Understanding CSS code

I want to use safire for my skin, but when I copy and paste the css code nothing happens. I am using Mr.Tech. Here is my current css for userChrome.css

@import url("chrome://global/skin/subskin/rounded.css");

@import url("chrome://global/skin/subskin/favbooktool.css");

@import url("chrome://global/skin/subskin/dropmarker.css");

@import url("chrome://global/skin/subskin/graybackground.css");

@import url("chrome://global/skin/subskin/classicgo.css"); @import url("chrome://global/skin/subskin/gosunken.css");

@import url("chrome://global/skin/subskin/systemmenus.css");

@import url("chrome://global/skin/subskin/highbooktool.css");

@import url("chrome://global/skin/subskin/nozebras.css");

@import url("chrome://global/skin/subskin/sunkenaqua.css");

@namespace url(";http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */scrollbarbutton[sbattr=scrollbar-up-top]{

display: none !important;

}

can't you just install the theme? do you have the JAR file?

I used the jar, but it isn't as refined as the picture. It has some rough edges.
