All list items (`li`) must have `ul` or `ol` parent elements.

To be considered valid, a list must have both parent and child entries. Element parents may consist of either a set of `ul` or `ol` tags. Within these tags, child elements must be declared using the `li` tag.

Screen readers alert users when they arrive at a list and inform them of its length. Announcing the number of items in a list and the current item helps listeners understand what they are hearing and what to anticipate as they continue to listen.

If you do not mark up a list with the correct semantic markup in a hierarchy, list elements cannot alert the listener that they are listening to a list if no parent indicates the presence of a list and its type.
