href
The href
attribute defines a link to a resource as a reference URL. The exact meaning of that link depends on the context of each element using it.
Note: Specifications before SVG 2 defined an xlink:href
attribute, which is now rendered obsolete by the href
attribute. If you need to support earlier browser versions, the deprecated xlink:href
attribute can be used as a fallback in addition to the href
attribute, e.g. <use href="some-id" xlink:href="some-id" x="5" y="5" />
.
You can use this attribute with the following SVG elements:
Example
html
<svg viewBox="0 0 160 40" xmlns="http://www.w3.org/2000/svg">
<a href="https://developer.mozilla.org/">
<text x="10" y="25">MDN Web Docs</text>
</a>
</svg>
In SVG
a
animate, animateMotion, animateTransform, set
For the <animate>
, <animateMotion>
, <animateTransform>
, and <set>
, href
defines a URL referring to the element which is the target of this animation element and which therefore will be modified over time.
The URL must point to exactly one target element which is capable of being the target of the given animation element. If the URL points to multiple target elements, if the given target element is not capable of being a target of the given animation element, or if the given target element is not part of the current document, then the animation element will not affect any target element. However, the animation element will still operate normally with regard to its timing properties. Specifically, TimeEvents are dispatched and the animation element can be used as syncbase in an identical fashion to when the URL refers to a valid target element.
If the href
attribute or the deprecated xlink:href
attribute is not provided, then the target element will be the immediate parent element of the current animation element. If both xlink:href
and href
are specified, the value of the latter attribute is used.
Refer to the descriptions of the individual animation elements for any restrictions on what types of elements can be targets of particular types of animations.
Except for any SVG-specific rules explicitly mentioned in this specification, the normative definition for this attribute is the SMIL Animation specification. In particular, see SMIL Animation: Specifying the animation target.
Value | <url> |
---|---|
Default value | None |
Animatable | No |
feImage
For <feImage>
, href
defines a URL referring to an image resource or to an element. If both, the xlink:href
and the href
attribute are specified, the latter overrides the former.
Value | <url> |
---|---|
Default value | None |
Animatable | Yes |
image
linearGradient
For <linearGradient>
, href
defines URL referring to a template gradient element; to be valid, the reference must be to a different <linearGradient>
or <radialGradient>
element.
Value | <url> |
---|---|
Default value | None |
Animatable | Yes |
mpath
For <mpath>
, href
defines a URL referring to the <path>
element or basic shape which defines the motion path.
Value | <url> |
---|---|
Default value | None |
Animatable | No |
pattern
For <pattern>
, href
defines a URL referring to a different <pattern>
element within the current SVG document. Any attributes which are defined on the referenced element which are not defined on this element are inherited by this element. If this element has no children, and the referenced element does (possibly due to its own href
attribute), then this element inherits the children from the referenced element. Inheritance can be indirect to an arbitrary level; thus, if the referenced element inherits attributes or children due to its own href
attribute, then the current element can inherit those attributes or children. On the <pattern>
element, the href
attribute is animatable.
Value | <url> |
---|---|
Default value | None |
Animatable | Yes |
radialGradient
For <radialGradient>
, href
defines URL referring to a template gradient element; to be valid, the reference must be to a different <linearGradient>
or <radialGradient>
element.
Value | <url> |
---|---|
Default value | None |
Animatable | Yes |
script
textPath
For <textPath>
, href
defines a URL referring to the <path>
element or basic shape onto which the text will be rendered if no path
attribute is provided. On the <textPath>
element, the href
attribute is animatable.
Value | <url> |
---|---|
Default value | None |
Animatable | Yes |
use
For <use>
, href
defines a URL referring to an element or fragment within an SVG document to be cloned.
The <use>
element can reference an entire SVG document by specifying an href
value without a fragment. Such references are taken to be referring to the root element of the referenced document.
Value | <url> |
---|---|
Default value | None |
Animatable | Yes |
