Here are some entries you'll understand even if you aren't a designer or developer:
- Bouncing loader creates an animation without using any image files.
- Disable selection makes it impossible for the user to select text. (Evil!)
- System font stack lets a developer pick which fonts to display if others aren't available.
- Sibling fade grays out other text when the user hovers over something, like a menu bar.
