Among justsayhi.com's collection of funny widgets, right next to the "Can you survive a zombie apocalypse" quiz, there are two quizzes for web designers. They are called "How many HTML elements can you name in 5 minutes" and "Home many CSS properties can you name in 7 minutes." The premise is simple: once you open the page the clock starts ticking and you need to write HTML tags or CSS properties in a text box. After the time is up, you get a summary of what you got right and what you missed.

The quizzes are a nice way to refresh your skills and test yourself, but the interesting thing is whether that kind of quizzes will make their way into job interviews. Simple, yet enlightening.

Currently, HTML 4.0 consists of 91 elements, up from 22 in the first specification. The count of CSS properties is higher, 122.
