How to separate the styles in 2 different elements in Enfold theme

I manually changed the navigation menu text color to white in style sheet. In my database page the text has become white too. I think the same css has used on both elements. How do I separate the style from both of them, change the database color to black and navigation Menu to white? I have little knowledge of how to make modifications in style sheet. This is beyond my expertise. Please help me.
