Look, designers can stick to making the website look amazing in photoshop, but let the engineers actually tell you what's possible or not using simple, responsive practices. Don't expect pixel perfect, do expect lean websites built to last.

It is always fun to discuss with customers that expect pixel perfect designs, to the point that they actually measure them it all browsers specified on the contract.

Thankfully, I am not the one usually sitting in those meetings.

But what pixel perfect means in fact? That it looks as it was supposed to. If I'm a designer and design something which looks perfect, do I want a coder to alter this perfect look to something ugly?

Ideally pixel perfect is replaced with "looks perfect" and designer works closely with coder to achieve perfect look on various devices and resolutions. But I don't think coder should make assumptions how the coded design can differentiate from the original design (unless they have very good aesthetics feeling).

Well, on those meetings means that someone on the customer side had the wonderfull job of using an on screen pixel ruler and counted the exact number of pixels.

Pixel count not the same as on the PSD image, across all targeted browsers? No money, even if it is only 1 pixel.

As ridiculous as it sounds, I do know a few of such cases.
