Unordered list
<ul>, ul, bullet list, bulleted listDefinition
The HTML element for a list whose order does not matter — <ul> with <li> children — announced by a screen reader as a list with its count, styled with bullets by default and with nothing at all when a nav or a card row needs the semantics without the marks
Most navigation is one: a <nav> wrapping a <ul> of links tells assistive technology how many items there are and where the list ends, which a row of <a>s in a <div> does not. The pattern this site uses everywhere — list-none on the <ul>, layout on the <li>s — keeps the semantics and drops the bullets; Safari once dropped the semantics too when list-style: none was set, which is why role=“list” sometimes appears beside it. The choice between this and <ol> is one question: would reordering the items change the meaning?
A group of things that are alike, in no particular order. If the order carries meaning, it is the other list; if the items are not alike, it is not a list.
