Change color of single custom menu widget item

Replies: 0

Hello,
I am new to wordpress and would like to have support on this issue:

I have made a child theme for the parent theme Make and would like to customise the color of the first two custom menu items on the sidebar (About, Contact), but I can’t seem to do it in my child theme css file.

Here is the link to my site: margheritatamraz.com

Many Thanks
