› wp_get_state_declarations_with_fallback_border_styles ( $declarations )
Parameters:
  • (array) $declarations CSS declarations generated by the style engine.
    Required: Yes
Returns:
  • (array) CSS declarations with fallback border styles applied where needed.
Defined at:
Codex:

Adds fallback border-style declarations for visible border declarations.

CSS does not render border color or width unless a border style is also set. State styles are emitted as stylesheet rules rather than inline styles, so they cannot rely on the block-library inline-style attribute fallback rules.
