响应式图像悬停标题

Question

我遇到的问题是悬停标题.caption-text和重叠.blur是固定的宽度和高度，而图像是响应的。

有关如何修改此代码以使叠加层和标题适合图像宽度和高度的任何建议吗？

.caption-style-4 li {

  padding: 0px;
  position: relative;
  overflow: hidden;
}
.caption-style-4 li:hover .caption {
  opacity: 1;
}
.caption-style-4 li:hover img {
  opacity: 1;
  transform: scale(1.15, 1.15);

只需更新您的CSS

.caption-style-4 .caption-text {
    z-index: 10;
    color: #fff;
    position: absolute;
    width: 100%;
    height: 95px;
    text-align: center;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
}
.caption-style-4 .blur {
    background-color: rgba(0,0,0,0.65);
    height: 100%;
    width: 100%;
    z-index: 5;
    position: absolute;
}
.caption-style-4 .caption {
    cursor: pointer;
    position: absolute;
    opacity: 0;
    -webkit-transition: all 0.45s ease-in-out;
    -moz-transition: all 0.45s ease-in-out;
    -o-transition: all 0.45s ease-in-out;
    -ms-transition: all 0.45s ease-in-out;
    transition: all 0.45s ease-in-out;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
    width: 100%;
    height: 100%;
}

让我知道它是否仍无效。

您可以包含jquery.js并计算图像的宽度和高度。 同时添加到css .singlePillar .caption {top:0px;} 例： https://jsfiddle.net/hc2tr7s3/
