Footer not enlarging/expanding

I created a website, and I want to expand my footer because right now it looks like this:

It should cover the whole website and I tried increasing the width, but that did not work.

This is the HTML/CSS of the footer:

#footer {
  background: #f7f8f9;
  color: #45505b;
  font-size: 14px;
  text-align: center;
  padding: 30px 0;
}

#footer h3 {
  font-size: 36px;
  font-weight: 700;
  position: relative;
  font-family: "Poppins", sans-serif;
  padding: 0;
  margin: 0 0 15px 0;
}

#footer p {
  font-size: 15;
  font-style: italic;
  padding: 0;
  margin: 0 0 40px 0;
}

#footer .social-links {
  margin: 0 0 40px 0;
}

#footer .social-links a {
  font-size: 18px;
  display: inline-block;
  background: #0563bb;
  color: #fff;
  line-height: 1;
  padding: 8px 0;
  margin-right: 4px;
  border-radius: 50%;
  text-align: center;
  width: 36px;
  height: 36px;
  transition: 0.3s;
}

#footer .social-links a:hover {
  background: #0678e3;
  color: #fff;
  text-decoration: none;
}

#footer .copyright {
  margin: 0 0 5px 0;
}

#footer .credits {
  font-size: 13px;
}

 <footer id="footer">
    <div class="container">
      <h3>My name</h3>
      <p></p>
      <div class="social-links">
        <a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/in/kaustubh-prabhakar/" class="linkedin"><i class="bx bxl-linkedin"></i></a>
        <a target="_blank" rel="noopener noreferrer" href=href="https://github.com/SantaKaus" class="github"><i class="bx bxl-github"></i></a>
        <a target="_blank" rel="noopener noreferrer" href="https://www.instagram.com/santa_kaus/" class="instagram"><i class="bx bxl-instagram"></i></a>
      </div>
      <div class="copyright">
        &copy; <strong><span>my name</span></strong> 2021
      </div>
    </div>
  </footer><!-- End Footer -->

I got the whole footer code from another source, and I tried copying and pasting the code exactly it is, but for some reason, I cannot get it to expand more idk why. Can you guys please help?

When you run the above code, it outputs fine but on my end, I am getting the output in the picture I sent above.

Is the problem occurring because I may be overriding other CSS elements with it? I have multiple CSS files and I tried changing the names of the footer CSS class but it still didn’t work.

You shared your code in your previous question. You have body with display grid property.

• First, seems you don’t use grid at all, you can just delete this property.
• Also you can set place-items to stretch to achieve the same effect.
• Seems just setting width of the footer to 100% works fine too
