Need a "cross-platform" solution that allows to create pages that look nice and are rendered correctly on both desktops and mobiles (not only on "full-size" devices like iPads but as well on the mobile phones with 4" screens and medium screen resolutions).
"Custom" design means not only images (*.jpg, *.png, *.psd etc.) but also "hollow" (i.e. without any functionality) *.html pages (also known as a "layout") that are properly rendered on all supposed devices (desktop and mobile)
Person applying for this job MUST have CSS/HTML skills- NOTE I do not need illustrator, the illustrations have already been done.
