Before moving to the difference between both of these broader terms first it is important to define the mark up language as abbreviation for HTML is Hyper Text Mark-up Language where mark-up language is used to define the text document within tag which defines the structure of web pages.So HTML is the combination of Hypertext and Mark-up language.As already understood that HTML 5 is the advance version of HTML so on the basis of additional features in HTML 5 there are notable differences.
Following are the important differences between HTML and HTML 5
| Sr. No. | Key | HTML | HTML 5 |
|---|---|---|---|
| 1 | AV support | As HTML is the initial version of this language so did not have support for audio and video without the use of flash player. | On other hand HTML 5 supports audio and video controls with the use of "<audio>" and "<video>" tags. |
| 2 | Storage | HTML uses browser cookies and session for storage of data which is transferred from server to client side. | On other hand HTML 5 uses SQL databases and application's own cache to store application data at client end i.e it become more scalable for storing data than HTML. |
| 3 | JavaScript | HTML does not support JavaScript execution with its code execution as it treat JavaScript as server side language and does not support its code. | On other hand HTML 5 introduced with JS Web worker API which made JavaScript code execution possible in its backgroud along with the code execution of HTML. |
| 4 | Shapes | HTML does not support for the drawing of trigonometric shapes through its code at browser side. | On other hand HTML5 allows to draw shapes like circle, rectangle, triangle etc. |
| 5 | Browser Compatibility | HTML has better compatibility as compare to HTML 5 as it is supported with new browsers as well as with all old browsers. | On other hand HTML 5 is supported by all new browser like Firefox, Mozilla, Chrome, Safari, etc only and has limitation to be supported by older browsers. |
