简书网站的搭建

项目的搭建

依旧是使用脚手架create-react-app xxx 去搭建自己的项目，然后接下来删除没用的代码：

在以上的项目中呢，只需要留下App.js、index.js、index.css即可，当然还可以留着reportWebVitals.js这个文件，这个是处理离线缓存、消息推送、后台自动更新等任务，不过生产环境不用留。

然后重构index.css为style.js，引入yarn add styled-components这个模块

这里提一嘴啊，慕课那课太老了，api都更新了，在style.js里引入reset

import {createGlobalStyle} from 'styled-components'
export const Globalstyle = createGlobalStyle`
  body {
    html, body, div, span, applet, object, iframe,
    h1, h2, h3, h4, h5, h6, p, blockquote, pre,
    a, abbr, acronym, address, big, cite, code,
    del, dfn, em, img, ins, kbd, q, s, samp,
    small, strike, strong, sub, sup, tt, var,
    b, u, i, center,
    dl, dt, dd, ol, ul, li,
    fieldset, form, label, legend,
    table, caption, tbody, tfoot, thead, tr, th, td,
    article, aside, canvas, details, embed,
    figure, figcaption, footer, header, hgroup,
    menu, nav, output, ruby, section, summary,
    time, mark, audio, video {
      margin: 0;
      padding: 0;
      border: 0;
      font-size: 100%;
      font: inherit;
      vertical-align: baseline;
    }

    /* HTML5 display-role reset for older browsers */
    article, aside, details, figcaption, figure,
    footer, header, hgroup, menu, nav, section {
      display: block;
    }

    body {
      line-height: 1;
    }

    ol, ul {
      list-style: none;
    }

    blockquote, q {
      quotes: none;
    }

    blockquote:before, blockquote:after,
    q:before, q:after {
      content: '';
      content: none;
    }

    table {
      border-collapse: collapse;
      border-spacing: 0;
    }
  }
`

然后在入口文件里引入这个组件！！！！

import {Globalstyle} from './style';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <Globalstyle/>
    <App />
  </React.StrictMode>
);

至此，就可以了。大体轮廓就这样了~~~

接下来开始建立我们的项目了

我们先写头部，所以建立common这个文件夹，因为头部在各个网页是通用的

说明一下：我们有APP这个大组件，然后在APP这个大组件里有Header这个小组件，再把APP渲染到我们的入口文件，也就是index.js里，这就是目前的结构~~

我们在header目录下的style里引入刚刚安装的模块，然后这样的话，就可以在这个文件下编辑header目录下index.js的样式了，也就是头部组件的样式

 我们在header这个目录下的入口文件引入刚刚写的那个小组件，先引入再使用

---

在style.js里导入图片：

import logoPic from '../../statics/logo.png'  //先引入

export const Logo=styled.a.attrs({
  href:'/'
})`
  position: absolute;
  top: 0;
  left: 0;
  display: block;
  width: 100px;
  height: 58px;
  background: url(${logoPic});  //在这里哦  再使用
  background-size: contain;
  `

---

在header目录下的index.js里引入阿里巴巴矢量图标

我们首先到阿里巴巴官网上下载下我们需要的图标，然后在common的目录下新建statics文件夹，引入iconfont，需要的就是这几个：

然后在总的入口文件里引入就可以了：

import './statics/iconfont/iconfont.css'

 就可以在header目录下的index.js里用啦！！！：

<i className='iconfont'>&#xe636;</i>

---

目前效果：

index,js:

import React, {Component} from 'react';
import {
  HeaderWrapper, Logo, Nav,NavItem,NavSearch,Addition,Button,SearchWrapper
} from './style'
class Header extends Component {
  render() {
    return (
      <div>
        <HeaderWrapper>
          <Logo/>
          <Nav>
            <NavItem className='left'>首页</NavItem>
            <NavItem className='left'>下载APP</NavItem>
            <NavItem className='right'>
              <i className='iconfont'>&#xe636;</i>
            </NavItem>
            <NavItem className='right'>登录</NavItem>

            <SearchWrapper>
            <NavSearch></NavSearch>
            <i className='iconfont'>&#xe617;</i>
            </SearchWrapper>
          </Nav>

          <Addition>
            <Button className='writing'>
              <i className='iconfont'>&#xe600;</i>
              写文章
            </Button>
            <Button className='reg'>注册</Button>
          </Addition>

        </HeaderWrapper>
      </div>
    );
  }
}

export default Header;
