DOM inspector tutorial
12th November 2002
An Introduction to the DOM Inspector (via Scott Andrew). The DOM inspector is a powerful but little-known tool that comes packaged with Mozilla and can be used to interactively browse through the DOM of both Mozilla interface components and any web page. The article mainly discusses using the inspector to investigate Mozilla internals, but as a web developer I frequently use it to analyse pages and see how they work. It is also great for tweaking other people’s sites in my browser (see my post covering Jeffrey Zeldman’s redesign for an example of this).
