pointsAtX
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The pointsAtX attribute represents the x location in the coordinate system established by attribute primitiveUnits on the <filter> element of the point at which the light source is pointing.
You can use this attribute with the following SVG elements:
Example
html,
body,
svg {
height: 100%;
}
html
<svg viewBox="0 0 420 200" xmlns="https://www.w3.org/2000/svg">
<filter id="lighting1" x="0" y="0" width="100%" height="100%">
<feDiffuseLighting in="SourceGraphic">
<feSpotLight x="60" y="60" z="50" pointsAtX="0" />
</feDiffuseLighting>
</filter>
<filter id="lighting2" x="0" y="0" width="100%" height="100%">
