Why Aren't My External Images Working as CSS Custom Cursors?

External Images in CSS Custom Cursors: Limitations and Solutions

Manipulating cursors through CSS offers a unique touch to user interfaces. Customizing cursors with external images extends this customization further. However, the inability of an example to incorporate an external image as a cursor raises questions.

The provided CSS code fails to execute due to image size restrictions. Browsers like Firefox enforce a dimension limit of 128x128 pixels for custom cursors. The specified image exceeds this restriction.

Additionally, the CSS property requires an additional parameter. The following code incorporates the necessary adjustments:

.test {
  background: gray;
  width: 200px;
  height: 200px;
  cursor: url(http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif), auto;
}

The modification includes the addition of "auto" to the cursor property. This fallback cursor ensures that when an external image is unavailable, a default cursor is displayed.

In summary, using external images for CSS custom cursors requires adherence to size limits and the inclusion of "auto" in the cursor property to avoid display issues.
