radio[pane] {
list-style-image: url("jar:resource:///chrome/classic.jar!
/skin/classic/browser/preferences/Options.png");
}
radio[pane="prefpane-appearance"] {
-moz-image-region: rect(0px, 32px, 32px, 0px);
}
radio[pane="prefpane-appearance"]:hover,
radio[pane="prefpane-appearance"][selected="true"] {
-moz-image-region: rect(32px, 32px, 64px, 0px);
}
Can anyone explain a syntax of this css, particularly what is pane.. I couldn't find such attribute for radio element in context of XUL. So I guess it's some custom attribute? If it is, then how it is evolving through the lines, first declaration, then several assignments? It has also selected, which means can have multiple custom attributes?
How can those attributes be used later?
