在伪元素未出现在路径元素之前
Before pseudo element not showing up on path element
您好,我正在尝试在整个世界的 SVG 地图上创建一个 'pin',SVG 是使用路径元素构建的,我的想法是使用前元素或后元素并相应地显示图钉。
显然它没有显示在路径元素上,我可以在 debugger/console 中看到它,如果我把它放在 div 元素上它工作正常并显示出来,我已经剪掉了为简单起见,除了 SVG 中的第一个国家之外的所有国家/地区。

我还尝试了一种更简单的方法,即在所有路径元素之后在 SVG 中添加一个元素,但这会破坏整个 SVG。
任何人都可以帮助我,在 SVG 路径元素中是不可能的吗?如果可以,我还有哪些其他选择?

正如我评论过的,路径不能有 before 伪元素。但是,在您的情况下,您可以为 pin 设置一个符号,并在文档末尾使用它。这样它将保持在所有其他路径之上。 (z-index 在 SVG 中也不起作用)。
如果您使用带有 viewBox
属性的 symbol
,您可以给 <use>
元素一个位置(x
和 y
属性)和尺寸(width
和 height
属性)
