I saw some post before to customize the color/font size for single value (range map), but it seems it doesn't work well in Splunk6. It seems there is a file called single-value.css controls the color code/font size of the single values and the labels, some codes like:
but when I tried to defined my own color code and font size in a customized css stylesheet or in application.css, it didn't take effect and cannot override the default settings. Any idea how to achieve that? For example, I want to change the under label color to #000000 and change the color for severe range to #ff0000.
