text will generally be rendered by the browsers in a monospaced font. | |
| Q | <Q> | Quote | This elemetn indicates that the enclosed text is a short inline quotation. |
| S | <S> | Strikethrough | This element renders the enclosed text with a line drawn through it. |
| <SAMP> | Sample Text | This elemetn is used to indicate sample text. Enclosed text is generally rendered in a monospaced font. | |
| <SCRIPT> | Scripting | This element encloses statements in a scripting language for client-side processing. Scripting statements can either be included inline or loaded from an external file and may be commented out to avoid execution by non-scripting-aware browsers. | |
| <SELECT> | Selection List | This element defines a selection list within a form. Depending on the form of the selection list, the control allows the user to select one or more list options. | |
| <SMALL> | Small Text | This element renders the enclosed text one font size smaller than a document's base font size unless it is already set to the smallest size. | |
| <SPACER> | Extra Space | This proprietary element specifies an invisible region for pushing content around a page. | |
| <SPAN> | Text Span | This element is used to group inline text, typically so scripting or style rules can be applied to the content. As it has no preset or rendering meaning, this is the most useful inline element for associating style and script with content. | |
| <STRIKE> | Strikeout Text | This element is used to indicate strikethrough text, namely, text with a line drawn through it. The <S> element provides shorthand notation for this element. | |
| <STRONG> | Strong Emphasis | This element indicates strongly emphasized text. It is usually rendered in a bold typeface, but is a logical element rather than a physical one. | |
| <STYLE> | Style Information | This element is used to surround style sheet rules for a document. This element should be found only in the <HEAD> of a document. Style rules within a document's <BODY> element should be set with the style attribute for a particular element. | |
| <SUB> | Subscript | This element renders its content as subscripted text. | |
| <SUP> | Superscript | This element renders its content as supersclipted text. | |
| T | <TABLE> | Table | This element is used to define a tabele. Tables are used to organize data as well as to provide structure for laying out pages. |
| <TBODY> | Table Body | This element is used to group the rows within the body of a table so that common alignment and style defaults can be set easily for numerous cells. | |
| <TD> | Table Data | This element specifies a date cell in a table. The element should occur within a table row as defined by the <TR> element. | |
| <TEXTAREA> | Multiline Text Input | This element specifies a multiline text input field contained within a form. | |
| <TFOOT> | Table Footer | This element is used to group the rows within the footer of a table so that common alignment and style defaults can be set easily for numerous cells. This element may be particularly useful when setting a common footer for tables that are dynamically generated. | |
| <TH> | Table Header | This element specifies a header cell in a table. The element should occur within a table row as defined by a <TR> element. The main difference between this element and <TD> is that browsers may render table headers slightly differently. | |
| <THEAD> | Table Header | This element is used to group the rows within the header of a table so that common alignment and style defaults can be set easily for numerous cells. This element may be particularly useful when setting a common head for tables that are dynamically generated. | |
| <TITLE> | Document Title | This element encloses the title of an HTML document. It must occur within a document's <HEAD> element and must be present in all valid documents. Meaningful titles are very important since they are used for bookmarking a page and may be used by search endines attempting to index the document. | |
| <TR> | Table Row | This element specifies a row in a table. The individual sells of the row are defined by the <TH> and <TD> elements. | |
| <TT> | Teletype Text | This element is used to indicate that text should be rendered in a monospaced font similar to teletype text. | |
| U | <U> | Underline | This element is used to indicate that the enclosed text should be displayed underlined. |
| <UL> | Unordered List | This element is used to indicate an unordered list, namely, a collection of items that do not have a numerical ordering. The individual items in the list are defined by the <LI> element, which is the only allowed element within <UL>. | |
| V | <VAR> | Variable | This element is used to indicate a variable. Variables are identifiers that occur in a programming language or a mathematical expression. The element is logical, though enclosed text is often rendered in italics. |
| W | <WBR> | Word Break | This nonstandard element is used to indicate a place where a line break can occur if necessary. This element is used in conjunction with the <NOBR> element, which is used to keep text from wrapping. When used this way, <WBR> can be thought of as a soft line break in comparison to the <BR> element. This element is common to both Netscape and Microsoft implementations, though it is not part of any HTML standard. |
| X | <XMP> | Example | This depreciated element indicates that the enclosed text is an example. Exsample text is generally rendered in a monospaced font, and the spaces, tabs, and returns are preserved, as with the <PRE>element. As the <XMP> element is no longer standard, the <PRE> or <SAMP> elements should be used instead. |
