targetUnit: 'vw&rem'
If you want to use unit vw and also worry about browser support, you can use 'vw&rem' mode. For example:
// Input
.test {
border: 3.75px solid #fff;
}
// Output
.test {
border: 0.1rem solid #fff;
border: 1vw solid #fff;
}For browser doesn't support vw, it will automatically use rem to layout.
Notice: If you need to limit max/min width of the layout, this mode is not suit for you
PX
Convert process is case sensitive, you could use PX in some edge case.
// Input
.test {
padding: 3.75px 3.75px;
}
// Output
.test {
padding: 3.75px 1vw;
