用于抓取光标（拖放）的 CSS

Question

我有一个 JavaScript Web 应用程序，用户需要抓住背景来移动整个屏幕。所以我希望当它们悬停在背景上时光标发生变化。 -moz-grab 和 -moz-grabbing CSS 光标非常适合此目的。当然，它们仅适用于 Firefox...其他浏览器是否有等效的光标？我是否需要做一些比标准 CSS 光标更自定义的事情？

Answer 1

如果其他人偶然发现这个问题，这可能就是您正在寻找的：

.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 可能是最接近的标准光标您正在做的事情的价值：

移动
表示有东西要移动。

CSS3 抓取 和 抓取 现在是 cursor 允许的值。
为了提供跨浏览器兼容性的多种后备方案3 包括自定义光标文件，完整的解决方案如下所示：

.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;
}

更新2019-10-07：

.draggable {
    cursor: move; /* fallback: no `url()` support or images disabled */
    cursor: url(images/grab.cur); /* fallback: Chrome 1-21, Firefox 1.5-26, Safari 4+, IE, Edge 12-14, Android 2.1-4.4.4 */
    cursor: grab; /* W3C standards syntax, all modern browser */
}

.draggable:active {
    cursor: url(images/grabbing.cur);
    cursor: grabbing;
}

比 CSS 光标“更自定义”意味着某种类型的插件，但您完全可以使用 CSS 指定自己的光标。我认为这个列表有你想要的：

.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

我可能会迟到，但您可以尝试以下代码，该代码对我来说适用于拖放。

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

}

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

您可以在上面的 URL 中使用下面的图像。确保它是 PNG 透明图像。如果没有，请从谷歌下载一个。

Answer 6

您可以创建自己的光标并使用 cursor: url('path-to-your-cursor'); 将它们设置为光标，或者找到 Firefox 的光标并复制它们（好处：外观一致每个浏览器）。

Answer 7

闭合的手形光标不是 16x16。如果您需要相同尺寸的它们，这里您可以将它们都设置为 16x16 px

或者，如果您需要原始光标：
