That is indeed how it works. The expected way to use transitions is  
"state based" where you can use class or pseudo-classes like :hover to  
animate the full transition from one state to another, including all  
properties. Additional CSS properties can give fine-grained control  
over which properties transition and how.

In addition, an element can have multiple transitions in effect at the  
same time (for example, if you add two classes, each of which set  
different properties, or if you poke individual properties directly  
through the CSSOM).
