io preferisco dare un'occhiata alle specifiche W3C, il link e' questo:

e riguardo alla proprieta' cursor riporto qui sotto il tutto.


18.1 Cursors: the 'cursor' property

'cursor'
Value: [ [<uri> ,]* [ auto | crosshair | default | pointer | move | e-resize | ne-resize | nw-resize | n-resize | se-resize | sw-resize | s-resize | w-resize| text | wait | help ] ] | inherit
Initial: auto
Applies to: all elements
Inherited: yes
Percentages: N/A
Media: visual, interactive

This property specifies the type of cursor to be displayed for the pointing device. Values have the following meanings:

auto
The UA determines the cursor to display based on the current context.

crosshair
A simple crosshair (e.g., short line segments resembling a "+" sign).

default
The platform-dependent default cursor. Often rendered as an arrow.

pointer
The cursor is a pointer that indicates a link.

move
Indicates something is to be moved.

e-resize, ne-resize, nw-resize, n-resize, se-resize, sw-resize, s-resize, w-resize
Indicate that some edge is to be moved. For example, the 'se-resize' cursor is used when the movement starts from the south-east corner of the box.

text
Indicates text that may be selected. Often rendered as an I-bar.

wait
Indicates that the program is busy and the user should wait. Often rendered as a watch or hourglass.

help
Help is available for the object under the cursor. Often rendered as a question mark or a balloon.

<uri>
The user agent retrieves the cursor from the resource designated by the URI. If the user agent cannot handle the first cursor of a list of cursors, it should attempt to handle the second, etc. If the user agent cannot handle any user-defined cursor, it must use the generic cursor at the end of the list.

Example(s):

P { cursor : url("mything.cur"), url("second.csr"), text; }
