html - 响应式图像悬停标题

Question

我面临的问题是悬停标题 .caption-text 和叠加层 .blur 的宽度和高度是固定的，而图像是响应式的。

关于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？

.caption-style-4 {
  list-style-type: none;
  margin: 0px;
  padding: 0px;
}
.caption-style-4 li {
  float: left;
  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);
  -webkit-transform: scale(1.15, 1.15);
  -moz-transform: scale(1.15, 1.15);
  -ms-transform: scale(1.15, 1.15);
  -o-transform: scale(1.15, 1.15);
}
.caption-style-4 img {
  margin: 0px;
  padding: 0px;
  float: left;
  z-index: 4;
}
.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;
}
.caption-style-4 img {
  -webkit-transition: all 0.25s ease-in-out;
  -moz-transition: all 0.25s ease-in-out;
  -o-transition: all 0.25s ease-in-out;
  -ms-transition: all 0.25s ease-in-out;
  transition: all 0.25s ease-in-out;
}
.caption-style-4 .blur {
  background-color: rgba(0, 0, 0, 0.65);
  height: 300px;
  width: 400px;
  z-index: 5;
  position: absolute;
}
.caption-style-4 .caption-text h1 {
  text-transform: uppercase;
  font-size: 24px;
}
.caption-style-4 .caption-text {
  z-index: 10;
  color: #fff;
  position: absolute;
  width: 400px;
  height: 300px;
  text-align: center;
  top: 100px;
}

<div class="container-a4">
  <ul class="caption-style-4">
    <li>
      <img src="http://lorempixel.com/output/abstract-q-c-600-480-1.jpg" alt="">
      <div class="caption">
        <div class="blur"></div>
        <div class="caption-text">
          <h1>Amazing Caption</h1>
          <p>Whatever It Is - Always Awesome</p>
        </div>
      </div>
    </li>
  </ul </div>

只需更新你的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%;
}
