you could have a container that in container.css you define
.Head { font-family:Verdana, Arial, Helvetica, sans-serif; font-size:13px; font-weight:bold; color:#BDBDBD;}
.Normal {font-family:Verdana, Arial, Helvetica, sans-serif; font-size: 11px; font-weight:Normal; color:#BDBDBD; padding:0; line-height:140%; letter-spacing:140%;}
/* Orange Text display */
#orange .Head { font-family:Verdana, Arial, Helvetica, sans-serif; font-size:13px; font-weight:bold; color:#F7941D;}
#orange .Normal { font-family:Verdana, Arial, Helvetica, sans-serif; font-size: 11px; font-weight:Normal; color:#BDBDBD; padding:0;}
then if you put a div around the whole lot of the container like <div id="orange"> then you will be using the orange class and if your container does not have it which means you will be using the regular .HEAD
