Question

I have been trying to build my own gradient mixin in SASS based on the background mixin from Compass.

There is a line in the source that says the following:

$add-pie-bg: prefixed(-pie, $backgrounds) or $mult-bgs;

I have looked everywhere but I cant find reference to what the prefixed function does.

Can anybody shed a bit of light on this one?

Answer 1

Read the documentation.

prefixed($prefix, $arg, ...)

Returns true if any of the arguments require the given prefix.
