图像无法点击

Question

我有一本书的封面，我想要点击，但我无法获得链接作为图像。

    <div class="imagePage">
          <a href="../index.php">
            <img src="../images/covers/denmark.jpg" alt="Denmark">
          </a>
    </div>

    .imagePage {
           float: left;
           border-top: 30px;
           padding-right: 30px;
     }

请任何人都可以帮忙。我想知道我的媒体查询是否在干扰：

    /* xs */
img {
    width: 150px;
    height: auto;
}
/* sm */
@media (min-width: 768px) {
    img {
        width: 200px;
    }
}
/* md */
@media (min-width: 992px) {
    img {
        width: 350px;
    }
}
/* lg */
@media (min-width: 1200px) {
    img {
        width: 500px;
    }
}

编辑：我正在使用bootstrap。这是我的整个 CSS：

        padding-top: 30px;
        font-size: 16px;
        font-family: Candara, Calibri, Segoe, "Segoe UI", Optima, Arial,          sans-serif !important;

  }

您好我通过在 imagePage div中添加位置和z-index来解决此问题。请检查下面的造型，请告诉我。

.imagePage {
  float: left;
  border-top: 30px;
  padding-right: 30px;
  position: relative;
  z-index: 10;
}
