cloud4xL on "[HATCH THEME] Hiding Custom Added CSS??"

Hello all,

My question is for anyone who uses, or has used the Hatch theme by Galin Simeonov. I'm currently using ver. 0.2.6, and I was wondering if anybody knows if there's a way to hide the custom CSS you can add through the "Theme Settings" menu?

I've tried adding it straight into the theme's CSS file, but for some reason, no of the styles seem to work with the theme that way :\...

Any ideas?
