try1-cr4: The role for footer is missing What does main add (there are no various main sections to group here)
try1-cr10: There are widths for layout in the linear layout
try1-cr11: The widths in layout (criterium 10) cause a horizontal scrollbar in linear
try1-cr16: This subject needs some more time from you, and why not keep the links in the bottom of the page in the menu?
try1-cr17: Make sure that the user has the title of the page in sight, even in the smallest vriwport, the image is not wrong, but in my opinion the title would be better
try1-cr18: Why a background in linear for this site? And why not have 2 different (sized) background images for the 2- and 3 cols layout?
