What Is an Unordered List?

An unordered list displays items with bullet points — order does not matter:

<ul>
  <li>HTML</li>
  <li>CSS</li>
  <li>JavaScript</li>
</ul>

The ul Element

The <ul> (unordered list) element wraps the list. Only <li> elements should be direct children:

<ul>
  <li>First item</li>
  <li>Second item</li>
  <li>Third item</li>
</ul>
<!-- ul = unordered list (bullet points by default) -->
<!-- li = list item -->
<!-- Never put text directly inside ul without li -->

Styling Bullets with CSS

Control list markers with CSS:

ul {
  list-style-type: disc;       /* default: filled circle */
  /* circle, square, none */
}

/* Custom bullet with ::before */
ul li::before {
  content: '→ ';
  color: blue;
}

/* Remove all list styling: */
ul {
  list-style: none;
  padding: 0;
  margin: 0;
}

Navigation as ul

Navigation menus are semantically a list of links:

<nav>
  <ul>
    <li><a href="/">Home</a></li>
    <li><a href="/about">About</a></li>
    <li><a href="/blog">Blog</a></li>
    <li><a href="/contact">Contact</a></li>
  </ul>
</nav>

li Can Contain Any Content

List items can hold any flow content:

<ul>
  <li>
    <strong>HTML</strong>
    <p>The structure of the web.</p>
  </li>
  <li>
    <strong>CSS</strong>
    <p>The presentation layer.</p>
  </li>
</ul>

Inline Lists

Display list items horizontally with CSS:

<ul class="inline-list">
  <li>HTML</li>
  <li>CSS</li>
  <li>JS</li>
</ul>

<!-- CSS: -->
<!--
.inline-list {
  list-style: none;
  padding: 0;
  display: flex;
  gap: 1rem;
}
-->

Semantic Uses of ul

Common semantic uses for unordered lists:

Navigation menus
Feature lists
Tag clouds
Related links
Ingredient lists in recipes

ul vs p for Multiple Items

When you have multiple related items, a list is semantically better than separate paragraphs:

<!-- Bad: items that are actually a list -->
<p>- HTML</p>
<p>- CSS</p>
<p>- JavaScript</p>

<!-- Good: -->
<ul>
  <li>HTML</li>
  <li>CSS</li>
  <li>JavaScript</li>
</ul>

List Markers with list-style-image

Use a custom image as the list bullet:

ul {
  list-style-image: url('/icons/check.svg');
}

/* More reliable: use background-image on li::before */
ul li {
  list-style: none;
  padding-left: 1.5rem;
  background: url('/icons/check.svg') no-repeat left center;
  background-size: 1rem;
}

list-style Shorthand

The list-style shorthand sets type, position, and image:

ul {
  list-style: square inside;    /* type + position */
  list-style: none;             /* remove bullets */
}

/* list-style-position: inside vs outside */
ul {
  list-style-position: inside;  /* bullet inside padding box */
  /* outside = default, bullet outside text block */
}

Accessibility

Accessibility notes for lists:

Screen readers announce the list type and item count
Using list-style: none may cause some screen readers to not announce it as a list — add role="list" to preserve semantics

<ul style="list-style: none" role="list">
  <li>Item 1</li>
  <li>Item 2</li>
</ul>
