Font Style?

[Shadowkith]

is there any way to change the font style?

[Xrystal]

In what way do you mean style ?

You can adjust which font types are used by editing your localization file in the main subfolder. Use -- in front of the fonts you do not want to use and remove them from in front of ones you do want.

You can adjust the size of the font from many of the elements by editing the appropriate layout file.

[Petrah]

In /Interface/Addons/nUI/Main find your localization file.

--	nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\ABF.ttf";
--	nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\Accidental Presidency.ttf";
--	nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\Adventure.ttf";
--	nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\Bazooka.ttf";
	nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\Emblem.ttf";
--	nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\Enigma__2.ttf";
--      nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\Tw_Cen_MT_Bold.ttf";
--	nUI_L["font1"] = "Interface\\AddOns\\nUI\\Layouts\\Default\\Fonts\\VeraSe.ttf";

Or, you can cheat like I do and use nUI Config GUI

Or get the nUI config add on that you can find in the download section, works fine.
