 HTML Document Structure HTML pages consist of elements, which usually consist of a start tag and an end tag, usually with text content between them; we can put some properties in the start tag that change the behavior of the element or set it.

The basic divisions of elements are: Start tag: This contains the name of the element, enclosed in angle brackets, and the name may be followed by the properties that affect it. For example <p>, . End tag: This also contains the element name preceded by a slash before it to indicate the end of the element; note that forgetting the end tag can sometimes cause errors, so be careful and remember it. For example: <p/>. Content: This is located between the start and end tags, and most of the time represents the content of the element. Element: The start tag, the end tag, and the content

Day1

 HTML proposed and prototyped a system for CERN researchers to use and share documents. In 1989 he wrote a memo  proposing a hypertext system based on the Internet, and described the HTML language and wrote the server and browser software in the late 1990s. The first public description of HTML was a document called HTML Markup, first mentioned on the web by Berners-Lee in late 1991. It describes 18 of the first elements that make up the HTML. The relatively simple design of HTML except for the hyperlink tag, these were strongly influenced by SGML QUID, SGML was founded as a document in the CERN home office. Eleven of these elements still exist in HTML. Hypertext Markup Language (HTML) is a markup language that web browsers use to interpret and compose text, images, and other visual or audible material on web pages. The default properties of each HTML item are defined and described in the browser, and these properties can be changed or enhanced by the web page designer using ad...
