What is the abbreviation for language in which electronic document on web must be created?

There isn't a single, universal abbreviation for the language in which an electronic document on the web must be created.

Here's why:

* Multiple Languages: Websites can be built using various programming languages (HTML, CSS, JavaScript, Python, etc.). There isn't a single "required" language.

* Focus on Content: The language of the document itself (e.g., English, Spanish, French) is important for accessibility and search engine optimization, but it's a separate concept from the language the website is coded in.

What You Might Be Looking For:

* HTML: The core language for structuring web pages. It's the foundation for all web documents.

* "lang" attribute: Within HTML, you use the "lang" attribute to specify the natural language of the document's content (e.g., `` for English).

* Content Management Systems (CMS): These platforms (like WordPress, Drupal, Joomla) often use specific programming languages behind the scenes, but you interact with them through an interface that often doesn't require coding expertise.

To Summarize: While there's no single abbreviation for the "language" of web documents, understanding HTML and the "lang" attribute are crucial for creating accessible and well-structured websites.
