SVG defs
Syntax
<defs>... defined elements ...</defs>
Parameters
| Parameter | Details |
|---|---|
| defs | The defs element has no parameters |
Remarks
The <defs> element is used as a container element for elements that are intended to be used solely by reference and not rendered directly. Elements that would normally be rendered (e.g. <rect>, <circle>) that are declared inside a <defs> block are treated as if their style included display:none.
Although it's not strictly necessary, the SVG spec. recommends putting all gradient, filter, pattern, mask, symbol, and marker definitions within a defs block.
