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 auto. The Cascading Style Sheets (CSS) attribute is 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.

remarks

the property handles a comma-separated list of cursor values. if the user agent does not understand or cannot find the first cursor specified, it looks at the next cursor in the comma-separated list and continues until it finds a usable cursor. if the user agent does not understand any of the cursors that are listed, the cursor does not change.
