XF 2.1 Changing navigation icons

[Rettep]

Simple question? How do I change theses icons in the navigation bar?

 

[JoyFreak]

[data-nav-id="newPosts"]:before {
.m-faBase();
content: "\f02e";
}

the ID can be found in the public navigation in admin cp.

Where do I put the code?

It seems you are not using the default style, it will be easier to ask to style author.
As @JoyFreak said you can set icons by adding the code in your extra.less template...
