Bare essentials CSS prefixing helpers in less than 1KB 🌈
Currently supports prefixing properties for most browsers as it makes sense.
See SUPPORT.md
for more information on which prefixes and transformations have been omitted.
The API is fairly straightforward and only consists of two functions, prefixProperty
and prefixValue
.
prefixProperty('margin');
prefixProperty('appearance');
prefixValue('color', 'palevioletred');
prefixValue('position', 'sticky');
prefixProperty
returns a bitmap depending on which prefix should be
applied:
0b001
stands for -ms-
0b010
stands for -moz-
0b100
stands for -webkit
These are combined using a binary OR, so an example usage of the
pefixProperty
helper may look like the following:
const prefix = (prop, value) => {
const flag = prefixProperty(prop);
let css = `${prop}: ${value};\n`;
if (flag & 0b001) css += `-ms-${css}`;
if (flag & 0b010) css += `-moz-${css}`;
if (flag & 0b100) css += `-webkit-${css}`;
return css;
};
