foreignObject

For <foreignObject>, x defines the  x coordinate of the uper left corner of its viewport.

Note: Starting with SVG2, x is a Geometry Property meaning this attribute can also be used as a CSS property for <foreignObject>.

Warning: As of SVG2 <glyphRef> is deprecated and shouldn't be used.

For <glyphRef>, x defines the x-axis coordinate of the glyph.

image

For <image>, x defines the  x coordinate of the uper left corner of the image.

Note: Starting with SVG2, x is a Geometry Property meaning this attribute can also be used as a CSS property for images.

mask

For <mask>, x defines the  x coordinate of the uper left corner of its area of effect. The exact effect of this attribute is influenced by the maskUnits attribute.

pattern

For <pattern>, x defines the  x coordinate of the uper left corner of the tile pattern. The exact effect of this attribute is influenced by the patternUnits and patternTransform attributes.

rect

For <rect>, x defines the  x coordinate of the uper left corner of the shape.

Note: Starting with SVG2, x is a Geometry Property meaning this attribute can also be used as a CSS property for rectangles.

svg

For <svg>, x defines the  x coordinate of the uper left corner of its viewport.

Note: Starting with SVG2, x is a Geometry Property meaning this attribute can also be used as a CSS property for <svg>.

text

For <text>, if it contain a single value, x defines the x coordinate on where the content text position must be placed. The content text position is usualy a point on the baseline of the first line of text. The exact content text position is influenced by some properties like text-anchor, or direction.

If there are multiple values, x defines the x coordinate of each individual glyph from the text. If there are less values than glyphes, the remaining glyphes are placed in the continuity of the last positioned glyph. If there are more values than glyphes, extra values are ignored.

Example

html,body,svg { height:100% }

<svg viewBox="0 0 200 100" xmlns="http://www.w3.org/2000/svg">
  <!-- horizontal line to materialized the text base line -->

  <!-- vertical line to materialized the x positioning -->
  <line x1="25%" y1="0" x2="25%" y2="100%" />
  <line x1="50%" y1="0" x2="50%" y2="100%" />
  <line x1="75%" y1="0" x2="75%" y2="100%" />

  <!-- x with a single value -->
  <text y="40%" x="50%">SVG</text>

  <!-- x with multiple values -->
  <text y="90%" x="25%, 50%, 75%">SVG</text>

tref

Warning: As of SVG2 <tref> is deprecated and shouldn't be used.

For <tref>, if it contain a single value, x defines the x coordinate on where the content text position must be placed. The content text position is usualy a point on the baseline of the first line of text. The exact content text position is influenced by some properties like text-anchor, or direction.

If there are multiple values, x defines the x coordinate of each individual glyph from the text. If there are less values than glyphes, the remaining glyphes are placed in the continuity of the last positioned glyph. If there are more values than glyphes, extra values are ignored.

tspan

For <tspan>, if it contain a single value, x defines the x coordinate on where the content text position must be placed. The content text position is usualy a point on the baseline of the first line of text. The exact content text position is influenced by some properties like text-anchor, or direction.

If there are multiple values, x defines the x coordinate of each individual glyph from the text. If there are less values than glyphes, the remaining glyphes are placed in the continuity of the last positioned glyph. If there are more values than glyphes, extra values are ignored.

use

For <use>, x defines the  x coordinate of the uper left corner of the referenced element.

Note: Starting with SVG2, x is a Geometry Property meaning this attribute can also be used as a CSS property for used elements.
