Where is this excess horizontal space coming from?

Question

I am building a React.js website app for a university project which uses Reactstrap as well as my custom CSS. I have just noticed that I have horizontal scrolling but I cannot figure out where it is coming from.

You can see the extra space on the image, it seems to be something to do with the navbar but I just have no idea why and have played around with the CSS a lot. I must be completely missing something?

Code for the Navbar.js component:

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;

I can provide the code for the other components on the page if necessary.

Answer 1

SOLVED

It was an issue with one of the other components.

I used dev tools to manually go through and delete elements to find out which one caused the horizontal scroll. I then edited the CSS for that component by adding

max-width: 100%;

This was a very helpful tutorial on how to do this: https://css-tricks.com/findingfixing-unintended-body-overflow/

Answer 2

Need to see css for .custom-nav-bg and .fixed-top

Answer 3

I think the body has some padding or margin...

add this class... I hope it will work:

body {
  padding: 0;
  margin: 0;
}
