… Centricle’s show specific elements : when it prompted me for “Which elements?”, I entered: “*”, it prompted me for a color, I entered “red”. The result? Everything had a red box around it. I highly recommend this diagnosis method for when things get confusing with your CSS layout. [From: webgraphics]
I tried the favelet and it worked nicely in Safari (I didn’t try it with anything else). This is one for the toolbox. The favelets and CSS filters at Centricle are also something to know about.
