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 elements and other nodes, such as text nodes. Elements can also have content, including other elements and text.
For example, the 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 element, which represents a significant line break, such as in a poem or an address.A void element's behaviour is predefined, and it cannot contain any content or other elements.For example, an address would be written as When using an XHTML DTD, 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).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. it did not represent what a careless coder had originally intended), but it would at least be valid, according to the 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.
