Several new CSS3 properties, additional HTML5 elements and more example values

We have added several new CSS3 properties, as updated by W3. We have also added several example values to some of these properties, so that you can see what kind of different options are possible. Not only would this make it easier to code, it will be fun to do all kinds of stuff  just by changing some of the preset values!

We have also added some new HTML5 (as updated by W3C) tags as well, along with their new attributes!
