🔗 How to Use Bootstrap RTL CSS
Use Bootstrap’s RTL build by linking the bootstrap.rtl.min.css file in your HTML and adding dir="rtl" to the <html> element.
✅ Example HTML:
<!DOCTYPE html>
<html lang="ar" dir="rtl">
<head>
<meta charset="UTF-8">
<title>Bootstrap RTL Demo</title>
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.rtl.min.css" rel="stylesheet">
</head>
<body>
<div class="container text-end mt-5">
<h1>مرحبًا بك في Bootstrap RTL</h1>
<p class="lead">هذا تخطيط RTL باستخدام Bootstrap 5.</p>
</div>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/js/bootstrap.bundle.min.js"></script>
</body>
</html>
🔍 Code Explanation:
lang="ar": Declares Arabic as the document language.dir="rtl": Tells the browser to render content from right to left.bootstrap.rtl.min.css: Loads Bootstrap’s RTL CSS file.text-end: Aligns content to the right in RTL (same astext-startin LTR).mt-5: Adds top margin using Bootstrap spacing utility.
⚖️ LTR vs. RTL Layout Behavior
<!-- LTR layout (default) -->
<div class="container text-start">
<p>This is LTR content.</p>
</div>
<!-- RTL layout -->
<div class="container text-end" dir="rtl">
<p>هذا محتوى RTL.</p>
</div>
🔍 Code Explanation:
text-start: Aligns left in LTR; aligns right in RTL.text-end: Aligns right in LTR; aligns left in RTL.dir="rtl": Overrides direction for the container even if the document is LTR.
📐 RTL Utility Mirroring in Bootstrap 5
Bootstrap uses logical directional classes:
| Class | LTR Behavior | RTL Behavior |
|---|---|---|
ms-3 | Margin-left: 1rem | Margin-right: 1rem |
me-3 | Margin-right: 1rem | Margin-left: 1rem |
float-start | Floats left | Floats right |
text-start | Text aligns left | Text aligns right |
These classes auto-adapt when dir="rtl" is used in the HTML.
🛠️ Best Practices for RTL in Bootstrap 5
| Practice | Why It’s Recommended |
|---|---|
Use dir="rtl" on <html> | Enables full document mirroring for RTL behavior |
Use lang="ar" or lang="he" | Improves accessibility and SEO |
Prefer ms-*, me-*, text-end | Bootstrap automatically mirrors these in RTL |
Avoid fixed direction (e.g., ml-3) | Not mirrored—use logical classes instead |
| Test on both LTR and RTL | Ensure your layout responds correctly in both directions |
🧪 Example – RTL Bootstrap Card
<div class="card text-end" dir="rtl" style="width: 18rem;">
<div class="card-body">
<h5 class="card-title">عنوان البطاقة</h5>
<p class="card-text">هذا نص داخل بطاقة RTL باستخدام Bootstrap.</p>
<a href="#" class="btn btn-primary">اقرأ المزيد</a>
</div>
</div>
🔍 Code Explanation:
dir="rtl": Applies RTL logic to this specific card.text-end: Ensures text inside aligns to the right..card,.btn,.card-body: Bootstrap components that auto-adjust spacing and layout for RTL.
