react基礎使用styled-components編寫js的樣式組件的基本使用

1、安裝styled-components，用於js編寫對應的組件

styled的使用，用於創建組件

import styled from 'styled-components'

export const Item = styled.div`
    width: 350px;
    height: 36px;
    line-height: 36px;
    font-weight: bold;
`

2、createGlobalStyle用於創建全局樣式

import { createGlobalStyle } from 'styled-components'

export const GlobalStyle = createGlobalStyle`
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;
}
`;

3、引用創建的全局樣式

import React from 'react';
import { GlobalStyle } from './style'
import Header from './component/Header'
import { Provider } from 'react-redux'
import store from './store'
function App() {
  return (
    <div className="App">
      <GlobalStyle></GlobalStyle>
      <Provider store={store}>
        <Header></Header>
      </Provider>
    </div>
  );
}

export default App;

4、背景圖片的使用,要從外部引入背景圖片，然後通過變量使用

import logo from '../../statics/logo.png'

background: url(${logo})
