这个多余的水平空间是从哪里来的？

我正在为一个使用Reactstrap和我的自定义CSS的大学项目构建React.js网站应用程序。我刚刚注意到我可以进行水平滚动，但是我无法弄清楚它的来源。

您可以看到图像上的多余空间，这似乎与导航栏有关，但我不知道为什么，并且已经使用了很多CSS。我一定会完全想念什么吗？

Navbar.js组件的代码：

import Navbar from 'react-bootstrap/Navbar';
import Nav from 'react-bootstrap/Nav';
import Button from 'react-bootstrap/Button';
import {
  Link
} from 'react-router-dom';

class NavBar extends React.Component {
  render() {
    return (
      <Navbar expand="md" className="custom-nav-bg fixed-top">
        <Navbar.Brand expand="lg" href="#home">
        <Link to="/home"><img className="custom-nav-logo"
            src="logohero.png"
            alt="StatHero Logo"
            width="105px"
            height="50px"
          /></Link>
        </Navbar.Brand>
        <Nav className="collapse navbar-collapse mr-auto justify-content-end">

          <Nav.Link className="custom-nav-text" href="#about">
          <Link to="/about">ABOUT</Link>
          </Nav.Link>

          <Nav.Link className="custom-nav-text" href="#stats">
          <Link to="/stats">STATS</Link>
          </Nav.Link>

          <Nav.Link className="custom-nav-text" href="#faqs">
          <Link to="/faq">FAQS</Link>
          </Nav.Link>

          <Nav.Link className="custom-nav-text" href="#contact">
          <Link to="/contact">CONTACT</Link>
          </Nav.Link>

          <Nav.Link className="custom-nav-text" href="#signup">
            <Button className="custom-nav-button">SIGN UP</Button>
          </Nav.Link>

          <Nav.Link className="custom-nav-text" href="#login">
          LOGIN
          </Nav.Link>

        </Nav>

    </Navbar>
    )
  }
}
export default NavBar;
