JavaFX style checkbox

I use this css-script which i include over setStyle:

checkBox.setStyle("" +
            ".check-box:selected > .box {\n" +
            "    /* background color for selected checkbox */\n" +
            "    -fx-background-color: lime;\n" +
            "}\n" +
            "\n" +
            ".check-box > .box {\n" +
            "    /* background color of unselected checkbox */\n" +
            "    -fx-background-color: red;\n" +
            "}\n" +
            "\n" +
            ".check-box:selected > .box > .mark,\n" +
            ".check-box:indeterminate  > .box > .mark {\n" +
            "    /* modify mark color */\n" +
            "    -fx-background-color: blue;\n" +
            "}");

But it doesn't work....

I use Java 9
