英文:
HTML Navbar flipping when inserting the float:right property
问题
我有一个HTML导航栏，并且我想把导航栏中的所有元素移到右边。下面，我尝试使用float: right;来实现这个目标。虽然这确实将所有内容移到了右边，但它翻转了整个导航栏（原本在左边的元素现在在右边，反之亦然）。我已经附上了代码。为什么会这样？
<!DOCTYPE html>
<html>
<head>
<style>
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-image: linear-gradient(rgb(83, 152, 42), rgb(51, 110, 14));
}
li {
float: right;
border-right: 1px solid #000;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
li a,
.dropbtn {
display: inline-block;

text-align: center;
padding: 14px 16px;
text-decoration: none;
}
li.dropdown {

I have an HTML Navbar, and I want to shift all the elements in the navbar to the right. Below, I have attempted to use float: right; to do so. Although this does move everything to the right, it flips the entire navbar (so that elements that were originally in the left are now on the right, and vice versa). I have attached the code below. Why is it doing this?

我已经添加了一些样式：display: block, width: 100% 和 text-align: right，它起作用了（重要的是使链接充满整个宽度，以改善用户体验）。
但我建议使用 flex 布局来实现这种布局，并采用移动优先的方法，这意味着您的媒体查询应该是以 min-width 定义的，从小屏幕到大屏幕进行设计。

祝你好运！
英文:
I have added some display: block, width: 100% and text-align: right and it works (important to make the link full width for improve the user experience)
But, I would recommend to use flex layout to achieve this kind of layouts, and use a mobile first apprach, that meands that your media queryes are defined with min-width to design from small to large screens

Good luck!

你可以在父级 ul 上使用 display: flex 和 justify-content: flex-end 来使当前顺序对齐到末尾。
ul {
display: flex;
justify-content: flex-end;
}
示例：
<!DOCTYPE html>
<html>
<head>
<style>
ul {
display: flex;
justify-content: flex-end;
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-image: linear-gradient(rgb(83, 152, 42), rgb(51, 110, 14));
}
li {
/* float: right; */
border-right: 1px solid #000;
}
li a {
display: block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
li a,
.dropbtn {
display: inline-block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
li.dropdown {
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: rgb(95, 161, 6);
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
z-index: 1;
}
.dropdown-content a {
color: white;
padding: 12px 16px;
text-decoration: none;
display: block;
text-align: left;
}
.dropdown-content a:hover {
background-color: #f1f1f1;
}
.dropdown:hover .dropdown-content {
display: block;
}
li a:hover:not(.active) {
background-color: rgb(0, 90, 0);
}
.active {
background-color: #04AA6D;
}
@media screen and (max-width: 600px) {
ul li {
border-right: none;

ul li {
float: none;

英文:
You can use display display: flex and justify-content: flex-end on parent ul to align to the end on current order.
ul {
display: flex;
justify-content: flex-end;
}
Example:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-html -->
<!DOCTYPE html>

ul {
display: flex;
justify-content: flex-end;

margin: 0;
padding: 0;
overflow: hidden;
background-image: linear-gradient(rgb(83, 152, 42), rgb(51, 110, 14));
}
li {
/* float: right; */
border-right: 1px solid #000;
}
li a {
display: block;

text-decoration: none;
}
li a,
.dropbtn {
display: inline-block;

text-align: center;
padding: 14px 16px;
text-decoration: none;

li.dropdown {

.dropdown-content {
