很酷,我只是意识到在CSS中有一些 flood-color
和 lighting-color
。有谁知道什么是泛色
和 lighting-colour
,它们做什么?
Way cool, i'd just realised there is something called flood-color
and lighting-color
in CSS. Does anyone know what is a flood-color
and lighting-color
and what do they do?
这些是什么意思?
'flood-color'使用溢出
当前过滤器原子子区域。关键字currentColor和ICC
颜色可以以与'fill'和'stroke'属性的
规范相同的方式指定。
The ‘flood-color’ property indicates what color to use to flood the current filter primitive subregion. The keyword currentColor and ICC colors can be specified in the same manner as within a specification for the ‘fill’ and ‘stroke’ properties.
'lighting-color'属性定义过滤器原语'feDiffuseLighting'和'feSpecularLighting'的光源的颜色
。
The ‘lighting-color’ property defines the color of the light source for filter primitives ‘feDiffuseLighting’ and ‘feSpecularLighting’.
我们如何应用这些所谓的 SVG 效果?我尝试将灯光颜色设置为红色,但似乎没有任何效果。
How do we apply these so-called SVG effects? I've tried setting the lighting-color to red but there doesn't seem to be any effect whatsoever.
