About

ul is an element that represents an ordered list.

The difference with an ordered list is just the numeration of the list item. Unordered list items are not numbered.

If this is a list of action, you should used the menu element instead.

Example

Default

<ul> <!-- ul = unordered list -->
    <li>First Element</li> <!-- li = list item -->
    <li>Second Element</li>
    <li>Third Element</li>
</ul>

Without style

ul {
  list-style-type: none;
}
<ul> <!-- ul = unordered list -->
    <li>First Element</li> <!-- li = list item -->
    <li>Second Element</li>
    <li>Third Element</li>
</ul>
