CSS for grabbing cursors (drag & drop)

问题:

I have a JavaScript webapp where the user needs to grab the background to move the whole screen around. So I want the cursor to change when they're hovering over the background. The -moz-grab and -moz-grabbing CSS cursors are ideal for this. Of course, they only work in Firefox... are there equivalent cursors for other browsers? Do I have to do something a little more custom than standard CSS cursors?

回答1:

I think move would probably be the closest standard cursor value for what you're doing:

move
Indicates something is to be moved.

回答2:

In case anyone else stumbles across this question, this is probably what you were looking for:

.grabbable {
    cursor: move; /* fallback if grab cursor is unsupported */
    cursor: grab;
    cursor: -moz-grab;
    cursor: -webkit-grab;
}

 /* (Optional) Apply a "closed-hand" cursor during drag operation. */
.grabbable:active {
    cursor: grabbing;
    cursor: -moz-grabbing;
    cursor: -webkit-grabbing;
}

回答3:

CSS3 grab and grabbing are now allowed values for cursor. In order to provide several fallbacks for cross-browser compatibility including custom cursor files, a complete solution would look like this:

.draggable {
    cursor: move; /* fallback: no `url()` support or images disabled */
    cursor: url(images/grab.cur); /* fallback: Internet Explorer */
    cursor: -webkit-grab; /* Chrome 1-21, Safari 4+ */
    cursor:    -moz-grab; /* Firefox 1.5-26 */
    cursor:         grab; /* W3C standards syntax, should come least */
}
.draggable:active {
    cursor: url(images/grabbing.cur);
    cursor: -webkit-grabbing;
    cursor:    -moz-grabbing;
    cursor:         grabbing;
}

"more custom" than CSS cursors means a plugin of some type, but you can totally specify your own cursors using CSS. I think this list has what you want:

.alias {cursor: alias;}
.all-scroll {cursor: all-scroll;}
.auto {cursor: auto;}
.cell {cursor: cell;}
.context-menu {cursor: context-menu;}
.col-resize {cursor: col-resize;}
.copy {cursor: copy;}
.crosshair {cursor: crosshair;}
.default {cursor: default;}
.e-resize {cursor: e-resize;}
.ew-resize {cursor: ew-resize;}
.grab {cursor: grab;}
.grabbing {cursor: grabbing;}
.help {cursor: help;}
.move {cursor: move;}
.n-resize {cursor: n-resize;}
.ne-resize {cursor: ne-resize;}
.nesw-resize {cursor: nesw-resize;}
.ns-resize {cursor: ns-resize;}
.nw-resize {cursor: nw-resize;}
.nwse-resize {cursor: nwse-resize;}
.no-drop {cursor: no-drop;}
.none {cursor: none;}
.not-allowed {cursor: not-allowed;}
.pointer {cursor: pointer;}
.progress {cursor: progress;}
.row-resize {cursor: row-resize;}
.s-resize {cursor: s-resize;}
.se-resize {cursor: se-resize;}
.sw-resize {cursor: sw-resize;}
.text {cursor: text;}
.url {cursor: url(https://www.w3schools.com/cssref/myBall.cur),auto;}
.w-resize {cursor: w-resize;}
.wait {cursor: wait;}
.zoom-in {cursor: zoom-in;}
.zoom-out {cursor: zoom-out;}

回答5:

You can create your own cursors and set them as the cursor using cursor: url('path-to-your-cursor');, or find Firefox's and copy them (bonus: a nice consistent look in every browser).

回答6:

I may be late, but you can try the following code, which worked for me for Drag and Drop.

.dndclass{
    cursor: url('../images/grab1.png'), auto; 

}

.dndclass:active {
    cursor: url('../images/grabbing1.png'), auto;
}

You can use the images below in the URL above. Make sure it is a PNG transparent image. If not, download one from google.

The closed hand cursor is not 16x16. If you would need them in the same dimensions, here you have both of them in 16x16 px

Or if you need original cursors:
