HTML contains a main plugin wrapper with a class "world-map-container". Inside there is a button to minimize the map inside a fullscreen view. Map iframe from Google is inside #world-map.

If you would like to edit the color, font, or style of any elements in one of these columns, you would do the following:

#world-map-container a {color: #someColor;}

If you find that your new style is not overriding, it is most likely because of a specificity problem. Scroll down in your CSS file and make sure that there isn't a similar style that has more weight.

I.E.

#wrap #world-map-container a {color: #someColor;}

So, to ensure that your new styles are applied, make sure that they carry enough "weight" and that there isn't a style lower in the CSS file that is being applied after yours.
