defs

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.

Basic <defs> example

<svg width="400px" height="400px">
<defs>
  <rect id="defrect" fill="blue" fill-opacity=".5" x="50" y="50" width="100" height="100"/>
</defs>

<rect fill="red" x="20" y="20" width="80" height="80"/>
<use xlink:href="#defrect"/>
<use xlink:href="#defrect" x="50" y="60"/>

</svg>
