Проблема вот в чем:
решил проверить цсску на валидность (хттп://jigsaw.w3.org) со следующими настройками:
Warnings : All
Profile : CSS 2.1
Medium : All
валидатор выдает следующие предупреждения:
1) Same colors for color and background-color in two contexts #h3_usl and #popular a
2) You have no background-color set (or background-color is set to transparent) but you have set a color. Make sure that cascading of colors keeps the text reasonably legible.
3) You have some absolute and relative lengths in margin. This is not a robust style sheet.
4) You have no color set (or color is set to transparent) but you have set a background-color. Make sure that cascading of colors keeps the text reasonably legible.
5) Redefinition of display
6) You have no background-color set (or background-color is set to transparent) but you have set a color. Make sure that cascading of colors keeps the text reasonably legible.
7) Same colors for background-color and color
