Check - HOW-To: Convert PSD to HTML/CSS - page 115

In this last step, called “ check ”, you will verify your
converted index.html that it matches the .psd design
and check for bugs in other browsers.
And, if you find any, you start to fix them.
Here's the list of the web browsers you're going to
check the converted design and see if it's okay:
• Chrome 19 (19.0 - used when coding);
• Internet Explorer 7 and 8;
• Opera 11 (11.64);
• Firefox 12 (12.0);
• Safari 5 (5.1.7).
In Internet Explorer 7 and 8, it's important to have
an accessible design rather than a pixel-perfect one.
Having a pixel-perfect design in all browsers would
be nice, but the cost of supporting Internet Explorer 7
or 8 is simply higher and requires more time.
