vw-polyfill
Make viewport units (vw) work in unsupported browsers
Advantage
- small: less ran 1kb (after gzip)
- simply: just insert one file
- safe: insert vw element to test browser support or not -> if unSupport: convert vw to rem -> set root font-size let 1rem=1vw
Usage
npm
npm i vw-polyfill --save // main.js
import vwPolyfill from "vw-polyfill"
vwPolyfill.init()
// 部分异步加载的CSS文件，可在渲染完成后重新调用 vwPolyfill.init() 方法
// reRander: vwPolyfill.init()
cdn
<body>
<!-- after main script -->
<script src="path/to/vw-polyfill.min.js"></script>
<!-- 默认自动调用，如需重新调用，使用： -->
<!-- auto run init, if you need reRander: -->
<!-- window.__vwPolyfill.init() -->
</body>gulp
- use webpack/gulp/grunt inject plugin into html （E: gulp-inject）
Limitations
- only support vw unit, for layout, (vin/vmax/vh ✘)
- only support link and style tag css in head, （E: <div style="width: 100vw" ✘）
- unsupported old IEs (IE 4-8 ✘)
Effect
Changelog

0.1.0 (November 6st 2020)
- 修复部分浏览器（ios微信webview）宽度无法正常获取的问题
- ！！！不支持vw单位的浏览器，会修改font-size，依赖全局font-size大小的字体会受影响，建议在上添加默认font-size，不要依赖的font-size
