UI Checker JavaScript / CSS tool
I have a task (for instance): create an HTML&CSS according to the given Jpg file. Basically, what i want, is a simple JavaScript 开发者_运维问答lib (or whatever else it might be) which will allow me to see the transparent gif of the original file (50% opacity) and my actual page, so that i could fit all my classes pixel-to-pixel according to Jpeg.
Does it exist?
This is a good extension, for Firefox:
