The lecture goes over writing an unordered list in HyperText Markup Language (HTML).

Those kinds of lists are also known as bullet lists.

The writing of unordered lists requires the use of two tags: the ul tag and the li tag.

The ul tag is the container tag for the whole list.

The li tag is the list item element that has to be written for each bullet point.

In summary, there is a single ul tag container with multiple list item li tags.
