HTML<\/p>\n

Web is a collection of documents that all link together, and bear a strong similarity to the printed documents around us. Web pages are written in HTML (Hypertext Markup Language) or XHTML (eXtensible Hypertext Markup Language). Both are document-layout and hyperlink-specification language. They define how to display the contents of the document, including text, images, and other support media. The language also tells how to make hypertext links, which connect document with other documents.<\/p>\n

Elements, Tags and Attributes<\/strong><\/p>\n

HTML is an embedded language, the language’s directions or tags are inserted into the HTML document that browser loads for viewing. The web browser uses the information inside the HTML tags to decide how to display or otherwise treat the subsequent contents of a HTML document.<\/p>\n

Similar to a word processor like MS-Word in which styles are applied to the text; in a HTML document markups or tags are applied to stylize text as bold or italicize. Specific tags are applied on the text for specific styling.<\/p>\n

HTML documents are composed of a tree of HTML elements. Each element can have attributes specified. Elements can also have content, including other elements and text. HTML elements represent semantics, or meaning. For example, the title element represents the title of the document. In the HTML syntax, most elements are written with a start tag and an end tag, with the content in between like<\/p>\n

<p>In the HTML syntax, most elements are written …<\/p><\/p>\n

However, not all of these elements require the end tag, or even the start tag, to be present like the br element.<\/p>\n

HTML element<\/strong> \u2013 It represents structure or semantics and generally consists of a start tag, content, and an end tag for example, following is a bold element<\/p>\n

<b> This is in bold or more dark.<\/b><\/p>\n

HTML tags<\/strong> \u2013 They are used to mark the start and end of an HTML element.<\/p>\n

Start tag<\/strong> has opening angle bracket (<) followed by element name, zero or more space separated attribute\/value pairs, and a closing angle bracket (>).<\/p>\n

A start tag with no attributes:\u00a0\u00a0 <p><\/p>\n

A start tag with an attribute\u00a0\u00a0\u00a0\u00a0\u00a0 <p class=”info”><\/p>\n

End tag<\/strong> has opening angle bracket followed by forward slash, the element name, and a closing angle bracket\u00a0<\/p><\/p>\n

Empty tag<\/strong> There are also some elements that are empty, meaning that they only consist of a single tag and do not have any content and look like opening tags\u00a0<br><\/p>\n

In XHTML. empty elements must have an end tag or the start tag must end with \u2018\/>\u2019 so it is used as\u00a0<br \/><\/p>\n

Difference<\/strong> – A tag consists of a left- and right-angle bracket and letters and numbers between those brackets, but an element is the opening and closing tags plus anything between the two tags.<\/p>\n

HTML Attributes<\/strong> \u2013 It defines property for an element, consists of an name and value pair appearing within the element\u2019s start tag. Multiple name and value pairs are space separated.<\/p>\n

All are illustrated in the figure<\/p>\n

Head and body tags<\/strong><\/p>\n

A web page is contained between the opening <html> and closing <\/html> tags.<\/p>\n

<html> element – <\/strong>This element contains the whole HTML document. HTML document should have one opening <html> tag and document should end with a closing <\/html> tag. It has <head> and <body> tags in it.<\/p>\n

<head> element – <\/strong>It is the head of the page, having information about the page but not the content of the page as it contain a title and a description of the page, or location for CSS and JavaScript files. The element has an opening <head> tag, the closing <\/head> tag, and everything in between.<\/p>\n

<body> element <\/strong>\u00a0– It is the body of the web page and has all the content seen on the web page. It consists of the opening <body> tag, closing <\/body> tag, and everything in between. Usually it appears after <head> element and the contents in it are also called as body content. It can have some paragraphs or complicated layouts having forms and tables for example<\/p>\n

<body><\/p>\n

<p>This is a paragraph tag.<\/p><\/p>\n

<\/body><\/p>\n

Nesting – <\/strong>An element containing other elements, must wholly contain that element. This is called as nesting elements correctly.<\/p>\n

HTML Editor<\/strong><\/p>\n

HTML editors are used help a HTML designer efficiently and effectively develop web pages in HTML or XHTML which are not only compliant to standards but also fulfill the user need. Some popular Notepad can also be used as an HTML editor.<\/p>\n

The whole web page with html, head and body tag is made by joining earlier sections as<\/p>\n

<html><\/p>\n

<head><\/p>\n

<title>Head tag example <\/title><\/p>\n

<meta name=”Keywords” content=” Head tag, example\u201d \/><\/p>\n

<meta name=”description” content=” Head tag example” \/><\/p>\n

<\/head><\/p>\n

<body><\/p>\n

<p>This is a paragraph tag.<\/p><\/p>\n

<\/body><\/p>\n

<\/html><\/p>\n
