Banana CSS

:banana: The Brazilian CSS superset.

What is?

• Syntax abstractions for complex native CSS features.
• If you can, compile native CSS features like a pre-processor (ex: Custom properties and @import).
• Provide a simple abstraction for a Semantic Grid System with calc().
• Extra features (ex: @function).

How it works?

The bananafile

Create a file called bananafile.json in the directory where you will run the command $ banana and configure as need.

{
	"bnnSize" : true,
	"bnnPosition" : true,
	"bnnGradient" : true,
	"bnnVariable" : true,
	"bnnImport" : true,
	"bnnAlign" : true,
	"bnnWidth" : true,
	"bnnHeight" : true,
	"bnnCol" : true,
	"bnnRow" : true,
	"bnnBox" : true,
	"bnnFunction" : true,
	"compress" : false
}

All features have true as default value, except the compress.

Module Usage

const inputBananaCode = '.a {bnn-size: 50px;}';

// Features injection
const config = {};
config.bnnSize = true;
config.bnnPosition = true;
config.bnnGradient = true;
config.bnnVariable = true;
config.bnnImport = true;
config.bnnAlign = true;
config.bnnWidth = true;
config.bnnHeight = true;
config.bnnCol = true;
config.bnnRow = true;
config.bnnBox = true;
config.bnnFunction = true;
config.compress = true;

const Banana = require('banana')(config);

// Output the css
const output = Banana.render(inputBananaCode);

console.log(output); // .a {width: 50px; height: 50px;}
