The author has marked this style as obsolete.
Google (rather annoyingly) changed Google IG, by adding an expand-item button next to each RSS feed. While it's an okay feature, I didn't need it (I just use the RSS modules for quickly seeing new items, don't need to read descriptions and such), and more annoyingly : For some reason there is a white border around the table that has the items - I use a module which changes the background colour (bgColor), and the white-border around all modules look horrible.
This userstyle removes the [+] Buttons next to RSS items, and the white border around all modules. I also removed the bottom copyright notice and links.
Remove the last "section" (From div#footer, to the second last } ) if you want them back
