css
Solution
The value `1.231` is the value for the `line-height` property (see the `font` shorthand property for further information). The number without a unit refers to the element’s font size.
Problem
I found this css ``` body { font: 13px/1.231 arial,helvetica,clean,sans-serif; *font-size: small; *font: x-small; } ``` What is 1.231?
