Answer 1

试试这样写

.testimonial-section:hover .client-info img {
  transform: scale3D(1.5,1.5,1.5);
}

或

.testimonial-section .client-info img:hover {
  transform: scale3D(1.5,1.5,1.5);
}

Answer 2

在这种情况下，transform: scale(1.5); 应该可以工作。这是一个工作示例（不是您的代码）

.image-box {
  width: 100px;
  height: 100px;
  text-align: center;
  border: 1px solid gray;
  overflow: hidden; 
}

.image-box img {
  width: 100px;
  height: 100px;
  transition: 300ms;
}

.image-box img:hover {
  transform: scale(1.5);
}

  <div class="image-box">
    <img src="https://static-cdn.jtvnw.net/emoticons/v2/25/default/dark/1.0" alt="">
  </div>

使用您的 HTML/CSS

.client-info img {
  height: 70px;
  width: 70px;
  border: 2px solid transparent;
  border-color: black;
  left: 30px;
  top: -4px;
  border-radius: 50%;
  position: relative;
}

.client-info h5 {
  font-size: 20px;
  font-weight: 600;
  line-height: 26px;
  margin: 0 0 2px 10px;
  position: absolute;
}

.client-info:hover img {
  transform: scale3D(1.5, 1.5, 1.5);
}
  

<div class="client-info">
    <img src="https://static-cdn.jtvnw.net/emoticons/v2/25/default/dark/1.0" alt="no internet connection"></img>
    <h5>AWS CLF-01</h5>
    <p></p>
  </div>
