HTML lists are used to group related pieces of information. There are three types of lists:


  1. bulleted list - <ul> - each element of the list <li> is marked with a marker,
  2. numbered list - <ol> - each element of the list <li> is marked with a number,


Each list is a container within which list elements or term-definition pairs are located. List items behave like block items, located under each other and occupying the entire width of the container block. Each list item has an additional block located on the side, which is not involved in the layout.
A bulleted list is an unordered list (from the English Unordered List). Created using the paired <ul> </ul> tag. A marker, for example, a filled circle, acts as a marker for a list item.
A numbered list is created using the paired <ol> </ol> tag. Each list item is also created using the <li> element. The browser automatically numbers the elements in order, and if you delete one or more elements of this list, the remaining numbers will be automatically recounted.
