效果图:

总结:

  1. Margin在绝对定位 position:fixed;下是无效的

  2. justify-content 用于设置或检索弹性盒子元素在主轴(横轴)方向上的对齐方式。默认值:flex-start

  3. a标签里面的字体颜色必须通过a标签实现,不能直接继承父集的文本样式,否则无效。

  4. 问题:banner图被固定的导航盖住了一部分?

    解决方案:在  .banner里面加一个padding-top:42px;

  5. 弹性盒子展示: display:flex;

    弹性盒子是给子元素的效果,所以给了 <ul>

    均分盒子内空间,是让 <li>均分

  6. 顶部和底部:

    首先考虑定位:  position:fixed; 一般是固定的,方便导航

    然后考虑到浏览器边框的举例,top/buttom   left :0

    然后考虑 宽高 的值,自适应 宽度设置百分比一般 100% 高具体看情况设置多少px

    然后考虑最大最小宽度,手机啥的合适,

    导航中间部分要调整居中, left:50%;  transform:translateX(-50%)
