/* Keyword value */
cursor: pointer;
cursor: auto;
/* URL, with a keyword fallback */
cursor: url(hand.cur), pointer;
/* URL and coordinates, with a keyword fallback */
cursor: url(cursor1.png) 4 12, auto;
cursor: url(cursor2.png) 2 2, pointer;
/* Global values */
cursor: inherit;
cursor: initial;
cursor: unset;
The cursor
property is specified as zero or more <url>
values, separated by commas, followed by a single mandatory keyword value. Each <url>
should point to an image file. The browser will try to load the first image specified, falling back to the next if it can't, and falling back to the keyword value if no images could be loaded (or if none were specified).
Each <url>
may be optionally followed by a pair of space-separated numbers, which represent <x><y>
coordinates. These will set the cursor's hotspot, relative to the top-left corner of the image.
For example, this specifies two images using <url>
values, providing <x><y>
coordinates for the second one, and falling back to the progress
keyword value if neither image can be loaded:
cursor: url(one.svg), url(two.svg) 5 5, progress;
Values
<url>
- A
url(…)
or a comma separated listurl(…), url(…), …
, pointing to an image file. More than one<url>()
may be provided as fallbacks, in case some cursor image types are not supported. A non-URL fallback (one or more of the keyword values) must be at the end of the fallback list. See Using URL values for the cursor property for more details. <x>
<y>
- Optional x- and y-coordinates. Two unitless nonnegative numbers less than 32.
- Keyword values

In some environments, an equivalent bidirectional resize cursor is shown. For example,n-resize
ands-resize

.e-resize
s-resize
w-resize

nw-resize
se-resize

nesw-resize
nwse-resize

Usage notes
Although the specification does not define any size limitations for cursor
, individual user agents may choose to do so. Cursor changes using images which are outside the size range supported by the browser will generally just be ignored.
Check the Browser compatibility table for any notes on cursor size limits.
