Question

Write an HTML code segment that uses a list to display the names of your grandparents and your parents. The list should be organized to show the relationships clearly.

Short answer

• Grandparent 1
  • Parent 1
  • Parent 2
• Grandparent 2
  • Parent 3
  • Parent 4

Step-by-step solution

- Define the HTML Structure

Start by setting up the basic HTML structure with the ` `, ``, ``, and `` tags.

- Create the Unordered List for Grandparents

Within the `` tag, create an unordered list (`

`) to list your grandparents' names. Inside the `
`, use `
• ` tags to include each grandparent's name.

- Nest Parents List Inside Grandparents List

For each grandparent, nest another unordered list `

` inside the corresponding `
• ` to list their children (your parents). Use `
• ` tags within this nested `
  ` to include each parent's name.

- Close All Tags

Ensure all opened HTML tags are properly closed: the nested `

`, main list `
`, and the overall ``, `` structure. This will finalize the HTML structure.

Key concepts

HTML basics

HTML, or HyperText Markup Language, is the standard language used to create web pages. It uses tags to describe the structure and content of a webpage. Each HTML document starts with a `` declaration, which helps the browser understand how to interpret the document.

Basic tags to know include ``, which wraps the entire HTML document; ``, which contains meta-information about the document like its title and links to stylesheets; and ``, which contains the actual content displayed by the browser.
Elements within an HTML document are nested inside these main tags. Each element is defined by its opening tag (``) and closing tag (``), encapsulating the content within them. This structure allows for the easy organization and parsing of content by web browsers.

Unordered list

An unordered list in HTML is used to display a list of items in no particular order. It is defined using the `

` tag with each item in the list represented by an `
• ` (list item) tag.
  
  Here’s a simple example of an unordered list:
  `
  `
  `
  • Item 1
  `
  `
  • Item 2
  `
  `
  • Item 3
  `
  `
  `
  
  This will create a bulleted list with three items. Unordered lists are useful for grouping related items together. They can be styled in various ways using CSS, including changing the bullet style, adding padding, or adjusting the list's alignment.
  Understanding unordered lists is crucial for organizing content in a clear and readable manner, especially when the order of items is not important.

Nested lists

Nested lists are lists within lists, which allow for a hierarchical structure. In HTML, you can nest an unordered list (`

`) inside another unordered list by placing it within an `
• ` element.
  
  For example, to display your grandparents and their children (your parents), you could structure your HTML as follows:
  `
  `
  `
  • Grandparent 1`
    `
    `
    `
    • Parent 1
    `
    `
    • Parent 2
    `
    `
    `
    `
  `
  `
  • Grandparent 2`
    `
    `
    `
    • Parent 3
    `
    `
    • Parent 4
    `
    `
    `
    `
  `
  `
  `
  This example nests `
  ` tags within `
  • ` elements, creating a clear hierarchical relationship between grandparents and parents.
    Nested lists are powerful for creating multi-level menus and organizing complex data structures on web pages. They help convey relationships between items and enhance user navigation.
