Practice is key to mastering coding, and the best way to put your HTML knowledge into practice is by getting practical with code. After completing this tutorial, you’ll have a basic understanding of HTML and be ready for the next stage of web development, CSS. An important type of web agent that does crawl and read web pages automatically, without prior knowledge of what it might find, is the web crawler or search-engine spider. Discover how the very useful details and summary elements work, and where to use them. Right-click on an element (or a blank area), and choose "Inspect" to see what elements are made up of (you will see both the HTML and the CSS). You can also edit the HTML or CSS on-the-fly in the Elements or Styles panel that opens.
HTML links are defined with the tag:
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.
Appearance of elements
In browsers, the doctype helps to define the rendering mode—particularly whether to use quirks mode. Attributes contain extra information about the element that you don't want to appear in the actual content. Here, class is the attribute name and editor-note is the attribute value. The class attribute allows you to give the element a non-unique identifier that can be used to target it (and any other elements with the same class value) with style information and other things.

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.

This indicates further (nested) elements, as children of the parent element. Another important component is the HTML document type declaration, which triggers standards mode rendering. The best real-time online HTML editor with dynamic instant live visual preview, inline WYSIWYG editor and source cleaning features. Includes a HTML viewer, editor, compressor, beautifier and easy formatter.
HTML Tags
By understanding and using HTML tags effectively, you can create well-structured and informative webpages. Before starting this module, you don't need any previous HTML knowledge, but you should have at least basic familiarity with using computers and using the web passively (i.e., just looking at it and consuming content). You should have a basic work environment set up (as detailed in Installing basic software), and understand how to create and manage files (as detailed in Dealing with files). Both are parts of our Getting started with the web complete beginner's module.

In such circumstances, some authors conflate the two names as (X)HTML or X(HTML). Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for its appearance. The declaration represents the document type, and helps browsers to display web pages correctly. This contains two attributes, but there is no closing tag and no inner content.
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.
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.
Many such clients include both a GUI editor for composing HTML e-mail messages and a rendering engine for displaying them. The original purpose of the doctype was to enable the parsing and validation of HTML documents by SGML tools based on the Document Type Definition (DTD). The DTD to which the DOCTYPE refers contains a machine-readable grammar specifying the permitted and prohibited content for a document conforming to such a DTD. Browsers, on the other hand, do not implement HTML as an application of SGML and as consequence do not read the DTD. Tags may also enclose further tag markup between the start and end, including a mixture of tags and text.
Other elements are empty, with the tag and attributes defining their function. A markup language is used to define the text document within the tag to define the structure of web pages. By carefully following the W3C's compatibility guidelines, a user agent should be able to interpret the document equally as HTML or XHTML.
