In case you didn’t already know, viewing generated source is quite simple in FIrefox via an addon appropriately called Web Developer. In Safari 3, the closest thing is to right click and select “Inspect Element” from the contextual menu.
I am still stunned at how far IE has fallen behind in feature set for both users and developers in its seventh iteration of the software (having zero development effort since it drove Netscape into ground). But I am still thankful for conditional comments the IE team has decided to support. At least it’s made life with IE using CSS a much more straight forward task.
