The correct syntax for url()-specified CSS cursors says that to use a url()-defined cursor, it must be one option in a list that ends with a cursor value listed in the CSS specification[1] (e.g., pointer, auto, wait, help, etc.). Examples of the proper syntax are: <style type="text/css"> p { cursor: url(http://www.example.com/testcursor.cur),auto; } </style> <span style="cursor:url(http://www.example.com/testcursor.cur),auto"></span> However, the syntax specified at the site is an IE-specific alternate which allows for the omission of the fallback cursor. This is against the spec, but unfortunately most instructions on specifying custom cursors omit the fallback value. Examples of the syntax which should be used (and which needs to be changed on the site in question) are: <style type="text/css"> p { cursor: url(http://www.example.com/testcursor.cur); } </style> <span style="cursor:url(http://www.example.com/testcursor.cur);"></span> Particularly now that code to support such CSS code has been checked into the tree and will be in Firefox 1.1, we need to get this site to update its instructions so that new pages will display properly in all browsers. Preferably, the person to make contact with the page's author should be familiar with the CSS specification as it deals with cursors so that we get the description of cursor syntax corrected properly. It's also worth pointing out at the same time that currently Mozilla doesn't support ANI cursors, though it does support CUR, static GIF, all the flavors of PNG that I could find, and BMP formats for custom cursors. 1. http://www.w3.org/TR/REC-CSS2/ui.html#cursor-props
