html+css实现响应式卡片悬停效果

实现：

1. 定义标签，.kapian为最底层盒子，然后两个子盒子一个放图片，一个放文本：

<div class="kapian">
          <div class="tu">
             <img src="3.2.png">
          </div>
          <div class="wenben">
                <h2>The aurora borealis</h2>
                <p style="padding-bottom: 20px;">natural</p>
                <p>
                    Aurora Borealis is a colorful luminous phenomenon that appears over the high magnetic latitude region of the planet's North Pole. 
                    I love the aurora borealis. It's so beautiful.
                    </p>
          </div>
    </div>

2.先定义底层盒子的css基本样式，长宽等，就不详细说明了：

 .kapian{
            position: relative;
            width: 300px;
            height: 400px;
            border-radius: 3px;
            background-color: #fff;
            box-shadow: 2px 3px 3px rgb(139, 138, 138);
            overflow: hidden;
            cursor: pointer;
            transition: all 0.3s;
        }
        .kapian:hover{
            box-shadow: 2px 3px 10px rgb(36, 35, 35);
        }

:hover鼠标经过后盒子阴影变化。
transition: all 0.3s;过渡效果，阴影在0.3s内慢慢变化

3. 图片的基本样式，采用绝对定位：

.tu{
            position: absolute;
            top: 0;
            left: 0;
            width: 100%;
            height: 300px;
            overflow: hidden;
            
        }
        .tu img{
            width: 100%;
            height: 100%;
            transition: all 0.5s;
        }
        .kapian:hover .tu img{
            transform: scale(1.2);
            filter: blur(1px);
        }

:hover鼠标经过后图片变大，而且变模糊；
transform: scale(1.2);图片变大为1.2倍；
filter: blur(1px);图片变模糊；

4 .定义装文本这个盒子的基本样式，采用绝对定位：

.wenben{
            position: absolute;
            bottom: -200px;
            width: 100%;
            height: 300px;
            background-color: rgb(247, 242, 242);
            transition: 0.5s;
        }
        .kapian:hover .wenben{
            bottom: 0px;
        }

:hover鼠标经过后文本框绝对定位的bottom发生改变，使得呈现文本框向上展开的效果；

5 .文本框里字符的样式：

.wenben h2{
            color: rgb(21, 74, 172);
            line-height: 60px;
            text-align: center;

        }
        .wenben p{
            padding: 0 30px;
            font-family: 'fangsong';
            font-size: 16px;
            font-weight: bold;
            line-height: 20px;
            text-align: center;
        }
