Create lists of related items using list elements appropriate for their purposes. The <ol> element is used when the list is ordered and the <ul> element is used when the list is unordered. Definition lists (<dl>) are used to group terms with their definitions. List items use <li> elements. Alternatively you may use WAI-ARIA roles and attributes for rendering the list properly
Engine scans for numbers followed by a punctuation character used repeatedly at the beginning of a string inside a section element like <p>, <div> etc.
When markup is used that visually formats items as a list but does not indicate the list relationship, users may have difficulty in navigating the information.
<ul>
  <li>Milk</li>
  <li>Eggs</li>
  <li>Butter</li>
</ul>
