In summary, the HTML 4 specification primarily reined in all the various HTML implementations into a single clearly written specification based on SGML. XHTML 1.0, ported this specification, as is, to the new XML-defined specification. Next, XHTML 1.1 takes advantage of the extensible nature of XML and modularizes the whole specification. XHTML 2.0 was intended to be the first step in adding new features to the specification in a standards-body-based approach. HTML documents are required to start with a Document Type Declaration (informally, a "doctype").
HTML Tags
As of version 4.0, HTML defines a set of 252 character entity references and a set of 1,114,050 numeric character references, both of which allow individual characters to be written via simple markup, rather than literally. A literal character and its markup counterpart are considered equivalent and are rendered identically. Learn about the different global attributes along with attributes specific to particular HTML elements. With our free online editor, you can edit the HTML code and view the result in your browser. Web pages can be created and modified by using professional HTML editors. Use these HTML editor features to practice and to maximize your coding efficiency.
Colors
Its purpose is to embed an image in the HTML page in the place it appears. HTML (HyperText Markup Language) is the code that is used to structure a web page and its content. For example, content could be structured within a set of paragraphs, a list of bulleted points, or using images and data tables.
Frameset versus transitional
However, the SGML concept of generalized markup is based on elements (nested annotated ranges with attributes) rather than merely print effects, with separate structure and markup. The World Wide Web is composed primarily of HTML documents transmitted from web servers to web browsers using the Hypertext Transfer Protocol (HTTP). However, HTTP is used to serve images, sound, and other content, in addition to HTML.
For documents that are XHTML 1.0 and have been made compatible in this way, the W3C permits them to be served either as HTML (with a text/html MIME type), or as XHTML (with an application/xhtml+xml or application/xml MIME type). When delivered as XHTML, browsers should use an XML parser, which adheres strictly to the XML specifications for parsing the document's contents. It is the standard language used to create and design web pages on the internet.

The code editor lets you write and practice different types of computer languages. It includes HTML/CSS/JavaScript, but you can use it for other languages too, such as PHP, Python, Node.js, etc. Those are the main changes necessary to translate a document from XHTML 1.0 to HTML 4.01. To translate from HTML to XHTML would also require the addition of any omitted opening or closing tags. Whether coding in HTML or XHTML it may just be best to always include the optional tags within an HTML document rather than remembering which tags can be omitted. ] HTML specifications lies in the distinction between the SGML-based specification and the XML-based specification.
A Simple HTML Document
Click CTRL + U in an HTML page, or right-click on the page and select "View Page Source". This will open a new tab containing the HTML source code of the page. It must only appear once, at the top of the page (before any HTML tags).
Semantic HTML
The visual editor works like a regular text composer, just use the commands above the text area to adjust the content and in the meantime you'll notice the source editor changing with it. If you're familiar with HTML code composing then you can adjust the code on the right. Before you start composing the content for a live website I advise you to experiment with the features populating the work area with a demo text clicking the Quick Tour menu option. The editor is compatible with every major web browser without installing any program, extension or plugin.

Table of Content
To allow the web browser to know how to handle each document it receives, other information is transmitted along with the document. This meta data usually includes the MIME type (e.g., text/html or application/xhtml+xml) and the character encoding (see Character encoding in HTML). HyperText Markup Language, or HTML, is the standard markup language for describing the structure of documents displayed on the web. HTML consists of a series of elements and attributes which are used to mark up all the components of a document to structure it in a meaningful way.
It contains the essential building-block elements (i.e. doctype declaration, HTML, head, title, and body elements) upon which all web pages are created. This language is used to annotate (make notes for the computer) text so that a machine can understand it and manipulate text accordingly. The language uses tags to define what manipulation has to be done on the text. This module will introduce the first two of these and introduce fundamental concepts and syntax you need to know to understand HTML.
If omitted, the browser applies the effect of the opening tag until the end of the page. By learning the basics of HTML, you can start creating your own web pages and bring your ideas to life online. Hypertext defines the link between the web pages and Markup language defines the text document within the tag. There are some WYSIWYG editors (What You See Is What You Get), in which the user lays out everything as it is to appear in the HTML document using a graphical user interface (GUI), often similar to word processors.
HTML stands for HyperText Markup Language and it is used to create webpages. It uses HTML tags and attributes to describe the structure and formatting of a web page. Most graphical email clients allow the use of a subset of HTML (often ill-defined) to provide formatting and semantic markup not available with plain text. This may include typographic information like colored headings, emphasized and quoted text, inline images and diagrams.
This declaration references the DTD for the "strict" version of HTML 4.01. SGML-based validators read the DTD in order to properly parse the document and to perform validation. In modern browsers, a valid doctype activates standards mode as opposed to quirks mode. As this list demonstrates, the loose versions of the specification are maintained for legacy support. However, contrary to popular misconceptions, the move to XHTML does not imply a removal of this legacy support.
Rather the X in XML stands for extensible and the W3C is modularizing the entire specification and opens it up to independent extensions. The primary achievement in the move from XHTML 1.0 to XHTML 1.1 is the modularization of the entire specification. The strict version of HTML is deployed in XHTML 1.1 through a set of modular extensions to the base XHTML 1.1 specification. Likewise, someone looking for the loose (transitional) or frameset specifications will find similar extended XHTML 1.1 support (much of it is contained in the legacy or frame modules). Modularization also allows for separate features to develop on their own timetable.
The operation of this free online tool with built-in HTML cleaner is very intuitive and it's working in your web browser without installing any additional program. Compose your text using the WYSIWYG editor on the left and adjust formatting of the source code on the right. To convert Microsoft Word, PDF or any other rich-text documents to HTML, simply paste it in the visual editor. Perform bulk operations on the HTML code by clicking the Clean button after adjusting the settings.
Name the file "index.htm" and set the encoding to UTF-8 (which is the preferred encoding for HTML files). Then under "Open and Save", check the box that says "Display HTML files as HTML code instead of formatted text". Every web publisher might need a good gibberish text generator for his editor to fill the page until the live content takes its place. You can also use the code editor in W3School Spaces to build frontend or full-stack websites from scratch.
