CSS border-inline Property

Introduction

The border-inline property is a part of the CSS Border Module Level 3, which allows developers to control the borders of elements in a more flexible and precise manner. This property specifically enables the styling of borders on the inline sides of elements, providing a powerful tool for modern web design. Understanding the borders in CSS is crucial because they determine how elements relate visually to each other and their surrounding spaces, affecting overall layout and responsiveness.

Definition

What is the border-inline property?

The border-inline property is a shorthand property that applies styles to the borders on both the left and right sides (inline directions) of an element. This means you can easily set styles for inline-level elements without needing to style each border side individually.

How it differs from other border properties

While traditional border properties like border, border-left, and border-right allow users to customize borders, they lack the specificity needed for inline text elements. The border-inline property allows developers to manage these borders more effectively in a writing-mode context, optimizing layout in multilingual applications.
