problem with suffix for pages and modules

Hi! To adjust the individual elements used suffixes. But i have problem - they do not work. I read some articles on gavick.com, but still does not understand. For example, I would like to change the width of "readon-button" only in one articles http://consultant30.ru/index.php/seminary. I'm going to template manager - gk news 2 - advanced settings tab. And in field "custom css code" write:

Code: Select all

.MUSS readon-button {
width: 25%!important;
}

Then go to "features " tab and in field "Suffixes for pages" write:
ItemID/Option - 981 - id articles in menu
Suffix: MUSS
The idea is to work, but no. Something i do wrong.

1. You should use lower case:

Code: Select all

muss


2. There is an error in your css:

Code: Select all

.MUSS readon-button {
width: 25%!important;
}


should be:

Code: Select all

.MUSS .readon-button {
width: 25%!important;
}
