dx
The dx attribute indicates a shift along the x-axis on the position of an element or its content.
You can use this attribute with the following SVG elements:
Example
<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
  <!-- Lines materialized the position of the glyphs -->
  <line x1="0" x2="100%" y1="50%" y2="50%" />
  <line x1="10%" x2="10%" y1="0" y2="100%" />
  <line x1="60%" x2="60%" y1="0" y2="100%" />
  <!-- Some reference text -->
  <text x="10%" y="50%" fill="grey">SVG</text>
  <!-- The same text with a shift along the x-axis -->
  <text dx="50%" x="10%" y="50%">SVG</text>
</svg>
line {
  stroke: red;
  stroke-width: 0.5px;
  stroke-dasharray: 3px;
}
feDropShadow
For <feDropShadow>, dx defines the x offset of the dropped shadow. The unit used to resolve the value of the attribute is set by the primitiveUnits attribute of the <filter> element.
| Value | <number> | 
|---|---|
| Default value | 2 | 
| Animatable | Yes | 
feOffset
For <feOffset>, dx defines the x offset of the filter input graphic. The unit used to resolve the value of the attribute is set by the primitiveUnits attribute of the <filter> element.
| Value | <number> | 
|---|---|
| Default value | 0 | 
| Animatable | Yes | 
text
For <text>, if it contains a single value, dx defines a shift along the x-axis for all glyphs.
If there are multiple values, dx defines a shift along the x-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.
| Value | List of (<length> | <percentage>) | 
|---|---|
| Default value | none | 
| Animatable | Yes | 
Example
<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
  <!-- Lines materialized the position of the glyphs -->
  <line x1="0" x2="100%" y1="25%" y2="25%" />
  <line x1="0" x2="100%" y1="50%" y2="50%" />
  <line x1="0" x2="100%" y1="75%" y2="75%" />
  <line x1="10%" x2="10%" y1="0" y2="100%" />
  <line x1="30%" x2="30%" y1="0" y2="100%" />
  <line x1="60%" x2="60%" y1="0" y2="100%" />
  <!-- Behaviors change based on the number
       of values in the attributes -->
  <text dx="20%" x="10%" y="25%">SVG</text>
  <text dx="0 10%" x="10%" y="50%">SVG</text>
  <text dx="0 10% 20%" x="10%" y="75%">SVG</text>
</svg>

}
tspan
For <tspan>, if it contains a single value, dx defines a shift along the x-axis for all alternate glyph.
If there are multiple values, dx defines a shift along the x-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.
