Probably the ultimate development of graphic presentations was the Dynamic page implementation of the University of Southern California BBS ( USCBBS ) by Susan Biddlecomb, which predated the implementation of the HTML Dynamic web page.

If the character encoding for a web page is chosen appropriately then HTML character references are usually only required for a markup delimiting characters mentioned above, and for a few special characters ( or not at all if a native Unicode encoding like UTF-8 is used ).

It employs HTML metadata tags embedded within web page documents to specify the type of content contained in the document.

To render a document such as an HTML page, most web browsers use an internal model similar to the DOM.

When an HTML page is rendered in a browser, the browser downloads the HTML into local memory and parses it, using the DOM to construct the internal data structures employed to display the page in the browser window.

The DOM is also the way in which JavaScript sees the state of the browser and the current HTML page.

DHTML allows scripting languages to change variables in a web page's definition language, which in turn affects the look and function of otherwise " static " HTML page content, after the page has been fully loaded and during the viewing process.

HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets ( like < code >< nowiki >< html ></ nowiki ></ code >), within the web page content.

The browser does not display the HTML tags, but uses the tags to interpret the content of the page.

Default characteristics for every item of HTML markup are defined in the browser, and these characteristics can be altered or enhanced by the web page designer's additional use of CSS.

The markup text < nowiki >'< title > Hello HTML </ title >'</ nowiki > defines the browser page title.

The response from the server was always an HTML page.

The applet can be displayed on the web page by making use of the deprecated HTML element, or the recommended element.

Meta elements are the HTML or XHTML element used to provide structured metadata about a Web page.

In one form, elements can specify HTTP headers which should be sent before the actual content when the HTML page is served from Web server to client.

In the general form, a element specifies and associated attributes describing aspects of the HTML page.

HTML abstract and first page image

With HTML and a tool to render it ( perhaps web browser software, perhaps another user agent ), one can create and present a page that lists items for sale.

∠, the angle symbol in Unicode is List of XML and HTML character entity references | U + 2220

Character entity references are also sometimes referred to as named entities, or HTML entities for HTML.

Hexadecimal character references are case-insensitive in HTML.

However, for backward compatibility with early HTML authors and browsers that ignored this restriction, raw characters and numeric character references in the 80 – 9F range are interpreted by some browsers as representing the characters mapped to bytes 80 – 9F in the Windows-1252 encoding.

The character entity references,, and are predefined in HTML and SGML, because,, and are already used to delimit markup.

For a list of all named HTML character entity references, see List of XML and HTML character entity references ( approximately 250 entries ).

Unnecessary use of HTML character references may significantly reduce HTML readability.

Unlike traditional HTML with its large range of character entity references, in XML there are only five predefined character entity references.

HTML markup consists of several key components, including elements ( and their attributes ), character-based data types, character references and entity references.

The HTML 4 character entity references for the Greek capital and small letter lambda are "&# 923 ;" and "&# 955 ;" respectively.

Reference-free reflects the HTML requirement that entity references are for special characters and do not contain markup.

Character entities can be included in an HTML document via the use of entity references, which take the form < var > EntityName </ var >, where < var > EntityName </ var > is the name of the entity.

For the full list, see: List of XML and HTML character entity references.

When linking to PDF documents from an HTML page the " attribute name " can be replaced with syntax that references a page number or another element of the PDF, for example, page = – "# page = 386 ".

* In HTML character entity references and can be used.

Netscape Navigator supported a feature called " JavaScript entities " or " script macros " by which script code could be included in HTML attribute values, using a syntax similar to that of character entity references.

HTML pages may embed parameters that are passed to the applet.

HTML pages may embed parameters that are passed to the applet.

The applet viewer operates on HTML documents, but all it looks for is embedded applet tags ; any other HTML code in the document is ignored.

Each time the applet viewer encounters an applet tag in an HTML document, it launches a separate applet viewer window containing the respective applet.

Because the applet viewer ignores all HTML codes except applet tags, it does not even attempt to display any other information contained in the HTML document.

One of the most noticeable differences between HTML and XHTML is the rule that all tags must be closed: empty HTML tags such as < code >< nowiki ></ nowiki ></ code > must either be closed with a regular end-tag, or replaced by a special form: < code >< nowiki > < nowiki >/></ nowiki ></ code > ( the space before the '< code >< nowiki >/</ nowiki ></ code >' on the end tag is optional, but frequently used because it enables some pre-XML Web browsers, and SGML parsers, to accept the tag ).

The meta element has two uses: either to emulate the use of the HTTP response header, or to embed additional metadata within the HTML document.

In HTML, there is a standard set of 252 named character entities for characters-some common, some obscure-that are either not found in certain character encodings or are markup sensitive in some contexts ( for example angle brackets and quotation marks ).

For HTML pages serialized as XML, then declaration options is to either rely on the encoding default ( which for XML documents is UTF-8 ), or to use an XML encoding declaration.

The text portion consists of either an HTML internal frame tag which causes buggy e-mail clients to automatically execute the worm, or a few lines of text that attempt to induce the recipient to execute the worm by opening the attachment ( sometimes by claiming that the attachment is a patch from Microsoft ; sometimes by claiming that the attachment is an antidote for the Klez worm ).

Once the worm is executed, either automatically by the buggy HTML engine or manually by a user, it searches for addresses to send itself to.

Text HTML editors commonly include either built-in functions or integration with external tools for such tasks as source and version control, link-checking, code checking and validation, code cleanup and formatting, spell-checking, uploading by FTP or WebDAV, and structuring as a project.

In web page design, and generally for all markup languages such as SGML, HTML, and XML, a well-formed element is one that is either

The learning content itself is either included in the zip file if it is HTML or other media that can run on its own, or else is referenced as a URL from within the manifest.

The information is then either handed over to a Java Servlet which interacts with a database and produces an HTML-formatted response, or it is given to a JavaServer Pages ( JSP ) document that intermingles HTML and Java code to achieve the same result.

In addition to the name itself, users can opt to forward their web traffic using HTML frames and their email traffic, with a maximum of 250 addresses per user log in, or use full DNS, either via their own or third-party servers, or by using Dot TK's servers.

Distinct from a mobile browser is a web-based emulator, which uses a " Virtual Handset " to display WAP pages on a computer screen, implemented either in Java or as an HTML transcoder.

For example, a text encoded page may contain HTML and XML encoding, combined in a plain text file format, using either EBCDIC or ASCII character encoding, on a UDF digitally formatted disk.

Buttons specified in HTML may be rendered by web browsers in different ways, typically either using the native button appearance of the underlying OS, or by using a button definition from within the browser.

Sites that use CSS with either XHTML or HTML are easier to tweak so that they appear extremely similar in different browsers ( Internet Explorer, Mozilla Firefox, Opera, Safari, etc.

Because the code points 128 through 159 are not used for displayable glyphs in either ISO-8859-1 and Unicode, character references in that range ( such as ) are illegal in HTML and ambiguous, though they are commonly used by many web sites.

A font family and other presentation attributes of a font may be applied in HTML code in either cascading style sheets ( CSS ) or the deprecated HTML element.

The output from a HAT can be either a compiled Help file in a format such as WinHelp (*. HLP ) or Microsoft Compiled HTML Help (*. CHM ), or noncompiled file formats such as Adobe PDF, XML, HTML or JavaHelp.

It can generate documentation in HTML, either with frames or without.

Sites are generally created using either HTML or Adobe Flash.

It provided on-the-fly conversion from XML to any format, such as HTML, WAP or text using either W3C standard techniques, or flexible custom code.
