我想定义一个标记，然后能够在不同的地方使用，但颜色不同。
例如：
<?xml version="1.0" standalone="no"?>
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1"
viewBox="0 0 180 320">
<defs>
<marker class="AsteriskMarkerClass" id="AsteriskMarker" viewBox="-1 -1 2 2" stroke-width="0.1">
<line x1="0" y1="-1" x2="0" y2="1" />
<line x1="-1" y1="0" x2="1" y2="0" />
<line x1="-0.7071" y1="-0.7071" x2="0.7071" y2="0.7071" />
<line x1="-0.7071" y1="0.7071" x2="0.7071" y2="-0.7071" />
</marker>
</defs>
.AsteriskMarkerClass { stroke:red; }
<path d="M 60,100"
stroke-width="10"
marker-start="url(#AsteriskMarker)" />
.AsteriskMarkerClass { color:green; }
<path d="M 90,140"
stroke-width="10"
marker-start="url(#AsteriskMarker)" />
</svg>
如果有人可以告诉我如何做到这一点，我会很感激。
解决方法
Properties inherit into the ‘marker’ element from its ancestors;
properties do not inherit from the element referencing the ‘marker’
element.
SVG2允许你说你想要引用元素的样式：
Properties inherit into the ‘marker’ element from its ancestors;
properties do not inherit from the element referencing the ‘marker’
element. Note however that by using the context-stroke value for the
‘fill’ or ‘stroke’ on elements in its definition,a single marker can
be designed to match the style of the element referencing the marker.
请参阅this section中的示例2，了解如何使用该规范。请注意，这是编辑草稿，语法可能仍然会改变。上下文填充和上下文笔画的实现尚未在所有浏览器中使用。如果你正在寻找要测试的东西，似乎是用一个前缀来实现的(可能在一个pref标志之后，我不清楚哪个标志，但可能是gfx.font_rendering.opentype_svg.enabled)在Firefox Nightlies，见WG discussion here。
