There is no single, integrated CSS4 specification,[52] because the specification has been split into many separate modules which level independently. Some units – cm (centimetre); in (inch); mm (millimetre); pc (pica); and pt (point) – are absolute, which means that the rendered dimension does not depend upon the structure of the page; others – em (em); ex (ex) and px (pixel) – are relative, which means that factors such as the font size of a parent element can affect the rendered measurement. { bidder: 'onemobile', params: { dcn: '8a9690ab01717182962182bb50ce0007', pos: '8a9694390178783c4ccf416436a60266' }}, }; { bidder: 'sovrn', params: { tagid: '346693' }}, Other browsers followed soon afterward, and many of them additionally implemented parts of CSS 2.

One example of a widely used pseudo-class is :hover, which identifies content only when the user "points to" the visible element, usually by holding the mouse cursor over it.
