Just what I needed

The site I am designing uses a theme that I have written, a child theme that I have written, and is modified by an essential plugin, creating a new post-type, that I had also written. I suddenly found that my new theme was not displaying the new post-type correctly. Now, I clearly need to go away and edit my plugin. But I knew the CSS that I needed to get it to work, yet didn’t want to just drop it into the child theme, because I need to re-use that child theme elsewhere as well. So, I thought, wouldn’t it be great if someone had made a plugin that would just allow these 2 little bits of CSS to be dropped in! And someone has! You! Your plugin has got me out of a tight corner, while I go away and reprogram my ‘Creation Cache’ plugin. Wonderful!
