HTML

HTML

• Developed by Tim Berners-Lee in 1990, HTML is short for HyperText Markup Languageand is a language used to create electronic documents, especially pages on the World Wide Web that contain connections called hyperlinks to other pages. 
• Every web page you see on the Internet, including this one contains HTML code that helps format and show text and images in an easy to read format.
• The first DOC Type line describes what encoding the page uses. Next, the HTML tag begins letting the browser know that HTML code is being used until it is terminated at the end of the page. 
• Next, the head section contains header information about the page, which will almost always contain the title of the page and the meta tags. 
• Finally, the body section is all content that is viewable on the browser.

• HTML5 is the update made to HTML from HTML4.
• It uses the same basic rules as HTML4, but adds some new tags and attributes which allow for better semantics and for dynamic elements that are activated using JavaScript. 
• New elements include section, article, aside, header, hgroup, footer, nav, figure, figcaption, video, audio, track, embed (different usage), mark, progress, meter, time, ruby, rt, rp, bdi, wbr, canvas, command, details, datalist, keygen, and output. There are new input types for forms, which include tel, search, url, email, datetime, date, month, week, time, datetime-local, number, range, and color.

• A number of elements have been removed due to being presentational elements, accessibility issues, or lack of use. These should no longer be used: basefont, big, center, font, strike, tt, frame, frameset, noframes, acronym, applet, isindex, and dir.
