Detailed Description

Selectors which start with two colons are called pseudo-elements, e.g.

'::before'. They are used to represent elements which are not directly present in the document tree.

See https://www.w3.org/TR/selectors-4/#pseudo-elements for the full definition.

Pseudo-elements are listed in the CSS Pseudo-Elements Module Level 4 spec: https://www.w3.org/TR/css-pseudo-4/

For SVG, there are no supported pseudo-elements, however pseudo-classes are supported.
