Concept and Implementation

BDI stands for Bi-Directional Isolation. In the world of web development, handling text that might be in different directions (like English and Arabic) can be a challenge. The <bdi> tag comes to the rescue by isolating a part of the text that might be in a different direction from its surrounding text.

Example 1: Social Media Comments

Imagine a social media platform where users from around the world can comment. Some comments might be in languages that are read from right to left. Here’s how you can use the <bdi> tag:

<p><bdi>@john_doe</bdi>: Thanks for the great post!</p>
<p><bdi>@محمد</bdi>: شكرا لك على هذا المنشور!</p>

This code ensures that the usernames are displayed in their correct direction, providing a seamless user experience.

Example 2: Product Reviews

Consider an e-commerce site displaying product reviews from international customers. The <bdi> tag can be used to handle different languages:

<p><bdi>Anna</bdi>: Love this product! ⭐⭐⭐⭐⭐</p>
<p><bdi>يوسف</bdi>: هذا المنتج رائع! ⭐⭐⭐⭐</p>
