html - 图像链接

Question

我这里有个问题。我想将文本(链接)放在图像上。我知道position:absolute、position:relative和 z-index，但不起作用:(

HTML:

<section id="container>
    <div class="wrap">
        <ul>
                <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
                    <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
            <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
                    <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
            <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
                    <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
            <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
                    <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
            <li><a href="#"><img src="img/hello.jpg" alt="">Text</a></li>
        </ul>
    </div>
</section>

CSS:

ul {
  margin: 15px auto;
  overflow: hidden;
  padding-bottom: 10px;
  border-bottom: 1px solid #ccc;
  width: 95%;
  text-align: center;
}

li {
  display: inline-block;
  width: 33%;
  text-align: center;
  background-color: #282828;
}

li:hover img {
  opacity: 0.1;
}

img {
  max-width: 100%;
  display: block;
}
