🙋 Introduction

The list-style-type property in CSS is used to define the appearance of the list item marker for ordered lists (<ol>) and unordered lists (<ul>).

This property allows you to customize the bullets, numbers, or other markers that appear before each list item, enhancing the visual presentation of lists on your website.

💡 Syntax

The syntax for the list-style-type property is simple and can be applied to list elements (<ul>, <ol>, <li>).

Syntax

Copied

element {
  list-style-type: type;
}

Here, type specifies the marker type, which can be a predefined keyword or a custom marker.

🎛️ Default Value

The default value of the list-style-type property depends on the type of list:

For unordered lists (<ul>), the default value is disc.
For ordered lists (<ol>), the default value is decimal.
