In our website-house analogy, plumbing and electricity would both be handled by JavaScript—this is a language that deals with interactions and events.

However, JavaScript adds an additional layer of headaches complexity onto building a website, which I wouldn’t advise until you’re very comfortable with HTML and CSS.

Removing JavaScript creates an interesting creative constraint—you can make plenty of cool things without it!

Here are some examples:

• net-art.org: An amazing archive of lots of sites—many with just HTML and CSS used in inventive ways
• Cameron’s World
• Superbad.com
• Scrollbar Composition
• Simon Rogers’ rotating helix portfolio
• Old Boys Network
• Olia Lialina’s work, My Boyfriend Came Back from the War
• Not sure if this is strictly JavaScript-free but it’s a nice example of the blurred area between book design and website design.
