// It is recommended that you use Sass's @extend directive to apply the behavior
// to your PIE elements. To assist you, Compass provides this variable.

// The default approach to using PIE.
// Can be one of:
//
// * relative (default)
// * z-index
// * none

// The location of your PIE behavior file
// This should be root-relative to your web server
// relative assets don't work. It is recommended that
// you set this yourself.

// When using the z-index approach, the
// first ancestor of the PIE element at
// or before the container's opaque background
// should have a z-index set as well to ensure
// propert z-index stacking.
//
// The `$position` argument must be some non-static
// value (absolute, relative, etc.)

// PIE elements must have this behavior attached to them.
// IE is broken -- it doesn't think of behavior urls as
// relative to the stylesheet. It considers them relative
// to the webpage. As a result, you cannot reliably use
// compass's relative_assets with PIE.
//
// * `$approach` - one of: relative, z-index, or none
// * `$z-index` - when using the z-index approach, this
// is the z-index that is applied.
