How to Set Custom Cursor Images in CSS, Especially in Firefox?

Using Custom Cursor Images in CSS

You may occasionally want to use a custom cursor image, such as a magnifying glass, for a specific element on a webpage. While this can be easily achieved in many browsers, Firefox presents a unique challenge.

One common method for setting a custom cursor is through CSS. However, the code provided by the user, a.heroshot img {cursor:url(/img/magnify.cur), pointer;}, unfortunately does not work in Firefox.

The issue lies in the fact that Firefox on macOS does not support using URL-based cursor definitions. To resolve this, you can utilize the -moz-zoom-in keyword instead:

a.heroshot img {
  cursor: url(/img/magnify.cur), -moz-zoom-in, auto;
}

This updated CSS code will display the magnify.cur image on browsers that support it, the Firefox-specific zoom cursor on Firefox, or a system default cursor if neither is supported. The first cursor on the list that the browser recognizes will be applied.

It's important to note that you can find a list of cursor keywords supported by different browsers online to ensure compatibility across platforms.
