FSCSS Variable Fallback Operator (||)

via Dev.to JavaScriptFSCSS tutorial1mo ago

FSCSS v1.1.13 introduces a new feature: Variable Fallback Operator You can now define a default value directly inside a variable declaration using: property: $/variable || fallback; FSCSS resolves the value in this order: If the variable exists → use it Otherwise → use the fallback value Example Component Definition str ( Button # 1 , " background: $/bg || #06f; color: $/color || #fff; border: $/border || 2px solid; padding: 10px; border-radius: 20px; " ) Usage .btn { $bg : linear-gradient ( 40deg , #aaf , #000 ); $color : #020 ; Button #1 } If a variable is not provided, FSCSS automatically applies the fallback.
