- `content`  <**String**> css Source file content
- `minWidth` <**Number**> Optional, Client minimum width(px). default: `320`. If the vw unit is too small, it will not be displayed. For example, 0.0125vw is not displayed on the 320 screen. (v1.2.2 Update)

## API(中文)
### px2vw(width, content[, minWidth[, fixedNum]])

- `width`  <**Number**> 客户端宽度(px)。默认: `320`。
- `content`  <**String**> css源文件内容。
- `minWidth` <**Number**> 可选参数，客户端最小宽度(px)。默认: `320`。如果 vw 单位太小将会不显示。 比如 0.0125vw 在 320 屏上不显示。故设此参数。(1.2.2 更新)
- `fixedNum` <**Number**> 可选参数，小数 `toFixed` 参数。值越小文件越小，但精度也越低。默认: `undefined`(v1.3.0 Update).
