In this article, you will learn about the difference between HTML and HTML5.

HTML stands for HyperText Markup Language and HTML5 is the latest version of HTML Language. It is a cleaner markup and improved code for developers. HTML5 comes with a host of new elements and functional attributes.

In HTML file, DOCTYPE defines the HTML version. The browser also reads the DOCTYPE to identify the running HTML version.

The new elements and functional attributes of HTML5 are listed below:

  • A simpler way to DOCTYPE declaration: <!DOCTYPE html>
  • New semantic elements: <header>, <footer>, <main>, <section>, <article>, <figure>, <aside>, and <nav> etc.
  • New attributes of form elements: number, date, time, calendar and range, etc.
  • New form elements: <datalist> and <output>
  • New graphic elements: <svg> and <canvas>
  • New multimedia elements: <audio>, , <source>, <track>, and <video>

Key Differences

  • Audio and video were not part of older HTML version specifications and now, both are an integral part of HTML5 specifications.
  • Vector graphics are also an integral part of HTML5 such as SVG and canvas while vector graphics is possible in HTML only in conjunction with various technologies such as VML, Silver-light, Flash, etc.
  • In HTML, browser cache can be used as temporary storage. In the case of HTML5, application cache, web SQL database, and web storage is used.
  • HTML doesn’t allow JavaScript to run in a web browser, it runs in the same thread as browser interface whereas HTML5 allows JavaScript to run in the background and that is possible because of JS Web worker API in HTML5.
  • HTML works smoothly only with old browsers while most of the modern web browsers have started supporting HTML5 specifications. These browsers include Firefox, Mozilla, Chrome, Opera, Safari, etc.
