Dear Art Director...

Dear Art Director, I believe you are confused. To prove my point, please answer a simple multiple-choice question below.

On the web, people run:

1. Photoshop
2. Web browsers

Hint: the right answer is (b). It’s naive to expect a web page to render with pixel-perfect precision in every browser. It’s impossible and impractical. Your insistence to the contrary is wasting my time.

Yes! Forwarding this on now...

Right on!! I actually detest those PS designers who believes their nice picture will transcend automatically towards exactly looking webpages. They think it's a piece of cake to code in html and css.

Lazy frontend programmers talking...

But if you work with good frontend programmers it IS possible to have a pixel perfect page in the most common webbrowsers.

Shane: Yes, it is possible... If you require your visitors to run their browsers full-screen at a particular screen resolution. Good designer realize it about the users, not their design....

A good webdesigner should know how to deal with it and have a minimum background of XHTML and Javascrit coding and CSS. Browsers are not that bad these days and tabless design came up to help a lot.
cheers

as a designer, stop the mocking as a coder stop the mocking allready. i really dont see the hassle in coding a good design in css / html as a coder. And i really do not see the problem in using a photoshop mockup to prove a scetch. Either people are crappy designers or crappy coders. Get along do your part of the job and communicate with your fellow coder / designer. *Thumbs up*
