menu aside for tablet and phone

Hi
Is not the same the menu aside displayed on desktop, the tablet / cellphone.

Aside from the desktop menu will change color.

Where do I change the color tone of the menu that is posted on tablets and cellphones?

Hi

I can see You are using dropdown based menu. This type of menu is using html select element and the style of this element depends from the browser You are using. Unfortunately there is no way overrride the style which browser offers.
