Why is this Popular

[cyrus]

Is there any extra features that is possessed by CSS3 when compared with CSS2. I want to know what made CSS3 more popular than its earlier release.

there are lot of changed in css3.... it's not an easy answer but here is some notes...

• Selectors
  Selectors in CSS 3 are going to be very interesting. They will allow the designer/developer to select on much more specific levels of the document. One of the nice things about this module is that many browsers are already starting to support the advanced CSS 3 selectors, so you can start trying them out now. For example, some new selectors are:
  • matching on attributes and attribute values, including partial matches
  • structural pseudo-classes, such as the nth-child
  • a target pseudo-class to style only elements that are targetted in the URL
  • a checked pseudo-class to style any element that is checked such as radio or checkbox elements
• Text Effects and Layout
  Making changes to the hyphenation, whitespace, and justification of text in documents.
• First-Letter and First-Line Pseudo-Classes
  CSS 3 should allow properties to affect kerning and alignment of drop-caps.
• Paged Media and Generated Content
  CSS 3 will now support more options in paged media, such as running headers and footers and page numbers. Plus there will be advanced properties for printing generated content including properties for footnotes and cross-references.
• Multi-Column Layout
  Right now, the multi-column layout working draft provides properties to allow designers to display their content in multiple columns with definitions like the column-gap, column-count, and column-width.
• Ruby
  CSS will now support the ability to add small annotations on top or next to words, most often used in Chines and Japanese. They are generally used to give the pronunciation or meaning of difficult ideograms.

I still work with CSS2 but after reading through that I might change.

Anyone else have experience with CSS3?
