Most likely the rule is not specific enough (aka a different css rule is overriding it). Try doing rules like  (It could be something else, trying the !important will narrow it down). You can also use firebug to inspect which css rule takes precedence for a specific element (really helpful for debugging css)

Another thing to try is to use the css validator: http://jigsaw.w3.org/css-validator/ which will tell you if you made any syntax mistakes (and probably give a list of all css rules in affect on the webpage).
