How to migrate from Windi utility-first CSS framework to Stylify CSS
This guide is here to help you quickly compare the features and syntax of the Windi utility-first CSS framework with those of Stylify, and give you an idea of how to migrate from Windi to Stylify.
Introduction
Windi CSS is an on-demand alternative to Tailwind, which provides faster load times, full compatibility with Tailwind v2.0, and a bunch of additional cool features.
Stylify CSS is a library that uses native CSS-like selectors color:blue
, width:640px
, margin:0_auto
along with variables, components, custom selectors to generate optimized CSS dynamically based on what you write.
Selectors and CSS Utilities
In Windi, you can use utilities directly on the element. Selectors (groups) can also contain a space:
<div class="
py-8 px-8 max-w-sm mx-auto
sm:(py-4 flex items-center space-y-0 space-x-6)
">
</div>
Stylify uses CSS-like utilities, that can be used directly within the class attribute. There are no shortcuts by default and selectors cannot contain a space because of the further optimization:
<div class="
color:blue
font-weight:bold
md:color:red
md&&landscape:font-size:32px
minw123px:font-size:123px
"></div>
When some selectors have the same pseudo-class or even media query, you can group them like this:
<div class="
hover:{color:blue;text-decoration:underline}
md:hover:{transform:scale(1.1);left:4px}
"></div>
Global Selectors
I could not find any information suggesting that Windi provides something like dynamic Global Selectors.
Stylify provides custom selectors with which you can style elements globally. These selectors can be defined directly within the class attribute or in the global config or in a file where they are used using content options.
Example with the class attribute:
<div class="[.button_.icon]{font-size:14px}">
<button class="
[.icon]{color:#fff;border-radius:12px}
[&+button]{margin-left:24px}
">
<i class="icon"></i>
</button>
<button></button>
<div>
The syntax pattern in the class attribute looks like this:
[css selectors]{stylify selectors split by ;}
The _
(underscore) is used instead of space in both CSS and Stylify selectors and the &
character always refers to the current element.
The same code but in the global config would look like this:
const compilerConfig = {
customSelectors: {
'.buttons-wrapper .button .icon': 'font-size:14px',
'.button': `
.icon { color:#fff border-radius:12px }
& + button { margin-left:24px }
`,
}
}
When defining `customSelectors` in the global config on through content options, the syntax lets you use a nesting feature. The &
characters refers to the upper level like in the SCSS.
Usage of the global config:
<div class="buttons-wrapper">
<button class="button">
<i class="icon"></i>
</button>
<button></button>
<div>
Components
In Windi, components be defined within a plugin like this:
import plugin from 'windicss/plugin'
plugin(({ addComponents }) => {
addComponents({
'.btn': {
padding: '.5rem 1rem',
borderRadius: '.25rem',
},
})
})
You can also define a shortcut:
export default {
shortcuts: {
'btn': {
'color': 'white',
'@apply': 'py-2 px-4 font-semibold rounded-lg',
'&:hover': {
'@apply': 'bg-green-700',
'color': 'black',
},
},
},
}
Stylify doesn't provide any predefined CSS Components by default. However, it provides two ways to define them and there is a set of copy&paste Headless Components you can use in your project.
Components can be configured in a file (using content options), where they are used, or globally within a $projectConfig.
Example with the configuration within a file. The content between stylify-components
expects javascript object without surrounding brackets:
<!--
stylify-components
title: 'color:blue font-weight:bold md:color:red'
/stylify-components
-->
<h1 class="title"></h1>
Example in a global compiler config:
const compilerConfig = {
components: {
title: 'color:blue font-weight:bold md:color:red'
}
};
Usage:
<h1 class="title"></h1>
When defining component, you can also use nesting syntax like in SCSS. This works in a global config and also in the content options:
const compilerConfig = {
components: {
button: `
color:black font-weight:bold
&:hover { color:grey }
&--red {
color:red
&:hover { color: darkred }
}
`
}
};
Configuration, Customization and Variables
In Windi you configure a theme in the config file.
import { defineConfig } from 'windicss/helpers'
import colors from 'windicss/colors'
import plugin from 'windicss/plugin'
export default defineConfig({
darkMode: 'class',
theme: {
extend: {
screens: {
'sm': '640px',
},
colors: {
blue: colors.sky,
},
fontFamily: {
sans: ['Graphik', 'sans-serif'],
},
spacing: {
128: '32rem',
},
borderRadius: {
'4xl': '2rem',
},
},
},
})
In Stylify, there is nothing like a "theme", neither extend section in $projectConfig. There are only variables.
Variables can be defined in two ways in Stylify. In a global config or within a file where they are used via content options.
Example with global config:
const compilerConfig = {
variables: {
primary: '#000',
secondary: '#eee',
titleFontSize: '24px',
shadow: '0 2px 3px #000'
}
}
Variables can also be defined based on media query:
const compilerConfig = {
variables: {
dark: { blue: 'lightblue' },
md: { fontSize: 24px },
'minw640px': { fontSize: 32px },
// When screen is not found, it falls back to a random custom selector
'.dark': { blue: 'lightblue' },
':root[data-theme="dark"]': { blue: 'lightblue' }
}
}
Example with content options:
<!--
stylify-variables
primary: '#000',
secondary: '#eee'
titleFontSize: '24px',
shadow: '0 2px 3px #000'
/stylify-variables
-->
<div class="color:$primary"></div>
