CSS Lists

  • Learn CSS list styling to customize markers, spacing, and layout for ordered and unordered lists.

  • In HTML, lists are used to display multiple items in a structured and meaningful way.

    There are two commonly used list types:

    • Unordered List (<ul>) → bullets
    • Ordered List (<ol>) → numbers

    By default, browsers apply:

    • Bullets or numbers
    • Indentation
    • Basic spacing

    In simple words:

    CSS list styling gives you full control over how lists look and behave.

    Why Do We Style Lists in CSS ?

    Without styling:

    Lists look basic and outdated
    Not suitable for navigation or menus

    With CSS list styling:

    Clean and modern UI
    Professional navigation bars
    Fully custom designs

    Real-life comparison:
    A neatly printed restaurant menu looks far better than rough handwritten notes.

    CSS List Styling Properties 

    Removing Default Bullets

    Why remove bullets ?

    Bullets are unnecessary for:

    • Navigation menus
    • Website headers
    • Horizontal menus


Removing Default List Bullets

list-style: none; removes default bullets from lists, making them suitable for navigation menus and custom layouts. 

ul {
  list-style: none;
  padding: 0;
  margin: 0;
}

  • Removes bullets
    Removes default indentation

    Real-life comparison:
    Removing unnecessary symbols from a clean menu card.

    Custom List Markers

    Instead of default bullets, you can apply custom markers.


Custom List Markers

list-style-type changes the default bullet style to built-in marker types like square, circle, or numbers. 

ul {
  list-style-type: square;
}

  • Other values include:

     • circle
     • disc
     • decimal
     • lower-alpha
     • upper-roman

    Custom Symbols (Advanced Technique)

Custom List Symbols with ::before

Using ::before allows you to add custom symbols before list items instead of default bullets. 

li::before {
  content: "✔ ";
  color: green;
}

  • Fully customizable
    Modern checklist appearance

    Real-life comparison:
    Using icons instead of dots in a task checklist.

    Horizontal Menus Using Lists

    Lists are widely used to create horizontal navigation menus.

Horizontal Menu Using Lists

Lists can be styled with display: inline-block; to create horizontal navigation menus. 

<!DOCTYPE html>
<html>
<head>
    <title>Horizontal Menu Example</title>
    <style>
        body {
            font-family: Arial, sans-serif;
            padding: 40px;
        }

        .menu {
            list-style: none;
            padding: 0;
            margin: 0;
        }

        .menu li {
            display: inline-block;
            margin-right: 20px;
        }
    </style>
</head>
<body>
    <ul class="menu">
        <li>Home</li>
        <li>About</li>
        <li>Services</li>
        <li>Contact</li>
    </ul>
</body>
</html>

    Perfect for navigation bars

    Clickable List Menus

    Lists are commonly combined with links to create real navigation bars.

Clickable Navigation Menu

Lists combined with anchor () tags create real, clickable navigation menus for websites. 

<!DOCTYPE html>
<html>
<head>
    <title>Clickable Navigation Menu</title>
    <style>
        body {
            font-family: Arial, sans-serif;
            padding: 40px;
        }

        .nav {
            list-style: none;
            padding: 0;
            margin: 0;
        }

        .nav li {
            display: inline-block;
        }

        .nav a {
            text-decoration: none;
            padding: 10px 15px;
            color: black;
            display: inline-block;
        }

        .nav a:hover {
            background-color: #333;
            color: white;
        }
    </style>
</head>
<body>
    <ul class="nav">
        <li><a href="#">Home</a></li>
        <li><a href="#">About</a></li>
