1.实现效果
2.实现步骤
- 定义一个宽高为300px的父容器
<div class="box"></box>
.box {
position: relative;
width: 300px;
height: 300px;
}
- 父容器中添加一张图片，与父容器大小一致
<div class="box">
+ <img src="https://i.postimg.cc/GhXrMDN0/card.jpg" alt="图片" />
</div>
.box img {
width: 100%;
height: 100%;
}
- 为父容器添加伪元素，宽高与父元素一致，背景色为50%的白色，基于父容器left为0，top为0，默认opacity设置为0，即不可见，并设置0.4s的transition过渡
.box:before {
content: "";
background: rgba(255, 255, 255, 0.5);
width: 100%;
height: 100%;
position: absolute;
z-index: 1;
top: 0;
left: 0;
opacity: 0;
transition: all 0.4s ease;
}
- 父容器添加hover事件，当hover时候，为图片添加filter滤镜，设置透明度以及0.4s的transition过渡
.box img {
+ transition: all 0.4s;
}
.box:hover img {
opacity: 0.8;
filter: brightness(1.5);
}
- 父容器添加hover事件，当hover时候，修改伪元素的高度为70%，设置border-radius圆角，将opacity改为1
.box:hover:before {
height: 70%;
border-radius: 0 0 150px 150px;
box-shadow: 0 0 20px #000;
opacity: 1;
}
- 父容器添加圆角区域展示内容，方便调试，可以将hover状态选中
- 圆角区域添加两行文字（可根据需求进行修改），默认opacity设置为0，即不可见，并设置1s的transition过渡
<div class="box">
+ <div class="box-content">
+ <p>苏苏小苏苏</p>
+ <p>web 前端</p>
+ </div>
</div>
.box .box-content {
color: #333;
text-align: center;
width: 100%;
padding: 0 30px;
transform: translateX(-50%);
position: absolute;
top: 25%;
left: 50%;
z-index: 1;
opacity: 0;
transition: all 0.4s ease;
}
- 父容器添加hover事件，当hover时候，圆角区域将opacity改为1
.box:hover .box-content {
opacity: 1;
}
- 父容器添加底部图标，两个图标flex横向布局，基于父容器absolute定位，水平居中，距离底部10px
<div class="box">
+ <div class="box-icon">
+ <div class="icon-item"><span class="iconfont"></span></div>
+ <div class="icon-item"><span class="iconfont"></span></div>
+ </div>
</div>
.box .box-icon {
position: absolute;
left: 50%;
transform: translateX(-50%);
bottom: 10px;
display: flex;
align-items: center;
}
.box .icon-item {
margin: 0 2px;
background: rgba(255, 255, 255, 0.5);
height: 35px;
width: 35px;
text-align: center;
line-height: 31px;
border: 2px solid #fff;
cursor: pointer;
}
- 设置底部图标进行x方向的偏移，两个图标进行相反方向的偏移，偏移出父容器可见区域即可，并设置0.4s的transition过渡
.box .icon-item{
+ transition: all 0.4s;
}
.box .icon-item:nth-child(1) {
transform: translateX(-200px);
}
.box .icon-item:nth-child(2) {
transform: translateX(200px);
}
- 父容器添加hover事件，当hover时候，设置底部图标进行x方向偏移量为0
- 父容器设置overflow: hidden，不展示底部图标
.box {
+ overflow: hidden;
}
- 为底部图标添加hover事件，当hover时候，设置圆角，就完成了啦~
.box .icon-item:hover {
background-color: #fff;
border-radius: 50%;
}
