HTML Tutorial
Hyper Text Markup Language (HTML)
is the main markup language for creating web pages and other information that can be displayed in a web browser like Internet Explorer/ Firefox / Chrome etc. In the name HyperText Markup Language, HyperText refers to the fact that HTML allows you to create links that allow visitors to move from one page to another quickly and easily. A Markup Language allows you to annotate text and these annotations provide additional meaning to the contents of a document.HTML code is made up of characters that live inside angled brackets(< and >) and these are called HTML elements. HTML elements are made up of two tags: an opening tag and a closing tag(The closing tag has an extra forward slash in it). Each HTML element tells the browser something about the information that sits between its opening and closing tags. HTML tags most commonly come in pairs like <h1> (opening tag) and </h1> (closing tag) , although some tags, known as empty elements, are unpaired, for example <br/>. Attributes provide additional information about the contents of an element. They appear on the opening tag of the element and are made up of two parts: a name and a value separated by an equals sign. Attribute name indicates what kind of extra information you are supplying about the element’s content. It should be written in lowercase. The value is the information or setting for the attribute. It should be placed in double quotes. Different attributes can have different values.
HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts written in languages such as JavaScript which affect the behavior of HTML web pages.
What is the Purpose of a Web Browser:
The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page.Web browsers can also refer to Cascading Style Sheets (CSS) to define the appearance and layout of text and other material. The W3C, maintainer of both the HTML and the CSS standards, encourages the use of CSS over explicit presentational HTML markup.
HTML 5
HTML5 is the cooperation between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG). WHATWG was working with web forms and applications, and W3C was working with XHTML 2.0. In 2006, they decided to cooperate and create a new version of HTML.Advantages of HTML 5
New features should be based on HTML, CSS, DOM, and JavaScriptReduce the need for external plugins (like Flash)
Better error handling
More markup to replace scripting
HTML5 should be device independent
The development process should be visible to the public
