手抄:

将中间导航菜单区的代码手抄至少一遍, 并给每一行代码加上注释

html代码:
<!--导航-->
<nav>
    <ul>
        <li>
            <a href="">
                <img src="images/html.png" alt="">

                <span>直播</span>
            </a>
        </li>
    </ul>
</nav>
css代码:
/*主导航基本样式*/
nav{
    /*背景*/
    background-color: #fff;
    /*转为弹性容器,主轴改为垂直方向*/
    display: flex;
    flex-flow: column nowrap;
}

/*图片大小*/
nav img{
    width: 45px;
    height: 49px;
}

/*每行导航都是个容器*/
nav>ul{
    display: flex;

}

/*每个元素进行空间平均分--增长因子都是1*/
nav>ul>li{
    flex: 1;
}

/*图片文本组件统一设置*/
nav>ul>li>a{
    display: flex;
    flex-flow: column nowrap;
    /*交叉轴上居中显示*/
    align-items: center;

    margin: 10px;
}

nav>ul>li>a>span{
    margin-top: 5px;
}

手抄:

总结

对于相同格式的html,在css中可以直接通过选择器来统一设置样式(此处我没有使用,因为生疏怕乱掉)
