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.

You can use this attribute with the following SVG elements:

• <line>
• <linearGradient>

范例

html,body,svg { height:100% }

								

<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.

html,body,svg { height:100% }

								

<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 属性

html,body,svg { height:100% }

								

<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>
