SVG allows graphical objects to be defined for later reuse. It is recommended that, wherever possible, referenced elements be defined inside of a <defs> element. Defining these elements inside of a <defs> element promotes understandability of the SVG content and thus promotes accessibility. Graphical elements defined in a <defs> element will not be directly rendered. You can use a <use> element to render those elements wherever you want on the viewport.
