SVGTextPathElement: startOffset property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The startOffset read-only property of the SVGTextPathElement interface reflects the X component of the startOffset attribute of the given <textPath>, which defines an offset from the start of the path for the initial current text position along the path after converting the path to the <textPath> element's coordinate system.
