JSS plugin that gives you a better syntax than CSS.
Can you remember what each of those values mean box-shadow: 2px 2px 2px 1px gold;
and in which order they have to be used? Me neither. CSS values are sometimes cryptic. This plugin makes them easy to read and to remember.
Make sure you read how to use plugins in general.
Usage example
const sheet = jss.createStyleSheet({
container: {
padding: [20, 10],
background: {
color: '#000',
image: 'url(image.jpg)',
position: [0, 0],
repeat: 'no-repeat'
},
transition: [
{
property: 'opacity',
duration: '200ms'
},
{
property: 'width',
duration: '300ms'
}
]
}
})
.jss-0-0 {
padding: 20px 10px;
background: #000 url(image.jpg) 0 0 no-repeat;
transition: opacity 200ms, width 300ms;
}
Features
- One syntax for arrays. This plugin simplifies writing values as array of numbers for
margin, padding, border-radius, background-position, transform, transition, animation, box-shadow, text-shadow
:
padding: [20, 10],
border-radius: ['50%', '10%'],
transition: [['opacity', '200ms'], ['width', '300ms']]
instead of comma and space separated syntax from jss:
padding: [[20, 10]],
border-radius: [['50%', '10%']],
transition: [[['opacity', '200ms']], [['width', '300ms']]]
- Writing values as object for
padding, margin, background, border, border-top, border-bottom, border-left, border-right, outline, list-style, transition, animation, box-shadow, text-shadow, flex
border: {
width: '1px',
style: 'solid',
color: '#f00'
}
will be converted to
border: 1px solid #f00;
- Writing values as array of objects
transition: [{
property: 'opacity',
duration: '200ms'
}, {
property: 'width',
duration: '300ms'
}
]
will be converted to
transition: opacity 200ms, width 300ms;

Order does matter
This plugin MUST BE used AFTER jss-camel-case and jss-extend and jss-default-unit and jss-nested
Known issues
This plugin doesn't support font
property written in expanded way. This is because plugin must have maximum performance, and all exceptions like in font
way of writing (joining of font-size
and line-height
joining with \
symbol) is forbidden.
