html - 如何使导航按钮移动响应并按顺序折叠？

Question

几个小时以来，我一直在尝试使用不同的方法让我的导航按钮移动响应并以指定的垂直顺序折叠。一旦屏幕尺寸缩小(缩小到 500 像素左右)，我希望导航按钮折叠在两个 Logo 下方的垂直列中。如何修复我的代码以实现此目的？

CSS 就是自然顺序、自然位置、自然样式......我的意思是你的代码不自然，你可以在这里看到:

.navigation li {
  display: inline-block;

}

.navigation a {
  padding: 12px 20px;
}

我想专注于这些属性，因为我们在这里说:

You <a> element that are inside this man -> <li> (<li id="NAV-ONE"><a
href="#">LOG IN</a></li>), yes you! You will be bigger even if you're inside him!

嗯，在现实生活中，我们不能把更大的东西放在更小的空间里。在现实生活和 CSS 中发生的事情是:小事变成大事。

因此，如果我们进行此更改:

.navigation li {
  display: inline-block;
  padding: 12px 20px;
}

.navigation a {
  /* We changed who is bigger than who */
}

它需要一个自然顺序(因为现在 .navigation a 所在的空间比他大)。最终代码是这样的(当你使用电话时这将换行):

.navigation li {
  display: inline-block;
  padding: 12px 20px;
  background: linear-gradient(#49708f, #293f50);
  background: #395870;
  border-right: 1px solid rgba(0, 0, 0, .3);
}

.navigation a {
  color: #fff;
  text-decoration: none;
}

我在玩的时候发现了这种很酷的屏幕小的包裹方式，我觉得很酷:

@media all and (max-width: 500px){
    ul.navigation{
        display: flex;
        flex-wrap: wrap;
        justify-content: flex-end;
    }
}

此外，请记住，当您想要进行响应式设计时，您需要将 meta:viewport 放入 html 的头部:

<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
