Question: Any CSS masters who know of a way to make a dotted 0? I had the idea of having a white strike through combined with a white forward slash and back slash as [described here](https://stackoverflow.com/questions/9685483/google-chrome-diagonal-css-line-through), but perhaps there's a better way.

Answer: 
Use a font with a dotted zero. You can use `@font-face` to include a font that you can guarantee will have a dotted zero.
You can use a custom font, or if it's good enough would the U+25CC DOTTED CIRCLE character `◌` work for you?
