How did it take me so long to discover this incredible app? Xyle Scope is invaluable for anyone who works with CSS and is one of these few, special gems that really deserve to be given the much-abused "must have" label.

When my page looks broken, I pray it's also broken on WebKit :) Then it's just a matter of a few clicks and voila -- unexpected paddings, collapsed margins, whacky rules cascade -- it's all there.

Completely brilliant application. Can't live without it - worth the cash!

This application saved my day some many times, one of my best secret tools.
Some times friends call me to ask me if I can help them understand a web site CSS structure, and Xyle does it for me.

Good work.

We all wait for new versions and features for editing...


This works better than the CSS plugins for FireFox. I've looked on the PC (Wiindows) side, they don't have anything like it.

It works a bit choppy at times, but for anyone that has ever had to skin / redesign someone elses code this app is pure solid gold.

This application is extremely useful. I just registered it because I've been using it repeatedly, day after day, when helping a friend redesign her site. This let me zero in on and identify the problems she was having in a matter of seconds, when otherwise I would have had to spend minutes, if not hours, poring over CSS to try and figure it out in my head.

Mac UI Power. I'd be surprised if this didn't at least get nominated for an Apple Design Award.

no app similar to this exist. Its totallly unique
