CSS属性探秘系列(三):line-height
可以使用flex布局来实现秒表和按钮的居中和底部排列。具体的样式代码如下:
```
#box {
display: flex;
justify-content: center;
align-items: center;
flex-direction: column;
width: 100%;
height: 100%;
background-color: black;
position: relative;
}
#timer {
width: 300px;
height: 300px;
border-radius: 50%;
border: 5px dashed #2fa4e4;
position: relative;
color: aliceblue;
}
#buttons {
display: flex;
justify-content: center;
align-items: flex-end;
position: absolute;
bottom: 0;
margin-bottom: 20px;
}
#buttons button {
background-color: orange;
color: black;
font-size: 16px;
padding: 10px 20px;
margin: 0 10px;
border-radius: 5px;
border: none;
cursor: pointer;
}
```
需要注意的是,需要给父容器#box设置flex布局,并设置justify-content和align-items属性为center,使其水平垂直居中。同时,需要给#buttons设置position: absolute和bottom: 0属性,使其位于父容器的底部。
