x1

The x1 attribute is used to specify the first x-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the x attribute instead.

Two elements are using this attribute: <line>, and <linearGradient>

<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
  <line x1="1" x2="5" y1="1" y2="9" stroke="red" />
  <line x1="5" x2="5" y1="1" y2="9" stroke="green" />
  <line x1="9" x2="5" y1="1" y2="9" stroke="blue" />
</svg>

line

For <line>, x1 defines the x coordinate of the starting point of the line.

Value <length> | <percentage>
Default value 0
Animatable Yes

Example

<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
  <line x1="1" x2="5" y1="1" y2="9" stroke="red"   />
  <line x1="5" x2="5" y1="1" y2="9" stroke="green" />
  <line x1="9" x2="5" y1="1" y2="9" stroke="blue"  />
</svg>

linearGradient

For <linearGradient>, x1 defines the  x 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 attributs

Value <length> | <percentage>
Default value 0%
Animatable Yes

Example

<svg viewBox="0 0 20 10" xmlns="http://www.w3.org/2000/svg">
  <!--
  By default the gradient vector start at the left
  bounding limit of the shape it is applied to
  -->
  <linearGradient x1="0%" id="g0">
    <stop offset="0"    stop-color="black"  />
    <stop offset="100%" stop-color="red" />
  </linearGradient>

  <rect x="1"  y="1" width="8" height="8" fill="url(#g0)" />

  <!--
  Here the gradient vector start at 80% of the left
  bounding limit of the shape it is applied to
  -->
  <linearGradient x1="80%" id="g1">
    <stop offset="0"    stop-color="black"  />
    <stop offset="100%" stop-color="red" />
  </linearGradient>

  <rect x="11" y="1" width="8" height="8" fill="url(#g1)" />
</svg>
