pointer - CSS: Cascading Style Sheets 编辑

The pointer CSS media feature tests whether the user has a pointing device (such as a mouse), and if so, how accurate the primary pointing device is.

Note: If you want to test the accuracy of any pointing device, use any-pointer instead.

Syntax

The pointer feature is specified as a keyword value chosen from the list below.

none

The primary input mechanism does not include a pointing device.

coarse

The primary input mechanism includes a pointing device of limited accuracy.

fine

The primary input mechanism includes an accurate pointing device.

Examples

This example creates a small checkbox for users with fine primary pointers and a large checkbox for users with coarse primary pointers.

HTML

<input id="test" type="checkbox" />
<label for="test">Look at me!</label>

CSS

input[type="checkbox"] {
  -moz-appearance: none;
  -webkit-appearance: none;
  appearance: none;
  border: solid;
  margin: 0;
}

input[type="checkbox"]:checked {
  background: gray;

    width: 15px;
    height: 15px;
    border-width: 1px;
