In the program, li is an element in the HTML markup language and is used to create lists. li represents list item, which is a child element of ul (unordered list) or ol (ordered list). The purpose of the li tag is to define each item in the list.

In HTML, the li element is usually used in conjunction with the ul or ol element to create an ordered or unordered list. Unordered lists use ul elements, and list items are represented by li elements, while ordered lists use ol elements, which are also represented by li elements. The li element can contain text, images, and other HTML elements. Within a ul or ol element, li elements are presented sequentially to form a list of items.

For example, the following code demonstrates an unordered list containing three items:

```
<ul>
  <li>苹果</li>
  <li>香蕉</li>
  <li>橙子</li>
</ul>
```

This code will be displayed in the browser as:

- 苹果
- 香蕉
- 橙子

Each Each li element is surrounded by a ul element, indicating that it is an unordered list. Each li element represents an item, and the text content is apples, bananas, and oranges.

Similarly, the following code demonstrates an ordered list containing three items:

```
<ol>
  <li>第一步</li>
  <li>第二步</li>
  <li>第三步</li>
</ol>
```

This code will be displayed in the browser as:

1. 第一步
2. 第二步
3. 第三步

Each li element is surrounded by ol elements, indicating that it is an ordered list. Each li element represents an item, and the number indicates the order of the items.

In summary, the li element represents list items in HTML in the program and is used to create ordered or unordered lists. Through the combination of ul or ol elements, the li element can arrange items in order or disorder, making the list clearer and easier to read.
