In a standard ZC stylesheet, many of the elements that SHARE a declaration are "nested" together, as this can save a lot of space.
So, it is not unusual to have to "split up" these nestings to give one particular class or id its own declaration.
eg:
Code:
#firstItem, #secondItem, #thirdItem {
border: 1px solid #cccccc;
}
In the above, ALL (#firstItem, #secondItem, #thirdItem) will have a solid border of 1px in color #cccccc .
Let's say you want #secondItem to NOT have a border...
Code:
#firstItem, #thirdItem {
border: 1px solid #cccccc;
}
#secondItem {
border: none;
}
