style-components的基本使用

官方文檔:https://www.styled-components.com/docs/basics

安裝：npm install --save styled-components ||  yarn add styled-components

 

個人這個都是在一個組件中操做的，分頁面建立style-components須要導出( export const 自定義名 = 準備建立style的名字 )在須要頁面解構賦值引入

基礎用法：

style-components最基礎的用法就是以組件的形式編寫樣式

 

import styled from 'styled-components';

const HomeWrapper = styled.div `
  width: 960px;
  margin: 0 auto;
  overflow: hidden;
`;
const HomeLeft = styled.div `
  float: left;
  width: 625px;
  margin-left: 15px;
  padding-top: 30px;
  .bannder-img {
    width: 625px;
    height: 270px;
  }
`;
const HomeRight = styled.div `
  float: right;
  width: 280px;
  margin-left: 15px;
  padding-top: 30px;
`;

render () {
    return (
        <HomeWrapper>
            <HomeLeft>
                left
            </HomeLeft>
            <HomeRight>
                right
            </HomeRight>
        </HomeWrapper>
    )
}
上面的代碼定義了三個組件，分別爲，這樣每個組件對應惟一的樣式，不在出現樣式污染的狀況。
若是在其餘組件中使用，以解構賦值的方式引入須要的樣式，而後當作標籤使用與上方使用相同HomeWrapper 、HomeLeft 、HomeRight

定義全局樣式

 

import { createGlobalStyle } from 'styled-components';

const GrobalStyle = 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;
    }
    
    @font-face {
      font-family: 'iconfont';  /* project id 897264 */
      src: url('//at.alicdn.com/t/font_897264_7ma62sn10m3.eot');
      src: url('//at.alicdn.com/t/font_897264_7ma62sn10m3.eot?#iefix') format('embedded-opentype'),
      url('//at.alicdn.com/t/font_897264_7ma62sn10m3.woff') format('woff'),
      url('//at.alicdn.com/t/font_897264_7ma62sn10m3.ttf') format('truetype'),
      url('//at.alicdn.com/t/font_897264_7ma62sn10m3.svg#iconfont') format('svg');
    }
    .iconfont {
      font-family:"iconfont" !important;
      font-size:16px;
      font-style:normal;
      -webkit-font-smoothing: antialiased;
      -moz-osx-font-smoothing: grayscale;
    }
    
    .clearfix:after {visibility: hidden;display: block;font-size: 0;content: ".";clear: both;height: 0;}
    .clearfix {zoom: 1;}
`;
上面的代碼GrobalStyle是全局樣式組件，只需在React組件的最外層引入便可。

 

引入圖片

須要圖片引入，若是像css同樣的引入方式，會報錯。正確的引入方式是import導入，再以變量的方式引入，以下：

 

import styled from 'styled-components';
import logPic from '../../statics/images/logo.png';

export const Logo = styled.div `
  position: absolute;
  top: 0;
  left: 0;
  width: 100px;
  height: 56px;
  background-image: url(${logPic});  
  background-size: contain;
`;
上面的代碼logPic是存放logo圖片地址的變量，只需使用${logPic}的方式引入便可
