CSS border-inline-width Property

Last Updated : 12 Jul, 2025

The border-inline-width property sets the width of an element's borders in the inline direction. It specifies the thickness of the inline-start and inline-end borders, adapting to the text direction. This property ensures consistent border styling in both left-to-right and right-to-left layouts.

Syntax:

border-inline-width: width;

Property values:

width: This property holds the width of the border.

The below examples illustrate the border-inline-width property in the CSS:

Example 1: In this example, we use border-inline-width to set the width of inline borders while retaining the overall layout with dashed borders and background colors for clarity.

        }

        div {
            background-color: yellow;
            width: 220px;
            height: 40px;
        }

        .one {
            border: 5px dashed cyan;
            border-inline-width: 2px;
            background-color: purple;
        }
