dy attribute indicates a shift along the y-axis on the position of an element or its content. What exactly is shifted depends on the element for which this attribute is set.
<feOffset> element, it's a <number> that represents the amount to offset the input graphic. This amount is expressed in the coordinate system established by the
primitiveUnits attribute on the
If a single <length> is provided, this value represents the new relative Y coordinate for the current text position for the first character within this element or any of its descendents. The current text position is shifted along the y-axis of the current user coordinate system by <length> before the first character is rendered.
If a comma- or space-separated list of n <length>s is provided, then the values represent incremental shifts along the y-axis for the current text position of the first n characters within this element or any of its descendents. Thus the current text position resulting from drawing the character within the current
<text> element is shifted along the Y axis of the current user coordinate system by <length>.
If more characters exist than <length>s, then for each of these extra characters:
- if an ancestor
<tspan>element specifies a relative Y coordinate for the given character via a
dyattribute, then the current text position is shifted along the y-axis of the current user coordinate system by that amount (nearest ancestor has precedence),
- else no extra shift along the y-axis occurs.
