Article list in a news website made using CSS: ul is an unordered list in html, and li is a list item in the list. If there is no CSS to define its appearance, it will be displayed as a list by default, and it will have bulleted (such as squares or solid black dots) list contents. In CSS web page layout, in addition to making news lists and links using ul and li, we usually also use ul and li to implement menus.
