Worse still are the expectations that static visuals set in the minds of clients, particularly when designers use them as a method to get sign-off for a design. I often wonder, is the fact that so many web pages are fixed-width and centered, a direct result of clients signing off fixed-width design visuals?
I would even go so far and say that when you demonstrate a design as a static image, you are reinforcing a mistaken notion that a web page will be a facsimile of a frozen image. And when you demonstrate a design or ask for sign-off on a frozen image, you immediately leave yourself open to the problems that often come when you later implement that design.
We all know that it is impossible today for a design to render exactly the same in every browser or device.
You need only look at the different ways that Gecko and Webkit and Opera anti-alias text. The browser landscape is more diverse today than it ever has been before.
I know that many designers and developers understand that it’s neither practical, economical or desirable to attempt cross-browser pixel perfection, but what about the clients and managers that we work for? They still often subscribe to the outdated notion that you should strive for pixel perfection.
