The property is read/write for all objects except the following, for which it is read-only: currentStyle. The property has a default value of scroll. The Cascading Style Sheets (CSS) attribute is not inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see about dynamic properties.

this property can be set with the other background properties by using the background composite property.
microsoft® internet explorer 3.0 supports the background-attachment attribute, but only when it's set by using the background attribute.
