I would like to share some tools which help us to use CSS3 easily here.
1. CSS3 Features Preview
CSS3.info shows you the examples of CSS3 most popuplar and ready to use features, and explain how it work.
2. Web Font
Limited fonts we could use in web is always a big pain in ass though we have Multiple-Approach to get beautiful fonts in web by Font-Replacement Solutions, such as SIFR, FLIR, Cufón, etc. CSS3’s @font-face is a great way to use pretty fonts wherever we want. With a little help from the tools below, the job will be easiler and possible.
