HTML <!DOCTYPE> Tag
<!DOCTYPE>tag is used for specifying which language and version the document is using. This is referred to as the document type declaration (DTD).
With the introduction of HTML 5, the
<!DOCTYPE>tag is mostly useless, as HTML 5 does not require a reference to a DTD. Having said that, for legacy reasons, the HTML 5 specification recommends including the
<!DOCTYPE>header at the top of all HTML documents.
- Example Code:
<!DOCTYPE html> <html> <head> <title>Document Title</title> </head> <body> <p>Document Contents</p> </body> </html>
