first of all as aerial301 said you are not targeting the img tag but the div tag.
secondly you should change the html from <div class="img-container"> to <div id="img-container"> you were targeting the div with class img-container no an id
const reviews = [ { id: 1, name: "susan smith", job: "web developer", img: "https://res.cloudinary.com/diqqf3eq2/image/upload/v1586883334/person-1_rfzshl.jpg", text: "I'm baby meggings twee health goth +1.
