What Does 'zoom' do in CSS?

Question

I found that some jQuery Plugin, in their css rule uses \'zoom\' descriptor, I even Look into w3c website and found that it is used to magnify but how can I actually impleme

Answer 1

zoom is a css3 spec for the @viewport descriptor, as described here

http://dev.w3.org/csswg/css-device-adapt/#zoom-desc

used to zoom the entire viewport ('screen'). it also happens to zoom individuals elements in a lot of browsers, but not all. css3 specifies transform:scale should be used to achieve such an effect:

http://www.w3.org/TR/css3-transforms/#transform-functions

but it works a little different than the 'element zoom' in those browsers that support it.
