Designer Guide

Of course, these are just general tips; some professional might prefer to
do it all directly in PhotoShop, then jump right into PHP, HTML and CSS.
Technical recommendations
In order to ensure that you can easily share your creation with others
(designer, integrators, client), we advise you to save them as a
PhotoShop file (RGB, 72 dpi, non-flattened).
You should work with the 980px width resolution in mind.
Layer arrangement
You can use several methods, depending on your preferences:
 A folder for every text layers, so that integrators can easily access
the design itself.
 A folder for each design blocks (New products, Best sales, etc.)
Colors
Do not use the CMYK color model, as it is only adapted to printing. Always
use the RVB color model.
Fonts
Do not use atypical fonts! Keep it readable at all times!
Standard text (title, sub-title, regular text) should be limited to the
followed fonts, in order to insure that all visitors can see the same thing:
 Arial
 Verdana
 Helvetica
 Georgia
 Tahoma
 Times News Roman
Keep the number of fonts to the bare minimum, for fear of making your
website confusing and unreadable.
Units
When designing for the Web, the basic unit of measurement is the pixel.
Do not measure in picas, points or centimeters.
