The <desc>
element provides an accessible, long-text description of any SVG container element or graphics element.
Text in a <desc>
element is not rendered as part of the graphic. If the element can be described by visible text, it is possible to reference that text with the aria-describedby
attribute. If aria-describedby
is used, it will take precedence over <desc>
.
The hidden text of a <desc>
element can also be concatenated with the visible text of other elements using multiple IDs in an aria-describedby
value. In that case, the <desc>
element must provide an ID for reference.
