dy attribute indicates a shift along the y-axis on the position of an element or its content.

You can use this attribute with the following SVG elements:

• <altGlyph>
• <feDropShadow>
• <feOffset>
• <glyphRef>
• <text>
• <tref>
• <tspan>

范例

html,body,svg { height:100% }

					

<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
  <!-- Lines materialized the position of the glyphs -->
  <line x1="10%" x2="10%"  y1="0"   y2="100%" />
  <line x1="0"   x2="100%" y1="30%" y2="30%"  />
  <line x1="0"   x2="100%" y1="80%" y2="80%"  />
  <!-- Some reference text -->
  <text x="10%" y="30%" fill="grey">SVG</text>
  <!-- The same text with a shift along the y-axis -->
  <text dy="50%" x="10%" y="30%">SVG</text>
</svg>

					

line {
  stroke: red;
  stroke-width: .5px;
  stroke-dasharray: 3px;
}

					

altGlyph

警告： As of SVG2 <altGlyph> is deprecated and shouldn't be used.

For <altGlyph> , if it contains a single value, dy defines a shift along the y-axis for all alternate glyph.

If there are multiple values, dy defines a shift along the y-axis for each individual glyph relative to the preceding glyph. If there are less values than glyphs, the remaining glyphs use a value of 0 . If there are more values than glyphs, extra values are ignored.

值	List of <length>
默认值	none
Animatable	Yes

feDropShadow

For <feDropShadow> , dy defines the y offset of the dropped shadow. The unit used to resolve the value of the attribute is set by the primitiveUnits 属性在 <filter> 元素。

值	<number>
默认值	2
Animatable	Yes

feOffset

For <feOffset> , dy defines the y offset of the filter input graphic. The unit used to resolve the value of the attribute is set by the primitiveUnits 属性在 <filter> 元素。

值	<number>
默认值	0
Animatable	Yes

glyphRef

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

For <glyphRef> , dy defines the y offset of the glyph, in the font metric system.

值	<number>
默认值	0
Animatable	Yes

text

For <text> , if it contains a single value, dy defines a shift along the y-axis for all glyphs.

If there are multiple values, dy defines a shift along the y-axis for each individual glyph relative to the preceding glyph. If there are less values than glyphs, the remaining glyphs use a value of 0 . If there are more values than glyphs, extra values are ignored.

值	List of <length>

tref

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

For <tref> , if it contains a single value, dy defines a shift along the y-axis for all glyphs.

If there are multiple values, dy defines a shift along the y-axis for each individual glyph relative to the preceding glyph. If there are less values than glyphs, the remaining glyphs use a value of 0 . If there are more values than glyphs, extra values are ignored.

tspan

For <tspan> , if it contains a single value, dy defines a shift along the y-axis for all alternate glyph.

If there are multiple values, dy defines a shift along the y-axis for each individual glyph relative to the preceding glyph. If there are less values than glyphs, the remaining glyphs use a value of 0 . If there are more values than glyphs, extra values are ignored.
