How does the cursor property change the shape of the cursor? (Detailed explanation with pictures and text)

The content of this article is to introduce the method of changing the cursor shape with the cursor attribute, so that everyone can understand most of the commonly used cursor shapes that can be set by the cursor attribute. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

First let's take a look at how the cursor attribute changes the cursor shape.

css3 The basic syntax of the cursor attribute:

cursor: [ [ <uri> [<x> <y>]?,]* [ auto | default | none | context-menu | help | pointer | progress | wait | cell | crosshair | text | vertical-text | alias | copy | move | no-drop | not-allowed | e-resize | n-resize | ne-resize | nw-resize | s-resize | se-resize | sw-resize | w-resize | ew-resize | ns-resize | nesw-resize | nwse-resize | col-resize | row-resize | all-scroll | zoom-in | zoom-out | grab | grabbing ] ];

Note:

1. The cursor attribute applies to all elements;

2. The cursor attribute Only works on devices with a pointing device (such as a mouse); it has no effect on touch devices.

3. Not all browsers support all attribute values ​​of the cursor attribute, and all attribute values ​​may not display the same effect in all browsers and operating systems.

Let's take a look at what kind of cursor shape can be set by these attribute values ​​​​of the cursor attribute.

Image cursor (custom cursor)

:

One or Multiple comma-separated url()s to point to images to be used as cursors. The user agent retrieves the cursor url() from the first one. If the user agent cannot handle the first cursor of the cursor list, it must try to handle the cursor list and so on. If the user agent cannot handle any of the provided images (see browser support), the cursor keyword must be used. end of list. The optional and coordinates identify the exact location of the pointer position (i.e., the hotspot) in the image.

Non-URL standard cursor keywords must be provided at the end of the fallback list.

:

Use unitless numbers less than 32, negative values ​​are not allowed. These values ​​specify the coordinates of the cursor's hot spot. The first number is the x coordinate and the second number is the y coordinate.

Example:

cursor: url (some-cursor .png) 2 15, pointer;
