sorry, here the image.
You can see the green arrow that is the standard text.
I would like to reduce the font weight of other menu voices (red arrow).
As I wrote in my first post here, I already add some css (please read the previous message). And it works for other CSS stuff but not for font attributes. Probably the code you can see in my previous message works can work only on padding, margin and something else, but not on font. Is there a way to change font weight?

Thanks.
