Skin:MonoBook/en

MonoBook is a skin. It was the previous default skin for Wikimedia Foundation websites since MediaWiki 1.3 (2004), as the replacement for the old Standard skin.

Later, it adopted support for responsive web design for narrow, mobile phone displays, which also is designed with progressive enhancement in mind to maximize compatibility.
