导航栏获得水平布局

Question

我有以下用于 React 应用程序中导航栏的代码。当浏览器 window 很宽时，导航栏内容看起来不错，但是一旦我超过 navbar-expand-lg 截止点，图标就会一个接一个地垂直对齐。我该如何防止呢？（见下面的代码截图）

import React, {Component} from 'react';
import {
  Badge,
  Nav,
  Navbar,
  NavbarBrand,
  NavbarToggler,
  NavItem,
  NavLink,
} from 'reactstrap';
import FontAwesome from '@fortawesome/react-fontawesome';

class Header extends Component {

  constructor(props) {
    super(props);
  }

  render() {
    return (
      <Navbar dark color="dark" expand="lg" className="w-100 p-1">
        <NavbarToggler className="d-flex"/>
        <NavbarBrand className="ml-3" href="/">Logo</NavbarBrand>
        <Nav className="d-flex ml-auto" horizontal="end" navbar>
          <NavItem>
            <NavLink href="#">
              <FontAwesome icon={["fas","bell"]} className="text-light" size="lg" />
              <Badge pill color="danger">5</Badge>
            </NavLink>
          </NavItem>
          <NavItem>
            <NavLink href="#">
              <FontAwesome icon={["fas","clipboard"]} className="text-light" size="lg" />
              <Badge pill color="warning">5</Badge>
            </NavLink>
          </NavItem>
          <NavItem>
            <NavLink href="#">
              <i className="icon-location-pin"></i>
              <Badge pill color="info">5</Badge>
            </NavLink>
          </NavItem>
        </Nav>
        <NavbarToggler className="d-flex ml-3"/>
      </Navbar>
    );
  }
}

export default Header;

Answer 1

只需将 navbar-expand-lg 替换为 navbar-expand

Answer 2

要实现您想要的效果，您需要使用 flex-row class 将通常的弹性列变成弹性行。

这是您的导航栏的完整工作代码，包括两个汉堡菜单（我在 lg 屏幕上用 d-lg-none class 隐藏了正确的菜单项）：

图标右侧的内边距已调整为右内边距 classes pr-3 pr-lg-0，即 lg 屏幕上的零或默认内边距以及 3 个单位的右内边距较小的屏幕。

另请注意 order-lg-last class 如何在 lg 屏幕及更高屏幕上切换内容。
