postcss-auto2remvw

PostCSS plugin auto change px to rem & vw.

Intro

The rem layout is affected by the root font-size, if Android turns on the font-size enlargement mode, it will cause the whole layout to crash.

The viewport scale under Android is forced to 1, some Canvas drawing content is slightly blurred. Some Android devices have bug in changing scale, too many devices are difficult to locate the problem.

This plugin will increase the size of css。

.foo {
  height: 100px;
}

.foo {
  height: 0.133333rem;
  height: 13.333333vw;
}
