更改Mapbox导航控件缩放图标颜色

Question

我设法添加地图导航控件，删除指南针并更改缩放控件背景和不透明度。但是'+'和' - '图标呢？如果可以的话，如何更改图标颜色？

Answer 1

由于按钮图像是通过svg文件设置的，因此它们的颜色不能直接由CSS样式更改。但您可以指定外部图标的链接或覆盖svg中的填充颜色：

/** fill%3A%23333333 -> fill%3A%23ff0000 **/

.mapboxgl-ctrl-zoom-in {
  background-image: url(data:image/svg+xml;charset=utf8,<svg%20viewBox%3D%270%200%2020%2020%27%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27>%0A%20%20<path%20style%3D%27fill%3A%23ff0000%3B%27%20d%3D%27M%2010%206%20C%209.446%206%209%206.4459904%209%207%20L%209%209%20L%207%209%20C%206.446%209%206%209.446%206%2010%20C%206%2010.554%206.446%2011%207%2011%20L%209%2011%20L%209%2013%20C%209%2013.55401%209.446%2014%2010%2014%20C%2010.554%2014%2011%2013.55401%2011%2013%20L%2011%2011%20L%2013%2011%20C%2013.554%2011%2014%2010.554%2014%2010%20C%2014%209.446%2013.554%209%2013%209%20L%2011%209%20L%2011%207%20C%2011%206.4459904%2010.554%206%2010%206%20z%27%20%2F>%0A<%2Fsvg>%0A) !important;
