README.md

+This project was bootstrapped with [Create React App](https://github.com/facebookincubator/create-react-app).
+
+此为移动端项目在模板基础上添加屏幕适配，以 VW,VH 为单位实现页面适配,添加以下插件
+
+## postcss-cssnext
+
+postcss-cssnext 其实就是 cssnext。该插件可以让我们使用 CSS 未来的特性，其会对这些特性做相关的兼容性处理。其包含的特性主要有：
+
+![cssnext-img](https://www.w3cplus.com/sites/default/files/blogs/2018/1801/vw-layout-4.png)
+
+## cssnano
+
+cssnano 主要用来压缩和清理 CSS 代码。在 Webpack 中，cssnano 和 css-loader 捆绑在一起，所以不需要自己加载它。不过你也可以使用 postcss-loader 显式的使用 cssnano。有关于 cssnano 的详细文档，可以点击这里获取。
+
+在 cssnano 的配置中，使用了 preset: "advanced"，所以我们需要另外安装：
+
+```
+npm i cssnano-preset-advanced --save-dev
+```
+
+cssnano 集成了一些其他的 PostCSS 插件，如果你想禁用 cssnano 中的某个插件的时候，可以像下面这样操作：
+
+```js
+"cssnano": {
+  autoprefixer: false,
+  "postcss-zindex": false
+}
+```
+
+## postcss-aspect-ratio-mini
+
+`postcss-aspect-ratio-mini`主要用来处理元素容器宽高比。在实际使用的时候，具有一个默认的结构，使用方法：
+
+```css
+/* in css */
+[aspectratio] {
+  position: relative;
+}
+[aspectratio]::before {
+  content: '';
+  display: block;
+  width: 1px;
+  margin-left: -1px;
+  height: 0;
+}
+[aspectratio-content] {
+  position: absolute;
+  top: 0;
+  left: 0;
+  right: 0;
+  bottom: 0;
+  width: 100%;
+  height: 100%;
+  overflow: hidden;
+}
+[w-750-260] {
+  aspect-ratio: '750:260';
+}
+```
+
+在实际使用的时候，你可以把自定义属性`aspectratio`和`aspectratio-content`换成相应的类名
+
+```html
+<!-- in html -->
+
+<div aspectratio="" w-750-260="">
+  <div aspectratio-content=""></div>
+</div>
+```
+
+此时内层盒子的大小就是设置的`750:260`的纵横比
+
+## postcss-px-to-viewport
+
+`postcss-px-to-viewport`插件主要用来把`px`单位转换为`vw`、`vh`、`vmin`或者`vmax`这样的视窗单位，也是 vw 适配方案的核心插件之一。
+
+## postcss-write-svg
+
+postcss-write-svg 插件主要用来处理移动端 1px 的解决方案。该插件主要使用的是 border-image 和 background 来做 1px 的相关处理。比如
+
+```css
+@svg 1px-border {
+  height: 2px;
+  @rect {
+    fill: var(--color, black);
+    width: 100%;
+    height: 50%;
+  }
+}
+.example {
+  border: 1px solid transparent;
+  border-image: svg(1px-border param(--color #00b1ff)) 2 2 stretch;
+}
+```
+
+## postcss-viewport-units
+
+`postcss-viewport-units`插件主要是给 CSS 的属性添加`content`的属性，配合`viewport-units-buggyfill`库给`vw`、`vh`、`vmin`和`vmax`做适配的操作。
+
+### 引入 JavaScript 文件
+
+`viewport-units-buggyfill`主要有两个 JavaScript 文件：viewport-units-buggyfill.js 和 viewport-units-buggyfill.hacks.js。你只需要在你的 HTML 文件中引入这两个文件。比如在 Vue 项目中的 `index.html` 引入它们：
+
+```html
+<script src="//g.alicdn.com/fdilab/lib3rd/viewport-units-buggyfill/0.6.2/??viewport-units-buggyfill.hacks.min.js,viewport-units-buggyfill.min.js"></script>
+```
+
+第二步，在 HTML 文件中调用 viewport-units-buggyfill，比如：
+
+```html
+<script> window.onload = function () { window.viewportUnitsBuggyfill.init({ hacks: window.viewportUnitsBuggyfillHacks }); } </script>
+```
