Nu Studio

Apologies, I did try to correct this yesterday, but this forum would not let me edit or repost to the thread for some reason.

Anyway, just add this code to the bottom of the style.css. The code above is the whole CSS file.

[Moderator note – it is NOT recommended to modify any theme files, especially in a default theme ]
