Deprecated since SVG 2
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
kerning attribute indicates whether the spacing between glyphs should be adjusted based on kerning tables that are included in the relevant font (i.e., enable auto-kerning) or instead disable auto-kerning and set the spacing between them to a specific length (typically, zero).
Note: As a presentation attribute
kerning can be used as a CSS property. In CSS the property is called
<svg viewBox="0 0 150 125" xmlns="http://www.w3.org/2000/svg"> <text x="10" y="30" kerning="auto">auto</text> <text x="10" y="70" kerning="0">number</text> <text x="10" y="110" kerning="20px">length</text> </svg>
- This value indicates that the spacing between glyphs is adjusted based on kerning tables that are included in the font that will be used.
If a length is provided, then auto-kerning is disabled. Instead, inter-character spacing is set to the given length.
If a length is provided without a unit identifier (e.g., an unqualified number such as 128), the length is processed as a width value in the current user coordinate system. If a unit identifier (e.g.,
1%) is provided, then the length is converted into a corresponding value in the current user coordinate system.
The most common scenario, other than
auto, is to set
kerningto a value of
0so that auto-kerning is disabled.
The given length is added to the inter-character spacing value specified by the
