A program that checks css files for duplicate declarations of styles on the same element, Id or class. Can be used when adding external css libraries to a web project.
Examples of duplicates:
.sky{color: blue;}
.sky{color: orange;}
.sky{position: fixed;}
It will also mark weak duplicates (controlled by an option) such as
.sky{color: blue;}
.venus .sky{color: red;}
.mars > .sky {color: purple;}
#jupiter .sky{position: absolute}
It ignores @ rules for now (until a reason for going through the stress of including them is found)
@media, @font-face, etc
It also ignores the value of the filter attribute like so
.flint-michigan-water{filter: No support for filter prop;}
