I have been learning HTML/CSS/Bootstrap for around a week now and I'm just start a portfolio website as a sort of a test as to what I am able to do so far. Currently, I am having a problem creating the "about me" page responsive due to an image I have on that page.
Link to website is here http://moeminmamdouh.000webhostapp.com/aboutme.html
The desired outcome is to basically have everything centered, however, this is what shows up https://ibb.co/idEPVT
HERE IS THE CODEPEN LINK: https://codepen.io/muchkler/project/editor/AznjbN#
This is the HTML code:
<!DOCTYPE html>
<html>
<head> 
    <title> About Me </title>
    <link rel="stylesheet" type="text/css" href="aboutme.css">
    <link rel="stylesheet" type="text/css" href="bootstrap.css">

   <h1>HELLO.</h1>
    <h2>I'm Moemin Mamdouh</h2>
    <h3>graphic designer/ ui designer/ front-end developer</h3>
    <p>I provide entrepeneurs and startups with the kick they need to help start their business. A business is nothing without a brand, and a brand requires a stable and responsive website. I will be providing designs in both Adobe Photoshop and Adobe XD as the first step to any projects, afterwards, I move on to coding the actual website using HTML, CSS, and Bootstrap.  </p>
    <div class="imgbtns">

    }
}
@media only screen and (max-width: 992px){
