用于抓取游标的CSS（拖放）

Question

我有一个JavaScript webapp，用户需要抓住背景才能移动整个屏幕。所以我希望光标在它们悬停在背景上时发生变化。 -moz-grab和-moz-grabbing CSS游标非常适合这种情况。当然，它们只能在Firefox中运行...是否有其他浏览器的等效游标？我是否必须做一些比标准CSS游标更自定义的东西？

Answer 1

如果其他人偶然发现了这个问题，这可能就是您所寻找的：

.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;
}

Answer 2

我认为move可能是你正在做的最接近的standard cursor value：

  

<强>移动
  表示要移动的东西。

Answer 3

CSS3 grab和grabbing现在是cursor的允许值。 为了为cross-browser compatibility提供包含自定义光标文件的多个后备，完整的解决方案将如下所示：

.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;
}

“自定义”比CSS游标意味着某种类型的插件，但您可以使用CSS完全指定自己的游标。我认为这个清单有你想要的东西：

.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;}

Answer 5

您可以使用cursor: url('path-to-your-cursor');创建自己的游标并将其设置为光标，或者找到Firefox并复制它们（奖励：在每个浏览器中都有一致的外观）。

Answer 6

我可能会迟到，但您可以尝试以下代码，这对我来说是拖拽。

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

}

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

您可以在上面的网址中使用以下图片。确保它是PNG透明图像。如果没有，请从谷歌下载一个。

Answer 7

闭合的手形光标不是16x16。如果您需要它们具有相同的尺寸，则这两个尺寸均为16x16 px

或者如果您需要原始光标：
