Minifying nested CSS is broken

[PoseidonEnergy]

✅ This CSS minifies correctly:

var css = """
.someClass > * {
    width:calc(50% - (10px / 2));
}
""";
var minified = NUglify.Uglify.Css(css).Code;
Console.WriteLine(minified);

Output: .someClass>*{width:calc(50% - (10px/2))} ✅

---

❌ The same CSS does not minify correctly if nesting is involved:

var css = """
:nth-child(n){
    .someClass > * {
        width:calc(50% - (10px / 2));
    }
}
""";
var minified = NUglify.Uglify.Css(css).Code;
Console.WriteLine(minified);

Output: :nth-child(n){.someClass> * {width:calc(50% -(10px / 2));}} ❌

In the output, notice the white space around the asterisk was not removed, and the calc() statement was broken (the space after the minus sign should not have been removed).

CSS nesting is relatively new so it's understandable that it's not supported yet. To learn more about CSS nesting click here: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_nesting/Using_CSS_nesting
