Pixel perfect layout bugfixing doesn't even feel like development, it only proves that some people got their priorities terribly wrong if they worry about a 2 pixel margin anywhere. And I do say this as a front end dev who does respect a respect a good design. But still, pixel pushing sucks!

I mean, I understand next to nothing in front end, design, art, and whatever. But As far as I know and have been told that those pixels do be having an effect statistically, and with so many people learning which things psychologically makes our monkey brains go: "Ooooh, pretty buttons, monkey now want to buy banana with buttons" I think they have their priorities pretty straight in that regard.

@SoldierOfCode the problem usually is in understanding what needs to be perfect.

Pixel perfect is often used yo describe the wrong type of perfection, one that is hard or impossible to achieve.

Or that misses the mark altogether by using absolute positioning instead of responsive design.

2 pixels is nothing in the same scope as 2 inches is nothing when it comes to sheer cliffs.

But I don't disagree when it comes to controlling product owners and armchair UXperts

No pixel left behind. One pixel misalignment can change a layout from feeling smooth to looking like something is wrong. Humans are surprisingly good at subconsciously finding slightly misaligned stuff.

Also, measuring or specifying in pixels is already a crime since a very large portion of devices and screens have different pixel densities and/or OS level scalings.

@Oktokolo has a point there. No need to be pixel perfect to the complete mock-up, but things need to be correctly aligned to one another.

No absolute perfection, but relative perfection.

Yes it sucks, but you would be surprised how tuned in your brain is to things being aligned down to the pixel.

An elegant looking product, without you realising it, will probably be pixel perfect and some dickhead like us had to sit and sweat over making it exactly like the designer wanted it.

Just embrace it, it's all good.
