我想要一些翻转盒子。鼠标悬停时,图像会翻转并显示文本。这有效,但没有响应(第二行框结束前一行)。问题是.f_contenedor的高度,我希望响应,所以我在用“padding-top:56%”这个属性。

如何确保“f_contendor”的高度与.face相同?

这里有一个例子:http://bregna.org/flip.html

这是片段。是相同的代码,只是背景不同。

        .f_contenedor:hover .f_card {
            transform: rotateY(180deg);
            box-shadow: -5px 5px 5px #aaa;
        }

        .f_contenedor {
            position: relative;
            padding: 10px;
            width: 50%;
            height: auto;
            z-index: 1;
            float: left;
            perspective: 1000;
            box-sizing:border-box;;
        }

        .f_card {
            width: 100%;
            height: 100%;
            transform-style: preserve-3d;
            transition: all .3s linear;

        }

        @media (min-width: 768px) {
            .f_contenedor {
                width: 50%;
            }
        }

        @media (min-width: 992px) {
            .f_contenedor {
                width: 30%;
            }

        }

        .shadow {
            -moz-box-shadow: 5px 5px 5px rgba(68, 68, 68, 0.6);
            -webkit-box-shadow: 5px 5px 5px rgba(68, 68, 68, 0.6);
            box-shadow: 5px 5px 5px rgba(68, 68, 68, 0.6);
        }

        .face {
            background-size: cover;
            background-repeat: no-repeat;
        }

        .face {
            position: absolute;

            width: 100%;
            height: 0;
            padding-top: 56%;
            backface-visibility: hidden;

        }

        .face.back {
            display: block;
            transform: rotateY(180deg);
            box-sizing: border-box;
            height: 100%;
            color: white;
            text-align: center;
            background-color: #aaa;
        }

        .face.back span {
            margin-top: -56%;
            padding: 12px;
            display: block;
        }

可以稍微调整CSS,以便.back face被完全定位为绝对值,并对齐到父级的顶部。此外,还需要调整.face相对定位。

一些相关的东西:

.face {
  /*   position: absolute; Remove this */ 
  position:relative; /* Position the face relatively by default */

  width: 100%;
  height: 0;
  padding-top: 56%;
  backface-visibility: hidden;

}

.face.back {
  position:absolute; /* For back faces, these should be positioned with absolute */
  top:0; /* Align back faces with the top of the parent */
  display: block;
  transform: rotateY(180deg);
  box-sizing: border-box;
  height: 100%;
  color: white;
  text-align: center;
  background-color: #aaa;
}
