## Introduction

CSSQL, developed by mcnuttandrew, presents a truly unconventional solution to front-end styling by enabling the creation of CSS through a SQL DDL-like syntax. This project playfully challenges the traditional JavaScript/CSS debate, offering a "forbidden third option": CSS in SQL. The core philosophy behind CSSQL is to treat CSS selectors as relational database tables, complete with set-like behaviors, allowing for a unique mental model where you "create a series of nestable tables" for your styles. While the transpiler is written in Haskell, it's conveniently distributed for JavaScript environments using GHCJS.

## Installation

To integrate CSSQL into your Node.js project, you can install the `node-cssql` package:

sh
npm install node-cssql


Once installed, you can use it to transpile your `.cssql` files to `.css`:

js
const {cssql} = require('node-cssql');

cssql('./test/tests/join.cssql', './test/tests/join.css');


## Examples

CSSQL introduces a set of SQL-inspired commands to manage your styles. Here's a look at some fundamental operations:

cssql

CREATE SELECTOR .margin-huge-top;
INSERT .margin-huge-top (margin-top, 50px);

CREATE SELECTOR .margin-huge-bottom;
INSERT .margin-huge-bottom (margin-bottom, 50px);

CREATE SELECTOR .margin-huge-left;
INSERT .margin-huge-left (margin-left, 50px);

CREATE SELECTOR .margin-huge-right;
INSERT .margin-huge-right (margin-right, 50px);

MERGE .margin-huge-top AND .margin-huge-bottom AND .margin-huge-left AND .margin-huge-right AS .margin-huge;

DROP .margin-huge-left;



This CSSQL code will transpile into the following CSS:

css
.margin-huge-top {
  margin-top: 50px;
}
.margin-huge-bottom {
  margin-bottom: 50px;
}
.margin-huge-right {
  margin-right: 50px;
}
.margin-huge {
  margin-bottom: 50px;
  margin-left: 50px;
  margin-right: 50px;
  margin-top: 50px;
}

## Why Use CSSQL?

While CSSQL is presented with a humorous, self-aware tone regarding its "esoteric" nature and potential to increase verbosity, it offers a fascinating perspective on language design and front-end development. It challenges conventional approaches by framing CSS selectors and their cascade behavior through the lens of relational databases. For developers interested in exploring alternative paradigms, functional programming (Haskell), or simply curious about pushing the boundaries of what's possible with styling languages, CSSQL provides a unique and thought-provoking project. It's a testament to creative problem-solving, even if the "problem" is intentionally made more complex.
