marginend

Marginend is a CSS property used for specifying the margin space on the end side of an element. It is part of the CSS Logical Properties and Values Level 1 specification. Unlike traditional margin properties like margin-right, marginend is direction-agnostic. This means its behavior adapts to the text direction and writing mode of the document.

In left-to-right (LTR) text, marginend behaves the same as margin-right. However, in right-to-left (RTL) text, marginend corresponds to margin-left. This is crucial for creating internationalized web pages that adapt correctly to different reading directions without needing separate stylesheets for each direction.

The value of marginend can be a length (e.g., px, em, rem), a percentage, or the keyword auto. For example, marginend: 20px; will apply a 20-pixel margin on the end side of the element, regardless of whether it's the right or left side in the rendered output.

Using logical properties like marginend promotes more flexible and adaptable CSS layouts, especially for global applications. It simplifies development by abstracting away direction-specific concerns. Developers can set margins once and expect them to render correctly in various writing modes.
