strictcss v0.0.4

strictCSS

Given too much flexibility with CSS, sometimes it's hard to argue about existence of one or another CSS-spec property. This project started of thinking about margin property. Rather than styling given element, it looks like it's trying to fix parent layout. And it's definitely container's job to align elements and spacing them.

So, let's try to see what happen if we try to create more restricted, opinionated approach on CSS.

These tools utilizes styles CSS-in-JS utility and generate styles-friendly code for it.

Banned element properties

• margin

strictCSS

import strictCSS from 'strictcss'

const styles = strictCSS({
    container: {
        display: 'flex',
        flexDirection: 'row',
        ' > div': {
            marginTop: '10px'
        }
    },
    item: {
        marginTop: '10px'
    }
})
// This will cut marginTop property of `item` style and print error in the console.
// Whereas it'll allow margin properties for nested styles, to allow container to style children properly.
// Except that, it works similar to `styles`

layout

import layout from 'scrictcss/layout'

// Used to generate spacing for container children
// As it turns out that neither CSS-grid nor Flexbox are able 
// to give individual per-row/column spacing for content 

layout('column', '* 5px * 10px *')
// Should be read as 
// - given group of three elements
//   - with 5px spacing between 1st and 2nd and
//   - 10px spacing between 2nd and 3rd

// This will produce styling for container
// {
//     ' > :nth-child(3n+1)': {
//         marginBottom: '5px'
//     }
//     ' > :nth-child(3n+2)': {
//         marginBottom: '10px'
//     }
// }
