Minor adjustment on CSS

I have attached 2 files for you to have a look and correct the problem as we have 3 commands on CSS: Conteudo1, Conteudo2 and Conteudo3. The problem is when it is read by the robot Lynx, the order is wrong, showing: Conteudo3, Conteudo2 and Conteudo1 instead, even if on the screen it apears with the correct order. I need that the order becames Conteudo1, Conteudo2 and Conteudo3, on browsers and robots. Many Thanks!
