In HTML, there are three types of lists: ordered, unordered, and descriptive.

Ordered List and Unordered List

An ordered list is a list of items numbered, whereas an unordered list is a list of items marked with bullet points.

Here is an example of an unordered list:

This would create a bullet-pointed list with the items 'First item', 'Second item', and 'Third item'.

Both the <ol> and <ul> elements can be used with the type attribute to specify the numbering or bullet point style.

For example, you could use the type attribute to create a list with lowercase letters instead of numbers, like this:

The <li> element can be used with the value attribute to specify the numbering or bullet point style for a specific item in the list.

Descriptive list

A description or definition list lists terms and their corresponding descriptions.

The <dl> element is used to define the description list, and the <dt> and <dd> elements are used to determine the terms and descriptions, respectively.

Here is an example of a description list with multiple descriptions for a single term:
