Does anything under the CSS attributes for the side bar works? If not, check the CSS coding above the side bar to see for an unclosed '{' or any other possible mistakes.

I adlready check through and cannot find any mistake and it can run well in google chroome as well. Got friend suggested me to use if else in css is it possible?
