You can't change the data-id or it will mess up the colors for every user on the wiki. And you can't use darkred for the color either, it has to be whichever color you want the tab colors to be, which is probably blue in this case. As for the part you want to change, I'm not sure why that doesn't work, but maybe changing the other part will fix that.
