I have an image that i want to scale out when it has hovered.

code is written with react and css. What am i doing wrong?

Here is my gist which include style sheet as well as js code

react/js code

    import React from 'react';
import OwlCarousel from 'react-owl-carousel';
import 'owl.carousel/dist/assets/owl.carousel.css';
import 'owl.carousel/dist/assets/owl.theme.default.css';

import ScreenHeading from '../../utilities/ScreenHeading/ScreenHeading';
import ScrollService from '../../utilities/ScrollService';
import Animations from '../../utilities/Animations';
import './Certificates.css';
import clf from '../../img/Certs/clf.png';
import shape from '../../img/Certs/shape-bg.png';

export default function Certificate(props) {
  let fadeInScreenHandler = (screen) => {
    if (screen.fadeInScreen !== props.id) return;
    Animations.animations.fadeInScreen(props.id);
  };

  const fadeInSubscription =
    ScrollService.currentScreenFadeIn.subscribe(fadeInScreenHandler);

  const options = {
    loop: true,
    margin: 0,
    nav: true,
    animateIn: 'bounceInRight',
    animateOut: 'bounceOutRight',
    dots: true,
    autoplay: true,
    smartSpeed: 1000,
    responsive: {
      0: {
        items: 1,
      },
      768: {
        items: 1,
      },
      1000: {
        items: 3,
      },
    },
  };

  return (
    <div>
      <ScreenHeading
        title={'Certifications'}
        subHeading={'I love validating my skills'}
      />
      <section className="testimonial-section fade-in" id={props.id || ''}>
        <div className="container">
          <div className="row">
            <OwlCarousel
              className="owl-carousel"
              id="testimonial-carousel"
              {...options}
            >
              <div className="col-lg-12">
                <div className="testi-item">
                  <div className="testi-comment">
                    <p>
                      <i className="fa fa-quote-left" />
                      Learning about core aws services, shared responsibility
                      model and billing and pricing concepts was an eyeopener
                      for me as a cloud engineer.
                      <i className="fa fa-quote-right" />
                    </p>
                  </div>
                  <div className="client-info">
                    <img src={clf} alt="no internet connection"></img>
                    <h5>AWS CLF-01</h5>
                    <p></p>
                  </div>
                </div>
              </div>

              <div className="col-lg-12">
                <div className="testi-item">
                  <div className="testi-comment">
                    <p>
                      <i className="fa fa-quote-left" />
