postcss-flexible-rpx v0.0.2

postcss-flexible-rpx

Forked from postcss-flexible

This is a postcss plugin for translatingrx, rem(...), dpr(...), url(...). Similar to px2rem, but using custom function istead of comments for syntax.

rpx is to replace the rem(...) because the rpx is more concise. Futhermore, rx is to replace rpx for concise.

Install

npm i postcss-flexible-rpx -D
