樣式化的組件不會重新樣式化組件

Question

我在使用styled-components對Gats中的組件進行“重新樣式化”時遇到了一些麻煩

"styled-components": "^3.3.0" "gatsby-plugin-styled-components": "^2.0.11"

我的gatsby-config有gatsby-plugin-styled-components ， gatsby-config ，當我再次通過styled()放置自定義組件時，樣式可以在所有欄上使用：

我在這里有一個側邊欄

import React, { Component } from "react";
import styled from "styled-components";

class Aside extends Component {
  render() {
    return (
      <Sidebar>
        <List>
          <Item>Pintrest 1</Item>
          <Item>Pintrest 2</Item>
          <Item>Pintrest 3</Item>
        </List>
      </Sidebar>
    );
  }
}

const Sidebar = styled.div`
  position: absolute;
  width: 200px;
  left: calc(100% + 20px);

  @media (max-width: 1200px) {
    position: relative;
    width: 100%;
    left: 0;
    top: 0;
  }
`;

在一頁上，我希望樣式為top: 0; 所以我通過了

const SideBar = styled(Aside)`
  top: 0;
`;

。

import React from 'react'
import Helmet from 'react-helmet'
import Link from 'gatsby-link'
import get from 'lodash/get'
import styled from "styled-components";

import Bio from '../components/Bio'
import Aside from '../components/Aside';

class BlogPostTemplate extends React.Component {
  render() {
    const post = this.props.data.markdownRemark
    const siteTitle = get(this.props, 'data.site.siteMetadata.title')
    const { previous, next } = this.props.pathContext

    return (
      <div>
        <Helmet title={`${post.frontmatter.title} | ${siteTitle}`} />
        <Bio />
        <Post>
          <h1>{post.frontmatter.title}</h1>
          <SideBar/>
        </Post>
      </div>
    )
  }
}

甚至嘗試過

const aside = ({className}) => <Aside className={className}/>;

const SideBar = styled(aside)`
  top: 0;
`;

如所示

但是它不起作用並且沒有更改樣式，這是lib gatsby-plugin-styled-components或styled-components的限制，還是我誤解了styled-components的目的

要像您鏈接的示例中那樣完成此操作，您將需要將className屬性傳遞給孩子，如下所示：

class Aside extends Component {
  render() {
    return (
      <Sidebar className={this.props.className}>
        <List>
          <Item>Pintrest 1</Item>
          <Item>Pintrest 2</Item>
          <Item>Pintrest 3</Item>
        </List>
      </Sidebar>
    );
  }
}
