HTML is Hyper Text Markup Language used to create web pages. HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets like <html>, which normally comes in pairs like <p> and </p>. The first tag in a pair is the start tag or opening tag, and the second tag is known as the end tag or closing tag. The end tag is written with a slash before the tag name. Some tags also come without pair like <img>. HTML is a set of codes that is inserted into a plain text file to format the content. HTML tags are also used to add lists, tables, music, images and other elements to a web page. We as humans are always interested in upgrading and making technology better and better to suit and serve our needs, similarly HTML has undergone many versions and the latest version is HTML5.
Geolocation in HTML5 is best known for use in mobile devices. Geolocation is the art of finding out where you are in the world at present and if you wish share that information among your trusted people. There are number of ways to figure out where you are like which cell tower your phone is making use of during talking, your IP address, your wireless network connection or dedicated GPS hardware that calculates longitude and latitude from information through satellites placed in the sky.
HTML5 is good and we should shift to HTML5 as it is easy to understand for us and more easy to understand for google spiders and thus gives a huge leap in search engine optimization ranking. HTML5 websites are easier to index by any user agent and the websites may appear in higher position in any search engine.
