An HTML document starts and ends with <html> and >/html> tags. These tags tell the browser that the entire document is composed in HTML. Inside these two tags, the document is split into two sections:
- The <head>...</head> elements, which contain information about the document such as title of the document, author of the document etc. Information inside this tag does not display outside.
- The <body>...</body> elements, which contain the real content of the document that you see on your screen
HTML language is a markup language and we use many tags to markup text. In the above example you have seen <html>, <body> etc. are called HTML tags or HTML elements.
Every tag consists of a tag name, sometimes followed by an optional list of tag attributes , all placed between opening and closing brackets (< and >). The simplest tag is nothing more than a name appropriately enclosed in brackets, such as <head> and <i>. More complicated tags contain one or more attributes , which specify or modify the behaviour of the tag.According to the HTML standard, tag and attribute names are not case-sensitive. There's no difference in effect between <head>, <Head>, <HEAD>, or even <HeaD>; they are all equivalent. But with XHTML, case is important: all current standard tag and attribute names are in lowercase.
HTML is Forgiving?
A very good quality associated with all the browsers is that they would not give any error if you have not put any HTML tag or attribute properly. They will just ignore that tag or attribute and will apply only correct tags and attributes before displaying the result. We can not say, HTML is forgiving because this is just a markup language and required to
format documents.
