SCSS
- t3foundation will compile your extension's SCSS files. But not only that.
 - t3foundation integrates your TYPO3 constants into your SCSS files!
 
Sample
// EXT:my_ext/Configuration/TypoScript/constants.typoscript
plugin.my_ext.background-color = #DEDEDE
plugin.my_ext.font-famliy      = Sans, Arial, Courier
...
// EXT:my_ext/Configuration/TypoScript/setup.typoscript
lib.scssVariables.background-color = {$plugin.my_ext.background-color}
lib.scssVariables.font-famliy      = {$plugin.my_ext.font-famliy}
...
            
        Copied!
    
// EXT:my_ext/Resources/Public/Scss/_variables.scss
$background-color = #FFFFFF !default
$font-famliy      = Courier, Arial !default 
...
            
        Copied!
    
Workflow
- t3foundation compiles the SCSS files.
 - If there is a 
lib.array in the TypoScript setup, t3foundation will take each element and replace its value in an SCSS file if there is a variable with the same name and a value marked !default.scss Variables  - Pay attention to unique variables in your SCSS files. If you have defined a variable twice, the value substitution may not be correct.
 
Foundation variables

search for !default in EXT:.
