help me figure out why it’s not working properly. I have a react.js component with html tags:

import React, { useEffect, useState, useRef } from "react";
import { useParams } from "react-router-dom";

export default function Subjectlist() {return (
    <>
      <section className="main-container">
        <div className="tab-nav-bar">
          <div className="tab-navigation">
            <i
              className="uil uil-angle-left left-btn"
            ></i>
            <i
              className="uil uil-angle-right right-btn"></i>
            <ul className="tab-nav-list" ref={tabNavListRef}>
              {subjects.map((subject) => (
                <li
                  className="tab-nav-item tab-nav-item-active"
                  key={subject.id}
                >
                  {subject.subjectName}
                </li>
              ))}
            </ul>
          </div>
        </div>

        <div className="tab-subject-content">
          <div className="tab-subject _active-tab">
            <div className="left-column">
              <div className="tab-row">
                <div className="img-card">
                  {subjects.map((subject) => (
                    <img
                      className="tab-img"
                      src={`${subject.img}`}
                      alt={`${subject.subjectName}`}

                  ))}
                </div>

                <div className="tab-right-column">
                  <div className="tab-info">
                    <ion-icon

                      name="arrow-redo-outline"
                    ></ion-icon>
                    <ion-icon

          </div>
        </div>

I wrote styles for them:

  }
  .tab-subject .img-card {
    width: auto;
    max-width: 600px;
  }
}

but the page does not display the img correctly. It either shows two pictures at once, or one picture and two incomplete ones on the sides: I have attached screenshots

I searched for answers on the Internet but couldn’t find them.
