y1

The y1 attribute is used to specify the first y-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the y attribute instead.

Elements

You can use this attribute with the SVG elements described in the sections below.

<line>

For <line>, y1 defines the y coordinate of the starting point of the line.

Value <length> | <percentage> | <number>
Default value 0
Animatable Yes
<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
  <line x1="1" x2="9" y1="1" y2="5" stroke="red" />
  <line x1="1" x2="9" y1="5" y2="5" stroke="green" />
  <line x1="1" x2="9" y1="9" y2="5" stroke="blue" />

<linearGradient>

For <linearGradient>, y1 defines the y coordinate of the starting point of the gradient vector used to map the gradient stop values. The exact behavior of this attribute is influenced by the gradientUnits attributes
