HTML element Wikipedia. An HTML element is an individual component of an HTML document or web page, once this has been parsed into the Document Object Model. HTML is composed of a tree of HTML nodes, such as text nodes. Each node can have HTML attributes specified. Nodes can also have content, including other nodes and text. Many HTML nodes represent semantics, or meaning.

So, when you click the button, it redirects to a page. I would like it to be as accessible as possible. Search. Google About Google Privacy Terms. For example, the title node represents the title of the document. ConceptseditDocument vs. DOMeditHTML documents are delivered as documents. These are then parsed, which turns them into the Document Object Model DOM internal representation, within the web browser. Presentation by the web browser, such as screen rendering or access by Java. Script, is then performed on this internal model, not the original document. Early HTML documents, and to a lesser extent today, were largely invalid HTML and riddled with syntax errors. The parsing process was also required to fix up these errors, as best it could. The resultant model was often not correct i. Thus, for example, an author might create a table of contents whose entries link to header elements H2, H3, etc., in the same document. Using the A element to create. HTML standard. A valid model was produced, no matter how bad the tag soup supplied had been. Only in the rarest cases would the parser abandon parsing altogether. Elements vs. tagseditElements and tags are terms that are widely confused. HTML documents contain tags, but do not contain the elements. The elements are only generated after the parsing step, from these tags. As is generally understood, the position of an element is indicated as spanning from a start tag, possibly including some child content, and is terminated by an end tag. This is the case for many, but not all, elements within an HTML document. Create terrific lightbox jQuery slideshows in second without a line of code. All browsers and devicesAs HTML is based on SGML,4 its parsing also depends on the use of a DTD, specifically an HTML DTD such as that for HTML 4. The DTD specifies which element types are possible i. Html Code Create Link' title='Html Code Create Link' />HTML and it also specifies the valid combinations in which they may appear in a document. It is part of general SGML behavior that where only one valid structure is possible per the DTD, it is not generally a requirement that the document explicitly states that structure. As a simple example, the lt p start tag indicating the start of a paragraph element should be closed by a lt p end tag, indicating the end of the element. Also the DTD states that paragraph elements cannot be nested. Html Code Create Link' title='Html Code Create Link' />The HTML document fragment lt p Para 1 lt p Para 2 lt p Para 3can thus be inferred to be equivalent to lt p Para 1 lt p lt p Para 2 lt p lt p Para 3If one paragraph element cannot contain another, any currently open paragraph must be closed before starting another. Because of this implied behavior, based on the combination of the DTD and the individual document, it is not possible to infer elements from the document tags alone, but only by also using an SGML or HTML aware parser, with knowledge of the DTD. SGML vs. XMLeditSGML is complex, which has limited its widespread adoption and understanding. XML was developed as a simpler alternative. XML is similar to SGML, that can also use the DTD mechanism to specify the supported elements and their permitted combinations as document structure. XML parsing is simpler. The relation from tags to elements is always that of parsing the actual tags included in the document, without the implied closures that are part of SGML. In Macros HTML can be formed as XML, either through XHTML or through HTML5, the parsing of document tags as DOM elements is simplified. How Do I Program An Rca Universal Remote Control on this page. Once the DOM of elements is obtained, behaviour beyond that point i. Part of this CSS presentation behavior is the notion of the box model. This is applied to those elements that CSS considers to be block elements, set through the CSS display block declaration. HTML also has a similar concept, although different, and the two are very frequently confused. HTML DTD that group elements as being either block level or inline. This is used to define their nesting behavior block level elements cannot be placed into an inline context. This behavior cannot be changed, it is fixed in the DTD. Block and inline elements have the appropriate and different CSS behaviors attached to them by default,7 including the relevance of the box model for particular element types. Note though that this CSS behavior can, and frequently is, changed from the default. Lists with lt ul lt li. However, it is quite common to set these with CSS to display as an inline list. OvervieweditParts of an HTML container element. In the HTML syntax, most elements are written with a start tag and an end tag, with the content in between. An HTML tag is composed of the name of the element, surrounded by angle brackets. An end tag also has a slash after the opening angle bracket, to distinguish it from the start tag. For example, a paragraph, which is represented by the p element, would be written aslt p In the HTML syntax, most elements are written. However, not all of these elements require the end tag, or even the start tag, to be present. Some elements, the so called void elements or empty elements, do not have an end tag. A typical example is the br element, which represents a significant line break, such as in a poem or an address. A void elements behavior is predefined, and it cannot contain any content or other elements. For example, an address would be written aslt p P. Shermanlt br 4. Wallaby Waylt br Sydneylt p When using an XHTMLDTD, it is required to open and close the element with a single tag. To specify that it is a void element, a is included at the end of the tag not to be confused with the at the beginning of a closing tag. P. Shermanlt br 4. Wallaby Waylt br Sydneylt p HTML attributes are specified inside the start tag. For example, the abbr element, which represents an abbreviation, expects a title attribute within its opening tag. This would be written aslt abbrtitleabbreviation abbr. There are multiple kinds of HTML elements void elements, raw text elements, and normal elements. Void elements only have a start tag, which contains any HTML attributes. They may not contain any children, such as text or other elements. Often they are place holders for elements which reference external files, such as the image lt img element. The attributes included in the element will then point to the external file in question. Another example of a void element is the lt link element, for which the syntax islt linkrelstylesheethreffancy. This lt link element points the browser at a style sheet to use when presenting the HTML document to the user. Note that in the HTML syntax, attributes dont have to be quoted if they are composed only of certain characters letters, digits, the hyphen minus and the full stop. When using the XML syntax XHTML, on the other hand, all attributes must be quoted, and a trailing slash is required before the last angle bracket lt linkrelstylesheethreffancy. Raw text elements are constructed with a start tag lt tag marking the beginning of an element, which may incorporate any number of HTML attributes some amount of text content, but no elements all tags, apart from the applicable end tag, will be interpreted as content an end tag, in which the element name is prefixed with a slash lt tag.
