A common approach to web dev is to start with a dumb page - just HTML
and then add CSS and JS. This is known as progressive enhancement.

Another approach which I've read about recently is called regressive
enhancement. Essentially, you start at the cutting edge, using the
functionality that you want (canvas for example), and then add in the
missing features.

As more of the browsers that support the newer features become the
popular ones, you end up with less code providing support for older
browsers. So, when every browser supports canvas, you don't need to
install any code to emulate the canvas. Modenizr and YepNope are the
tools I read about for this.
