What is the difference between an acronym and abbr tags?


In layman language, an acronym is a word formed by taking letters of each word in a phrase to form an abbreviation. Acronyms are a subset of abbreviations i.e. abbreviation is a shortened form of a word.

The <acronym> tag isn’t supported in HTML5 and is deprecated now. Do not use. To add abbreviation in HTML, use the <abbr> tag. Both abbreviation and acronym are the shortened versions and are represented as a series of letters. Some of the examples include, "Mr.", "IST", "MRI", “NASA”, “ISRO” etc. 

Example

You can try to run the following code to add abbreviation in HTML.
